This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Your "actual problem" involves an operating system bootstrapping to the point where it is maintaining a mouse sprite. That's well past the stage of running the bootstrap program in the MBR. What is your evidence that you need to do anything at all to your MBR contents? – JdeBP Dec 31 '11 at 20:00
the suggestion of a friend. Please comment on the other question if you can help – Adam Lynch Dec 31 '11 at 20:46
Your friend is suggesting things at random, without any understanding of what your computer is doing. You've invoked Microsoft's Boot Manager and from it bootstrapped an operating system at least five times. The bootstrap code in your MBR has done its job each time and is in no need of restoration. – JdeBP Dec 31 '11 at 23:49

You will need access to a system that has a DVD burner to start.

Have not had to try this procedure myself, but give this a try and let us know what happens.

I have done this while trying to fix it other ways but this doesn't show me how to restore the MBR! It just shows me how to create a Win7 recovery USB – Adam Lynch Dec 31 '11 at 18:21
@AdamLynch: A recovery USB has the capability to restore the MBR. – surfasb Dec 31 '11 at 18:22
@surfasb How? Are you saying it is the same procedure as the link I provided? – Adam Lynch Dec 31 '11 at 18:24
@AdamLynch: When you boot using the USB drive, you can then select repair my computer, or go into the recovery console and type bootsect /fixmbr. – surfasb Dec 31 '11 at 18:31
@surfasb The first one doesn't work before now. I'll try "bootsect /fixmbr". I thought it would be a lot more complicated; the link I provided seemed so – Adam Lynch Dec 31 '11 at 18:33

If all else fails, and you're sure it's the MBR, you can use Testdisk to write a new MBR to the drive.

The Testdisk MBR is not the same a a standard MBR, but it should allow you to boot from any partition whose boot sector is valid.

Testdisk can also repair damaged partition tables, boot sectors, and other volume structures.

Testdisk can be run from a Live Linux CD/USB.
