i recently was going through old hard drives, and checking to see if any data was on any of them. while doing this i left my good harddrive attatched. i installed one hard drive and it had a version of win 98 on it, while doing so my winxp harddrive file format ntfs was still attatched. the comp. booted to Win98 and didnt recognize my winxp harddrive as being there. i found no files useful on win98 hd; shut down removed hd and installed different hd. up reboot my comp goes to a multi color squared pattern with random characters and doesnt boot to xp @ all. is this a virus or did i wreck somethin by having the win98 hd in?
