I used to use the alternate installer, but I see that's no longer available...

I have been using the MinimalCD: https://help.ubuntu.com/community/In...tion/MinimalCD

...The Minimal CD uses a text-based installer like the Alternate CD...

What has this never been fixed in the installer? I've been fighting this problem as long as I've been using Kubuntu (since 7.04).

Is there a bug report ?

**SteveRiley** · May 03, 2013, 12:35 PM

The minimal ISO lacks the proper configuration to boot a UEFI machine in UEFI mode. If you use it on a UEFI-based machine and:

BIOS compatibility mode is on, then the machine will boot into BIOS mode and the install will be for BIOS mode.
BIOS compatibility mode is off, then the minimal ISO will not boot the machine

The Server ISO can handle UEFI properly and uses the same Debian text-based installer.

The problem is that I've got the 1 TB disk divided up into 11 partitions, some that are used by Kubuntu exclusively and others that are shared by Kubuntu and a Windoze dual boot. when I get to about partition 9, the installer dies quietly. I used to use the alternate installer, but I see that's no longer available. Now, I don't do any formatting to any of the other partitions, but / and /tmp so can I get away without fussing with them and have then still show up in the fstab and get mounted at boot time later or am I going to have to figure out how to get these into fstab after the fact?

Had the exact same problem. Really annoying. It turned what should be a half hour install process into a half day long nightmare. Where does one file bugs about the installer...which package should we file a bug against?

How in the world did you make 11 partitions? LVM or GPT? MBR I think tops out at 5!

I have 13 partitions.

FAQ: How to Partition: http://www.kubuntuforums.net/showthr...on-Regenerated -> http://tldp.org/HOWTO/Partition/

3.3 Primary Partitions

...The original partition table was installed as part of the boot sector and held space for only four partition entries. These partitions are now called primary partitions...

3.4 Logical Partitions

...This is at most 15 partitions total on an SCSI disk and 63 total on an IDE disk...

I thought he had 11 primary partitions which is something you rarely see. I know it can be done with GPT but I've never seen it. On my one VBox .vdi I have 9 distros buy I only consider it to be 3 partitions.

With GPT, the notion of "primary" and "extended" partitions goes away. GPT places no hard-coded limits on the number of partitions. That said, implementations place limits, which can vary. More info: http://superuser.com/questions/30673...tions-with-efi

Holy crap, look at that list. Sort it by number and see how many are recent:

https://bugs.launchpad.net/ubuntu/+s...by=-id&start=0

And hardly any of them are getting attention:

**luggw1** · May 04, 2013, 07:44 PM

Well, I solved my problem by reducing the number of partitions below the threshold. I merged four partitions that I am not currently using into a single partition - seems to make more sense anyway. It doesn't really fix the problem with the installer, but gets me up and running.

Thanks for listening. It's good to know that I'm not the only one experiencing problems.

AFAIK: You can have 63 partitions on a non-GPT disk. Although I can't imagine why. I've hit 12 once in the past. Now with btrfs I have zero.

**SteveRiley** · May 13, 2013, 12:12 PM

There seems to be no universal consensus for the maximum number of GPT partitions. It appears to be at least OS- and disk-specific, possibly even more criteria. For instance, mine can apparently support 128 partitions:

Code:

Depends on how you work and what you're doing.

You have an MBR drive, on which you've created three primary partitions and one extended partition. The extended partition is type of container for additional partitions. This is pretty common for MBR disks.

With GPT, the concepts of "primary" and "extended" disappear. You simply have partitions.
