I have a test system at work which has a hard drive with 3 partitions - Partition 1 FAT DOS boot created ( I think ) from a Windows 98SE DOS boot disk Partition 2 NTFS XP Pro Boot Partition 3 NTFS data The boot menu was to default to XP with the option to select DOS instead within 10 secs. I was trying to copy some files from a Win 98 DOS bootable USB pen to another. What I forgot to do was unplug the hard drive so when I typed SYS D: instead of transferring the system to the second USB pen as intended I transferred it to the hard drive ......... Now of course the hard drive boots to DOS only. Any suggestions restore the boot menu and run XP again will be appreciated. I assume the data in the third partition is still safe. There should be nothing irreplaceable on that partition but other copies will be scattered in several places.
