[Bug 1829774] Re: error

[TJ]

This appears to be caused by the partitioning on the target install
disk. In the UbiquityPartman.txt log-file it shows towards the end there
are 3 primary and 4 logical partitions, which means the disk label is
MSDOS not GPT.

Looking further there is no EFI System Partition on /dev/sda.

Therefore the problem here is that the Ubuntu installer was booted by
the PC in UEFI mode. You need to change that by selecting
Legacy/BIOS/CSM boot of the Ubuntu installer at boot-time.

If Ubuntu installer boots in BIOS mode this problem will not occur.

** Summary changed:

- error
+ GRUB fails to install to MSDOS label disk when PC booted in UEFI mode
