Trying to make my new Acer Aspire laptop dual boot with windows 8.1.

[geezer]

Okay - was able to do another install. First it refused to let me specify the mount point for the efi partition. So I just went ahead with the installation anyway. I had used the windows disk manager to shrink the windows partition and left empty space. Used th einstallation to divide that into 3 partitions: 1)swap 6GB, 2) root partition (I like to have my '\' directory on a separate partitio - probably just inertiua oin my part, this is the way I have done for many years now. Probably wastes a lot of storage space since I specify 100 GB for it and it only uses about 11 GB. 3) a separate partition for '/home'.

The installation went to completion. I rebooted and nothing in the list - for Kubuntu. Just windows 8.1. Tried rebooting in legacy mode that takes about 3 minutes while it is doing something to do with the GUID and DHCP

Then it informs me that there is no MBR. Okay - that's reasonable since I installed with the UEFI mode. Rebooted and turned on UEFI mode again and boot the Kubuntu Live DVD and clicked on Run Kubuntu. boot Dolphin there and looked at the partitions for '/' and '/home' that the installation should have populated. The '\boot' directory had a mount point for 'efi'. Then I looked at what should have been my 'home' directory, '\home\terry' Nothing there. Totally empty.

I appears that the installation is not really completing. Maybe since the installtion doesn't really run to completion, the Kubuntu boot files don't really get setup to use, even though I peeked in the 'efi' partition and the files seem to be there.

Something weird is going on. I had checked the sha256sum after downloading the ISO file. I just checked it again and it matches what the download site specifies.

Weird.

You should not have to specify the mount point for the efi partition -- the Kubuntu installer will detect it and list it with no problem.

Used th einstallation to divide that into 3 partitions: 1)swap 6GB, 2) root partition (I like to have my '\' directory on a separate partitio - probably just inertiua oin my part, this is the way I have done for many years now. Probably wastes a lot of storage space since I specify 100 GB for it and it only uses about 11 GB. 3) a separate partition for '/home'.

I would not allow the Kubuntu installer to do any partitioning for me.

/ root partition for Kubuntu: you're right, even 30 GB should be more than enough for most people. (I use just 6 GB, many people use up to 15 GB.) Yes, having a separate /home partition is nice/useful.

Then it informs me that there is no MBR.

If you are installing in UEFI mode on a GPT, you should not be getting an error message like that at all.

Now, the fact is, Boot Repair should fix this. But it does sound like you are missing some subtle detail. For example, There should be no mention of any "MBR."

When you run the Kubuntu installer DVD, you do make sure that your computer is booting that DVD in UEFI mode, right?


My spiel on installing Kubuntu, FWIW:

Installing Kubuntu -- Using the "Manual" Installation Type

Two steps:
-- First, set up your partitions for Kubuntu.
-- Then install Kubuntu using the "Manual" method of installation.


Step 1:
Partitioning for Kubuntu

Many long-time users of Kubuntu prefer to do their own partitioning using GParted (or other similar programs) instead of doing allowing the Kubuntu installer to do the partitioning.

So, use GParted to partition your drive for Kubuntu, making partitions for root /, and /home (if you use a separate home partition), and swap. If you already have swap partition set up for another K(Ubuntu) OS, you do not need to create another swap partiton for the Kubuntu version you are installing now.

You can use GParted from another installed Linux OS on your computer, or you can use GParted Live CD/USB. In Kubuntu, you can install gparted using Muon. After doing so, you will probably find it here: K > Applications > System > Partition Editor (GParted).

GParted Live CD:
http://gparted.org/livecd.php
The Manual shows you how to do parttioning operations:
http://gparted.org/display-doc.php?n...ed-live-manual
Make sure you choose the right version of GParted, read the Note:
http://gparted.org/download.php


Step 2:
Install Kubuntu using the "Manual" method of installation

Download Kubuntu, check it, and make the installer medium
Download the correct version of Kubuntu (use 64-bit for newer UEFI+GPT systems). Run checks on it (MD5 or Shasums).
Burn the iso image to DVD (using K3b or similar), or make a live USB flash drive
( https://www.kubuntuforums.net/showth...aller-using-dd ).

Boot your computer with the Live Kubuntu medium
Reboot your computer with the DVD or flash drive installed.
At the computer's POST screen, hit the proper key to enter the firmware ("BIOS") setup.
Locate the boot or boot override menu.
Select the DVD or USB flash drive to boot from.
(If you are installing in UEFI mode: Your DVD or flash drive may have more than one boot menu entry; choose the entry that says UEFI or EFI.)
--> Thus, boot your PC with the DVD/USB Kubuntu installer medium.
Get to the Kubuntu welcome page and select Install Kubuntu (your other choice will be to Try Kubuntu [without installing]).

