>From what you report I would say, some essential fields of the boot
sector were overwritten. Fortunately there exists a backup boot
sector. Under linux try this:
# Save the image of the corrupted dos bootsector in case something
# gets wrong:
dd if=/dev/hda1 of=/root/boot.hda1 count=1
# Get the backup bootsector:
dd if=/dev/hda1 of=/root/backupboot.hda1 count=1 skip=6
# Replace boot sector by its backup:
dd if=/root/backupboot.hda1 of=/dev/hda1 count=1
For the same procedure under windows see this:
