Comment 3 Barry Jackson 2017-07-24 14:57:24 CEST

Looking at the error messages above it seems to indicate that the drive in question may be GPT with a 'dummy MBR'.

In this case a BIOS boot partition would be required to install in PC_BIOS mode and the installer should have noticed this, unless the intention was to install in UEFI mode and the PC-BIOS installer was used in error?

It does appear that the installer was in PC-BIOS mode as grub2 (not grub2-efi) is installed as witnessed by the "Installing for i386-pc platform" message.

I just realized that these may not be installer related at all - to me it's not clear whether these are happening during an install or from within a working system using drakboot from mcc.

At least for the initial report of comment 0, it would be the latter:

It's also more difficult to retrieve such error logs from a failing install than from a working system where drakbug will pop up, so it's likely safe to assume that the duplicates are also from a live system.

Comment 6 Barry Jackson 2017-07-24 17:39:45 CEST

Right, looking at the dates the only recent one is 21320 which was using mcc->drakboot in Mga6 after upgrade from Mga5.

If the Mga5 was PC-BIOS using grub legacy then it would update to Mga6 with grub legacy, so this is a different bug to the others as there is no suggestion of GPT. (the others mention 'dummy MBR' which to me implies GPT)

Maybe 21320 should not be marked as a duplicate of this one, it is new, different and the others (this and the other dup) are 6 months old cauldron.
