Comment 2 for bug 19026

I can confirm the bug using 5.10 Breezy Preview. Steps to reproduce:
1. Install
2. When asked if you want to install grub to MBR, answer yes
3. In the reboot, system hangs in boot and displays "Error loading operating
system."

Note: I found a funny workaround to the problem. When I put a Windows XP
installation CD in my drive and boot but don't press any key when prompted, grub
is loaded and I'm able to boot into Ubuntu.

After this bug has happened, only way I have been able to get the computer to
boot is by formatting /dev/hda1 (where my Windows XP is) and delete partition
/hdb2 (where I tried to install ubuntu). I could not even install Hoary (which
worked previously fine) after the computer is in an unbootable state.

I can provide more information if needed.
