Projects / ms-sys


ms-sys is a Linux program for writing Microsoft compatible boot records. The program does the same as Microsoft's "fdisk /mbr" to a hard disk or "sys d:" to a floppy or FAT32 partition, except that it does not copy any system files (only the boot record is written).

      Release Notes: This release adds experimental support for the Windows 7 NTFS boot record. Unfortunately, writing such a boot record with ms-sys is not useful if the intention is to get a bootable partition.
