Fix Windows MBR using Ubuntu Live CD
- by kova
I'm trying to fix the MBR using Ubuntu live CD. I already have the ms-sys installed but from the threads that I saw, I'm not completely sure in which /dev I should execute the command:
sudo ms-sys --mbr7 /dev/???
(is it mbr7 the correct option when using Windows 7?)
ubuntu@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x1f205b1f
Device Boot Start End Blocks Id System
/dev/sda1 * 38 38 0 0 Empty

/dev/sda4 155854848 625137663 234641408 7 HPFS/NTFS/exFAT
ubuntu@ubuntu:~$
Why is /dev/sda1 empty?
I'm trying to fix the MBR because I'm getting a black screen when trying to load the operating system.
