"Cannot install Generic volue" error

[geek@02]

Hi!
i split my primary disk partition (ntfs) and created 2 logicals- a fat32 and an ext2. i used the fat32 to install Boot Magic, cos it asked for a fat32. but when i'm installing linux, again i merged the fat32 and ext2 into a single ext2 distroying the data in fat32. now i'm dual booting winxp and linux, but every time i log on to xp, there is always an anoying message from 'new hardware wizard', reading that there's a problem installing 'Generic volume'. may be that has something to do with that deleted partition where Boot magic has been? anybody know a way to fix this, so that message wouldn't appear?
THANX.
