Recently we decided to dual boot with win98se and win2k pro. Everything was working fine we partitioned the harddrive and installed each os on different partitions. We were able to boot into either one. After We installed sp1 and sp2 on Win2k and then installed norton utilities. When we tried to boot to win98se we got "invalid system disk" I was wondering since I am not familiar with win2k if someone would have any input. I checked the msdos.sys and everything looks fine I haven't checked out the boot.ini yet.
