MS-DOS: "Unable to write BOOT"
 

I tried searching for this problem and didn't find anything, so bear with me if it's come up before.

I recently installed Linux on one of my hard drives, but now want to return it to a Windows hard drive. I used MS-DOS's FDISK to delete the Linux partitions and make a new DOS partition. When I formatted the drive, it sucessfully formatted it but then came up with the error message:

"Unable to write BOOT"

Does anyone know how to fix this? Should I use a Linux-native FDISK program?

Try reinstalling the mbr - on win 9x:
fdisk /mbr

Still get the error.

When you rewrite the partition table of a disk, and a mounted partition is affected, you get this error (probably even in DOS). Try using a Linux bootdisk to change the partitions, and format them in DOS.
