Question on partitioning for install in 42.2

I was trying to install Leap 42.2 alpha on the same HDD partitions as I previously had Leap 42.1 with a /boot/efi / and /home plus swap partitions but it complained that I did not have a BIOS partition for grub2. It would let me continue but I did not for now. My question is why? My current Leap did not have this and one of my TW install has just this layout and there was no issue with it. The problem with this is that there is no space on the HDD I want to use for this install so it tries to use free space on another HDD for this partition which I dont want it to do, I want Leap 42.2 completely contained on one HDD. I could delete the partitions except /home and reorganise but I really want to understand why this is necessary before I continue to test Leap 42.2.


Hi, following is my setup as seen from 42.1 which looks exactly what you describe.
Please note that sda5 is / root to 42.2 Alpha3, reusing /boot/efi, /home and [SWAP] and installed with no problem.
So what you describe sounds odd to me; can you add more detail? Was your 42.1 installed in UEFI mode?

LT_B:~ # lsblk
sda      8:0    0 232.9G  0 disk 
├─sda1   8:1    0   200M  0 part /boot/efi
├─sda2   8:2    0 175.8G  0 part /home
├─sda3   8:3    0    25G  0 part /
├─sda4   8:4    0    16G  0 part [SWAP]
└─sda5   8:5    0     9G  0 part 
LT_B:~ #

Both /root and /home are ext4.

That’s about what I did. However, I did not run into the same problems.

I’ll guess. You booted the install media in legacy MBR mode, instead of booting in UEFI mode. What you describe is the expected result.

You need a BIOS grub partition when the disk is GPT partitioned and you are booting from the MBR. But if you are doing a UEFI install, that should not apply.

In order to install this I created a bootable USB stick which I suspect is not booting in EFI mode on my desktop but I just tested it on the laptop and it did boot in EFI mode. I’ll see why later when I reboot this desktop.


Just tested again and yes I booted the stick in legacy mode not EFI, will do better next time and have learned something!


Have you set your desktop machine’s BIOS to preferentially boot in EFI mode?

My desktop m/b is an early implementation of EFI so I dont believe that is any way to force this. Leap 42.1 is non-EFI and my TW HDD boots in EFI. In order to boot the USB stick I have to hit F11 to see the boot options and I did not go far enough down to select the EFI USB option.
