I just installed Kubuntu 14.04 64bit, for a friend on an HP 2000 laptop, it came with uefi and win8, now, I have Kubuntu installed but if I reboot it goes straight to win8, no grub menu, if I hit escape, followed by f9, cursor down to Ubuntu, it will load the grub menu and then open Kubuntu. How can I stop this, secure boot is disabled, legacy was disabled at install time, but changed to enabled, with no help in booting to Kubuntu.

Messing with Windows is always risky, but ...
Make sure "legacy" is disabled.
Many users who have Windows also disable Secure Boot (because, they say, it causes more problems than it solves).
Boot into Kubuntu (the way you said you could).
Open Konsole. Issue these commands:
sudo grub-install
then
sudo update-grub
See if that gives you a controlling GRUB menu that also shows the option of booting into Windows.An intellectual says a simple thing in a hard way. An artist says a hard thing in a simple way. Charles Bukowski -
didn't seem to help, when i did update grub it looked like it found everything, just won't give me grub without going through the hoops
something looks funny here though
should I reinstall with secure boot turned back onComment

I can get to this grub menu , but I have to go through the bios to do it.Originally posted by Qqmike View PostComment

Yes, try that. And Legacy should be turned off (or, turn off CSM, if you see that option in "BIOS" -- IOW, UEFI/EFI should be turned ON). Then re-install Kubuntu. Now, when you install Kubuntu, do so in UEFI mode -- very important -->should I reinstall with secure boot turned back on
To install the Kubuntu OS in UEFI mode
--> Must be 64-bit Kubuntu OS for UEFI.
--> You must boot your Kubuntu installer DVD/USB in UEFI mode!
With the DVD/USB installer inserted in the computer, reboot the PC, enter the computer's UEFI setup by pressing the correct key for your computer (F2, F1, F12, etc.).
Find the boot menu or boot override menu where the bootable devices will be listed.
Choose the one that corresponds to the Kubuntu UEFI DVD or USB choice.
Look for UEFI/EFI (FAT) or some reference to UEFI.
Example: My Live Kubuntu DVD installer showed up twice in UEFI BIOS (under Boot Override) as a "normal" DVD writer, and also as:
UEFI (FAT) TSSTcorp CDDVDW SH-224DB (1028 MB) (= my Samsung DVD player).
Select the UEFI/EFI option from the boot [override] menu.An intellectual says a simple thing in a hard way. An artist says a hard thing in a simple way. Charles BukowskiComment

Hopefully, Post #5 will set everything straight.
(backtracking ... I just saw this
If you indeed do have Kubuntu installed in UEFI mode, but it is simply out of order, you could change the order of the UEFI Boot entries.I can get to this grub menu , but I have to go through the bios to do it.
Boot into Kubuntu,
sudo efibootmgr
to see your boot order.
Then see
man efibootmgr
to see how to place your Kubuntu as first in boot order (read toward the end of that man page, down to the examples). Windows should be on that GRUB menu. If not, from within Kubuntu
sudo update-grub
should place an entry for Windows on that GRUB menu.An intellectual says a simple thing in a hard way. An artist says a hard thing in a simple way. Charles BukowskiComment

Post #2 didn't work. I have turned on secure boot, turned off legacy, went into win8 disk management, deleted partition Kubuntu was on, now said unknown or something like that, went to reinstall from disk and briefly saw error and uefi in the same line but continued to install to same partition as before. There is an efi folder on the install disk also. OK, part one of post 6 below, I'm lost now I think looking at "man efibootmgr", gonna "sudo update-grub" and reboot, c what happens.

No dice, went straight to win8 at reboot. I stuck the install dvd in and rebooted, cdrom is first in boot order in bios:
start button
hit escape to enter bios
hit f9 and get list:
1. Internal cd/dvd rom drive (uefi) (when rebooting without dvd in tray this does not show up)
2. OS boot manager
3. ubuntu
4. Ubuntu
5. Boot from EFI file
I choose #1 and hit enter, and "could not open \efi\boot\falback.efi "14" or something like that pops up then goes away quickly, then I am asked to install or some other choices.
If I hit f9 and choose #2, obviously boots into win8, #4 boots into win8, #3 takes me into the real grub menu, gives me the version number at the top but don't remember what it was, then I can get into Kubuntu.
Even though its not booting properly, Kubuntu still runs a lot better on this machine than win8 does, 1.3g apu with 2g ram, not much.Comment

Post #9,
Before doing sudo update-grub, you need to do sudo grub-install: That SHOULD place Kubuntu #1 in BootOrder. Then sudo update-grub should put Windows on the GRUB menu. But I think you are saying that it didn't?No dice, went straight to win8 at reboot.
So,
Post #10,
Yeah. And, you know, chicken superstition ... I'd go ahead and write,So boot0000* needs to be before 3001 right,
efibootmgr -o 0,1 ?
efibootmgr -o 3000,3001,3002,2001,2002,2003

That fact that efibootmgr works for you tells you that Kubuntu is installed in UEFI mode, btw.An intellectual says a simple thing in a hard way. An artist says a hard thing in a simple way. Charles BukowskiComment

Nope, rebooted into win8 again, after esc and f9, boot option menu still has "os boot manager" on top with ubuntu 2nd on list still,Last edited by Clayman1000x; Nov 29, 2015, 03:49 PM.Comment

Yes it does look promising! Ubuntu 0000 is first--it is supposed to boot first! Unless your UEFI firmware is messed up (doubtful); unless Windows has screwed with something (who knows); unless ... Ubuntu did boot first but its GRUB boot menu (/boot/grub/grub.cfg) is set to boot straight to Windows by default? I've never heard of that happening, but it looks like it could have happened here. You could inspect /boot/grub/grub.cfg and see if it is set to boot without delay to Windows. Configuring GRUB2 by editing (as root) /etc/default/grub:BootOrder: 0000,3001,3000,3002,2001,2002,2003 (< that looks promising gonna reboot again)
https://help.ubuntu.com/community/Gr...iguring_GRUB_2
It shouldn't be this tricky.
One thing you can do is install the boot manager rEFInd, and let rEFInd run this boot show. I like rEFInd, it is written by the UEFI expert Rod Smith. You can install it right along side all your other stuff (GRUB2, Windows boot manager, whatever), it won't interfere at all, no harm done. When you boot the PC, you'll see a boot menu from rEFInd. If you ever get stuck booting, rEFInd can usually save the day.

My GRUB2 menu shows a 10 second timeout (so you can see the GRUB2 boot menu for 10 seconds), and by default it boots to 0 (which is the position of my Kubuntu -- it is listed first in the /boot/grub/grub.cfg).
In /etc/default/grub, I see
Code:[B]GRUB_DEFAULT=0[/B] GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true [B]GRUB_TIMEOUT=10[/B]
