[H-GEN] dual boot problems after upgrade to Ubuntu 10.10

[Peter Robinson]

The other day I upgraded to 10.10 and then tried to boot into my XP 
partition. It gives a blue screen of death with some text that goes past 
too fast to read and then automatically reboots. When I put in an XP 
disk it stops at the blue screen that says the disk has changed. However 
it freezes the system (so I can't do a recover) and I need a hard reboot.
Anyone else come across this? Any suggestions?
I don't really care about the data on the XP partition as I use 
VirtualBox when I need to be in Windows but I am a bit concerned about 
upgrading my home machine as my son uses XP sometimes.
