Bug Description
Binary package hint: ubiquity
On a MacBookPro (6.2) (without any OS on it), installing Ubuntu twice, with 'guided - resize' parititons option causes grub to fail to install, leaving both systems inaccessible.
TEST CASE:
First install Ubuntu using an "entire disk" install.
http://
This leaves a 1MB GPT partition at the beginning of the disk, a <size-of-RAM> swap at the end of the disk, and an ext4 partition filling the middle of the disk.
Then install Ubuntu again, using the 'guided - resize' partitions option.
http://
This suggests splitting the ext4 partition on sda2 about 50% and the subsequent partition table seems correct (screenshot attached).
But then:
Unable to install GRUB in /dev/sda
Executing 'grub-install /dev/sda' failed
This is a fatal error
In a terminal, I do;
sudo chroot /target; grub-install /dev/sda
This gives:
/usr/sbin/
Auto-detection of a filesystem of /dev/sda5 failed.
Please report this together with the output of "/usr/sbin/
The output of grub-probe is attached (from before the install, and from after the error).
It seems that I needed the device map from the live CD, which I unfortunately didn't manage to capture.
This is ubuntu-
grub-pc-
ubiquity-2.5.32

This grub error also occurs with kubuntu-desktop install and kubuntu-alternate install.
It does not occur on amd64 when following the same steps, only on amd64+mac.
