Actually I believe 98SE would have to be installed BEFORE WinXP or the dual boot functions won't work correctly... What I did was partition my 60GB Maxtor into 3 20GB partitions... Partition 1 (C is windows 98SE FAT32, Partition 2 (D is WinXP NTFS, and partition 3 (E is a fat32 shared drive that both OSes can read since 98SE won't read NTSF... So if you wanted to do something like this use XP to export all you're settings to a CDR or Zip drive and reformat, partition into three partitions and install 98SE, you could specify for it to install to D: I believe and install XP to C but XP will always be the boot drive since it will handle the dual boot fuctions, hope this helped some...