Installation Type screen: Select Manual.

Prepare Partition screen (the left side bar may say "Disk Setup"):

You will see a list of all your partitions, including those you created in GParted for Kubuntu.
Highlight a partition you want to use (for example, for root / or for /home or for swap).
Hit the Change button.
You will see a menu called Edit Partition.
New size: do not change what you did in Gparted, leave it as it is.
Use as:
Format partition: No, do not check this box -- leave the format as you did it in GParted.
Mount point: Drop-down list: you will see /, /home, etc. If in GParted, you formatted it as swap, you will also see that choice here. Choose one.
Hit the OK button.
Repeat this by highlighting another partition you wish to use for Kubuntu (/, /home, swap).
Bootloader:
When you are done you may also see a choice where to install the bootloader (GRUB2). You can say sdX, where X is the drive you wish GRUB to go on; if you are using UEFI mode, it doesn't matter what you say here: GRUB will go to the ESP, usually sda1, automatically; thus, you can say sda, if you wish.

Finally, click Install Now.
(Or, you can click Back; or Quit if you wish to NOT install Kubuntu at this time.)

Note:
Since you did your partitioning ahead of time using GParted (or similar), there are other options you will see that you will NOT use, like these: new partition table, Add, Delete. If you make any mistakes or are not sure about what you did, there is a button called "Undo all changes."

It is worth a LOT. More detail than I have seen anywhere else and more insight. Now to read it thoroughly and try to understand what is going on with my system and why my laptop consistently refuses to list the Kubuntu install at boot time.

I have started doing all of the (re)partitioning in windows 8.1. I get a more stable partitioning that way.

/ root partition for Kubuntu: you're right, even 30 GB should be more than enough for most people. (I use just 6 GB, many people use up to 15 GB.) Yes, having a separate /home partition is nice/useful.

I have resized. On my desktop I use the SSD for the '/' directory. It is 120 GB and uses all of 11 GB :-). So far I am too lazy to rearrange things and have just let it slide since the 2 hdd's are 2 TB each. I have allocated the fourth hdd to Windows 8.1 entirely 500 GB since in the past i have found that windows is very wasteful of disk space and complains bitterly and slows down to a crawl.

If you are installing in UEFI mode on a GPT, you should not be getting an error message like that at all.

Sorry - I wasn't very clear. I had done som work in the BIOS and changed from UEFI boot to Legacy boot. The legacy boot process then did something and displayed a progression of dots and a rotating bar to indicate that it was busy. That took about 3 to 4 minutes. I waited through that process twice and changed the BIOS back to UEFI.

Now, the fact is, Boot Repair should fix this. But it does sound like you are missing some subtle detail. For example, There should be no mention of any "MBR."

Yes I see the UEFI selection screen when booting the LiveDVD

[geezer]

I have been learning more. I repartitioned using the Windows disk manager and installed Kubuntu again. This time from a USB liveKubuntu. Much faster.

Still could not get Kubuntu listed on the boot screen. Ran Boot-Repair again and then in windows 8.1 ran the command that the Boot-Repir suggested:

bcdedit set {bootmgr} path \EFI\ubuntu\shim64.efi (I might have that a little - writing it from memory).

Booted again and still only windows. So in windows I ran 'bcdedit' and gort the following output:

So that tells me that the Boot-Repair suggested command has enetered the Kubuntu OS into the boot manager, but I still have no way to load the OS. Now I have to learn how to specify the Boot Loader and maybe then Kubuntu will be listed on the boot screen options.

One thing still bothers me about the bot manager entry that I created with the bcedit command. It lists

device partition=\Device\HarddiskVolume2

windows thinks the '/' directory partition is 'F:'. So shouldn't that line be instead:

device partition=F:

mimicing the windows 8.1 entry?

Definitely need a Windows boot "helper" here! Sounds like your goal is to let the Windows boot manager boot both Windows and Kubuntu? The other way, as we know, is to let the GRUB boot loader from Kubuntu take over the boot show and boot Windows and Kubuntu.

The strange thing is that usually, when you have Windows already installed, and then you install Kubuntu and its GRUB, that GRUB aggressively takes over the show! It installs itself in place so it boots both Windows and Kubuntu. In UEFI, that GRUB would set itself as first in the UEFI BootOrder, whether you like it or not. In your case, it clearly is not doing that; in fact, it is not clear what is going on with your GRUB, why it is not working.

