It took about 30 mins to do the bootcamp thing and about 1 hour to install XP (then an additional 1 and a half to install everything that i wanted on there.)
Your times will vary depending on how full your drive is, how faster your drive is, etc.
I'm having problems restoring my Boot Camp partition to a single volume after installing Windows Vista. The Boot Camp Assistant will get all the way to the end, prompt me to restart, but when I restart Windows Vista is still there.
Is there any way to restore my drive to a single volume?
i did that once, removing my boot camp partition, and it corrupted my drive, and couldnt be repaired with disk utility, although i could still boot and access my files and such.
