I would like to repair my Windows 7 MBR using Hiren's Boot CD 15.1.

I want to know the generic method, using this CD, to fix an MBR that is hypothetically "toast".

This hypothetical HD is as follows:

  • 100 MB MBR partition
  • 60 GB Windows 7 system

Let's imagine there is an empty 100 MB partition and the MBR is corrupt beyond repair or completely not there and my only option is Hiren's Boot CD.

Hirens has the MbrFix tool.


C:> MbrFix /drive 0 fixmbr /yes

MBRtool is also on the Hirens disc

  • Does this work on UEFI systems? May 27, 2016 at 10:53
  • UEFI does not use a MBR, so no.
