This is the first time I've used Parallels with a Boot Camp partition. This is a freshly installed Core 2 Duo 17" MBP. I just finished my XP SP2 installation with Boot Camp and it works fine. I loaded build 3170 and told it to use Boot Camp. When it tries to boot it just gives a bluescreen/STOP message right after choosing the Parallels config boot option. No bluescreen error just a STOP code. It will just sit and repeat over and over. Ideas?
