Comment 6 for bug 1015880

What exactly I encountered after choosing "Something else":

#1: When choosing the mount point my choice "/" failed to display as it should. But after letting the installer proceed "/" did display properly in the list of partitions. This is possibly a separate bug.

#2: In the grub install region /dev/sdb was the default and I was unable to change that visually. I still chose /dev/sda to see what would happen and when the installation was nearly complete I was informed that grub install had failed. Then I was given the choice to either choose a location or continue w/o bootloader. I chose /dev/sda and after doing so I went to the live DE as expected, being presented with the option to either continue testing or reboot and I chose continue testing.

#3: After choosing continue testing I got an automated installer crash report but trying to let it complete resulted in bug 1018032.

Not sure what else to add. It doesn't help when apport is uncooperative.
