Bug Description
Binary package hint: grub2
(sorry if I don't do this right, this is the first bug I have ever reported.)
After an install of Karmic Koala using Wubi and updating completely when you restart the machine it fails to give the boot options out of boot.ini. Instead it immediately starts the Grub menu and when you select Windows XP it fails to start by giving the error...
error: unkown command 'drivemap'
The ubuntu selections keep working. The only way to fix this is to redo the MBR with Microsofts. I have used the package ms-sys and 'sudo ms-sys -w /dev/sda' which on reboot gives me the option to boot Windows or Ubuntu.
Also, even when doing this when you select Ubuntu it quickly flashes an error, although I can read it, grub menu still shows up.
I have been able to replicate this problem twice today. Oct 24, 2009
