I messed up my system drive's MBR

Thread needs solution

I messed up my system drive's MBR (not badly*) yesterday.  Fortunately, the day before I had created my first ATI image of the full system drive.

I wish to get back my MBR from the image, while not getting back the rest of the image (one partition, "C"), because my image is 2 days old now.  I appears to me that, and I see how, the Boot Media's Recovery Wizard allows me to do this.  And from the manual, it appears that I want to also check "Recover disk signature".

Does my plan sound proper?  (Forgive me for asking--I was tempted to go ahead and do it--but MBR and disk signature are mysterious to me, so could someone let me know if my plan is a bad one? 

Incidentally, after this I will create my first Incremental, then promptly swap in a New HDD for this system drive then do a full restore to it.

*I installed grub4dos which, just after the BIOS on system boot, briefly displays a screen/pauses to look for a file called "grldr" (after a couple seconds the boot proceeds AOK since the file isn't there).  I was trying to make a USB bootable USB stick.  I mistakenly modified the MBR of my system drive instead.

Coyote, if you boot from the rescue media and follow the process to restore your disk, you can then select to just restore the MBR and Track 0, plus you can recover the disk signature.

MBR = Master Boot Record which for Legacy / BIOS systems contains the details of how the computer will boot the Windows OS.

The Disk Signature is often referenced for the purpose of software / application activation, i.e. for such as MS Office.

Thank you very much for your reassuring reply, Steve!

Yes I saw those boot media restore options; I'll go ahead and use them.  Sorry I wasn't confident enough not to bother you good folks!

Wow, that MBR restore couldn't have been easier, quicker, or more successful!  Thank you again, Steve!

Glad to hear your good news, thanks again for giving feedback.
