View Full Version : [SOLVED] Accidental MBR erase, now need to restore it
September 20th, 2009, 02:56 AM
I had win 7 + ubuntu 9.04 and I accidentally erased mbr, forgetting that it'd kind of kill the partition table. how would i restore it? I really need to have it back up by midnight (5 hours).
There are about 8 or 9 partitions there.
Thanks for any help.

It depends which MBR you want to reinstall - If your most urgent need is a working system, you need one of two things: an Ubuntu Live disk or a disk with Windows 7 on it.
With a Linux LiveCD you should be able to either pull GRUB up and fix the MBR or fix the MBR manually (much more advanced, I can't guide on that!).
If you have or can burn one, a Super Grub Disk from http://www.supergrubdisk.org/ will let you re-write GRUB into the MBR and should re-write the MBR. You could re-write a Windows MBR but it won't let you access your Linux partition then.
With Super Grub disk, try to autofix or boot without the MBR being recovered, then if you have a backup you can restore from it or at least get what you need done. Not sure if this helps, but I hope it does!

Ah, it got marked resolved between my opening it and replying. Glad to see you're getting help on it! Good luck, and SuperGrubDisk has saved my bacon a number of times, hope it does well for you. That or TestDisk as someone else mentioned.
