Boot into NT, from there edit the boot.ini file... you need to have a small understanding of ARC paths to do this... you will see at least two lines that look like a bunch of gibberish... one of these has two point to the win98 partition, and have the corresponding identifier so you know which one you're choosing... check M$ knowledgebase for info on editing the ARC path... when you copied the bootsect.dos back on, it is the old config and not the new one... when you created the partition for 98, did you place it before the NT partition or after? If you placed it after the NT partition you shouldn't have recieved the error, if you placed it before NT - well, you still need to edit the boot.ini file..
