grub2 installation fails on 14.04 kickstart installation

Discovered in version: 14.04
Last known good version: 12.04

Hi!

I got hit by a bug that grub2 could not be installed when using 14.04 - while the exact same kickstart file works perfectly when using 12.04 for kickstarting.

The exact error (after the installer fails, and before pressing enter to continue) in tty4 is: "disk hd0 not found".

I'm attaching a screenshot of the error, when the automated installer fails.

The kickstart file snippet regarding bootloader installation after partitioning is this:

-----<snip>-----
zerombr yes
bootloader --location=mbr
clearpart --initlabel --drives=sda
part /boot --fstype=ext4 --size=256 --asprimary
part swap --size=512 --asprimary
part / --fstype=ext4 --size=1 --grow --asprimary
-----<snap>-----

I am running the installation using the 14.04 server beta2 cd, and adding "toram ks=http://mylocalwebserverip/ubuntutest.ks" to the kernel options prior booting, the result stays the same without "toram".

Best regards,
bekks

Added the output of:

grub-install --verbose --force "(hd0)"

from within a chroot created with "chroot /target /bin/bash" right after the installer failed.

Added the output of:

grub-install --verbose --force /dev/sda

from within a chroot created with "chroot /target /bin/bash" right after the installer failed.

This works fine, and exits with $? being 0.

This looks identical to bug 1292628, which should be fixed in more recent daily builds; the fix missed beta2 by a day or two, though.
