How to clean an MBR and recover drive partitions

Sometimes it’s necessary to recover drive partitions because you accidentally repartitioned a drive you didn’t mean to, or because your MBR got infected or otherwise trashed. Here’s how to recover them, for free.

Infecting MBRs with malware is popular with virus writers again. And I fully expect chaos to ensue, because that’s what happened the last time there was more than one virus floating around that infected MBRs. They quit doing it for a good reason.

So here’s how to clean up the mess when an MBR gets infected, or when multiple infections blitzes the MBR and the hard drive loses the ability to boot, just displaying a message like Missing Operating System or Operating System Not Found.

It’s not a substitute for normal antivirus software–it’s what you call on if and when normal antivirus software fails and a malware infestation prevents normal use of the computer.

Here’s how I removed it for someone.
