23 The first partition has FreeDOS I think and a couple of recovery tools.
24
25 The second partition *should* have a backup of the MSWindows OS _and_ the boot
26 files. If you less about with it you will probably find that your MSWindows
27 OS does not boot anymore.
28
29 The third partition should have the MSWindows OS.

31 A quick check for finding a file called BCD and perhaps BCD_backup will show
32 you which is the boot partition.

35 If you are still under warranty you may want to install GRUB in your Linux
36 /boot partition not in the MBR and then copy an image of the boot partition
37 record from the Linux /boot partition to a file in your MSWindows OS
38 partition. I have detailed how to chainload Linux from MSWindows in this