If you could, by hook or by crook, boot into Kubuntu, then you could re-install GRUB by
sudo grub-install
sudo update-grub
--as you know.

Or, re-install GRUB from your Live Kubuntu DVD/USB,
https://www.kubuntuforums.net/showth...l=1#post374017

Another option here is to install the very good boot manager rEFInd! Let it run your boot show, let it get Kubuntu booted, and Windows, too.
http://www.rodsbooks.com/refind/getting.html

FWIW, I have both GRUB and rEFInd working for me on this PC -- It is almost impossible for me to end up unable to boot what needs to be booted!

I'll continue to think about this, but am limited by my limited knowledge of Windows (beyond XP!).

[Qqmike]

I do realize you are comfortable with the Windows disk manager-partitioner. I hope that is not causing the problem here! If you were to use GParted Live CD/USB to make your partitions for Kubuntu, I just can't imagine that you'd be having this problem, unable to get GRUB installed properly.

I wonder, did I forget that you did this?, what the picture of your partitions look like on that disk? If you were to boot your Live Kubuntu DVD/USB, then install gdisk in that live session (using Muon or at Konsole using the command: sudo apt-get install gdisk), then run this command at Konsole:
sudo gdisk -l /dev/sda
I wonder how we'd see your partitions (and your partition table, which we hope is GPT, and we hope your EFI System Partition is OK), in Linux terms ...

I did the re-install of GRUB from the LiveDVD - no change.

Until the boot loader or boot manager or whatever is working here is working I have no way to get the installed Kubuntu to boot.

I would like to try rEFInd, but from I have read thus far I have to install that from (K)Ubuntu, which I have not been able to boot. Catch 21.

Is it possible to install rEFInd from the LiveDVD?

The last time this morning that I booted the laptop, I took a good hard look at the selection screen. Across the top it states quite clearly that it is the "Windows Boot Manager". Now that puzzles me even more since I thought that the Windows Boot Manager read the BCD and took it's directions therefrom. So it would seem that either: 1) the BCD entry for the Kubuntu installation that Boot-Repair suggested is incorrect and thus ignored, or 2) the boot loader in the /efi/ubuntu/shim64.efi file is not recognized by the Windows Boot Manager. Or maybe something else entirely?

I downloaded Resctux and loaded onto a USB drive. Iw would not boot. Read their web site a little more - it doesn't work with UEFI computers.

Still reading and trying at this point.

Also, I'm not really committed to any particular boot manager/loader. Just something that works reliably.

From what I read in your discussion with SteveRiley, rEFInd sounds like the best of breed now.

I booted the LiveDVD and installed gdisk and ran it as you suggested - here are the results:

Is it possible to install rEFInd from the LiveDVD?

What I have seen is people putting rEFInd on a live, bootable flash drive and using it from there. When you boot your PC, that rEFInd flash drive must be plugged in, though. The rodsmith website should tell how.

The output of gdisk looks normal. You have an ESP, the EFI System Partition, and partitions for Kubuntu, and it is a GPT.

When you were in the Live Kubuntu session, I forgot to have you run another very informative command, efibootmgr. You might have to install it in the live session, I'm not sure. It tells you your UEFI boot order, so you could see Windows probably being first in order. But it should also show you the Kubuntu-GRUB loader, we hope being second in order.

When you re-boot your PC, can you not interrupt the POST by pressing a key, get into your PCs UEFI ("BIOS") setup, and see the list of OSs available to boot? You should be able to do this. And from one of those boot menus, you should be able to select Kubuntu to boot (instead of letting it automatically select Windows to boot). Every PC maker sets up its UEFI firmware differently, but I would think Ace should provide this capability. Sometimes in that firmware setup, there is more than one boot menu, like a boot override menu, which you could use on THAT booting session to boot into Kubuntu. Maybe you could try that, explore those firmware menus in "BIOS" (which is actually UEFI setup now).

Here's my output from efibootmgr, run with sudo, btw:

sudo efibootmgr
[sudo] password for mike: 
BootCurrent: 0000

Boot0004* UEFI:Removable Device
Boot0005* UEFI:Network Device
Boot0007* Hard Drive 
Boot0008* CD/DVD Drive

The first thing in BootOrder is Boot0000 *ubuntu, which is my Kubuntu 14.04 (the asterisk * indicates that the ubuntu entry is active in the current boot order, it is included in the game).

