Restore Win 7 MBR without Recovery/Install Disc

Download mbrfix from http://www.sysint.no/products/Download/tabid/536/language/en-US/Default.aspx

This is a small, handy CLI tool. Then just run

 ./MbrFix.exe /drive 0 fixmbr /yes

Two ways I can think of.

  1. Use the W7 recovery environment (boot from the Recovery CD/DVD) to execute the fixmbr command

Use another Windows 7 PC to make the recovery disc.

All Programs>Maintenance>Create a System Repair Disc

(2). Make a UBCD bootable flash drive, use one of the MBR tools to backup the original MBR and restore it to the new drive.

UBCD

Run Ultimate Boot CD from your USB memory stick. A script on the CD prepares your USB memory stick so that it can be used on newer machines that supports booting from USB devices. You can access the same tools as you would from the CD version.
