If you have boot magic, I have fat32 drive C:, Drive D: and E: are ntfs and XP pro is installed on F: ntfs partition.
Before I tell you how to uninstall it, I want to ask you. When you booted with Boot Magic installed did it cause a crash?
Did you realise Boot Magic will only install on first drive, hence in my case C:?
I am such a tease, you have to uninstall it by inserting the partition magic CD r.o.m. select Boot magic folder on disk, open it up hit .exe to install then it will ask you if you want to repair or remove.