The second thing in BootOrder is 0003 = rEFInd, and rEFInd, will boot anything on my PC! When my PC boots (it's an ASUS), I can press F2 to enter UEFI setup, I can access a boot override menu that lists all these options, and I can highlight-click an entry to boot that one time for that booting session, and it will boot.

That third thing is 0002, grub_sda5K1504: that's a name I made up for a grub that I installed as a test/experiment that would boot a Kubuntu 15.04 that I have on another partition.

[geezer]

Here's my output of efibootmgr:

[Qqmike]

Very strange, it seems. Maybe we need fresh eyes on this. Or extensive googling. Just one hard drive, just 2 OSs, but this isn't coming through as routine. (And I think we did agree that you are using the 64-bit (UEFI) version of Kubuntu, not the 32-bit.)

Not clear what 2001 is. And you've got a network boot facility, 2003, too!? What is that? We do see 0000 = Windows. But no ubuntu. If you boot into Windows and access the ESP (is it sda2?), and look inside it, is your Kubuntu there? It would appear as:
/EFI/ubuntu
and inside that directory would be the GRUB boot files for booting Kubuntu, something like:
grub.cfg, grubx64.efi, shimx64.efi, and MokManager.efi

[Qqmike]

I wonder if your luck would change if you tried installing Kubuntu 14.04 instead of 15.04?

Looked in the \EFI directory
Have the following directories:
Ubuntu
MicroSoft
boot
OEM
refind

The last because I installed refind under windows following the directions on that site.

The boot process is totally unchanged.

I'm beginning to think that the MBR is playing a role in this in some manner. When I ran Boot-Repair it listed the MBR as "protective" whatever the heck that means. The output is here:

http://paste.ubuntu.com/11789831

What would happen if I zero out the MBR?? Since it booting EFI the MBR should not be used and so zeroing it out should not be detrimental. But everything I have done has had zero effect on the Windows Boot Manager boot options screen. Maybe there is something in the MBR now that is doing that. I remember when I first booted the computer, There was a boot options screen that was a little fancy. The screen was blue with four or five options to boot - Windows, CD/DVD, USB, network and I think something unknown. I have not been able to get that options screen back. The "Windows Boot Manager" screen is white on black and utilitarian. Nothing fancy.

Just looked at the hex dump for the MBR from Boot-Repair. There is definitely something there now. Maybe Boot-Repair wrote something to the MBR that really causing a problem? Yeah looking at that Boot-Repair report Boot-Repair definitly overwrote the MBR with something from GRUB. Maybe that has frozen the boot into the Windows Boot Manager and I have to undo that "repair".

[Qqmike]

My Protective MBR looks like this, as you can see, it is not empty, it has one "row" with something in it, as I've noticed it usually does (and the 55 aa at the end, as you probably know, is normal, it is just something like an EOF = end of file marker for the MBR):

00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00  |................|

00000200

In your UEFI firmware setup, you are certain that you are NOT booting in CSM mode? or in Legacy mode? (if it has that as an option). It's OK to have a Protective MBR, and something may be in it, as long as your UEFI firmware setup (in "BIOS") is NOT set to boot in any Legacy or CSM mode.

You have rEFInd installed in Windows? But when you re-boot, you do not see any option to select rEFInd?

Can you look inside your ubuntu? (But I'll bet it is OK, I'll bet it has the right files in it).

Can you run again sudo efibootmgr and see if rEFInd is listed?
If it is listed, you could use erfibootmgr to change to boot order so rEFInd is listed first.
See man efibootmgr, at the end, see Example 3:

3.

Changing the Boot Order

Assuming the configuration in Example #1, efibootmgr -o 3,4 could be called to specify PXE boot first, then Linux boot.

Can you play the the above tips? --> try to find a way to boot rEFInd; use efibootmgr again to find the BootOrder, see what's listed; using efibootmgr to re-order the BootOrder.

I am almost suspicious of your UEFI firmware! Why is it not picking up everything? why can't you find a boot menu in the UEFI firmware menus that shows everything--Windows, ubuntu, refind, etc.?

The other thing, recall, is that rodsmithbooks somewhere shows how to put rEFInd on a bootable flash drive, and you can boot your PC with it, and then it should show ALL you boot options, we would hope.

[Qqmike]

Btw, your Protective MBR is there (in your GPT) in case you did want to boot your PC in the older legacy-BIOS-MBR mode. But to do so, you'd have turn that option on in your PC's UEFI setup menus, and usually, you also need a 1 MB bios-boot partition set up to hold Stage 2 of GRUB Legacy. But, again, since you are using UEFI mode, none of this applies.
