Restore the SAM file from a backup, you can find a backup in one of the
Restore Points "Snapshot" folders inside the System Volume Information
folder. Look for _REGISTRY_MACHINE_SAM , rename it SAM and place it in
the \WINDOWS\system32\config folder. The path to the Snapshot folder
will be something like this:

C:\System Volume
Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}\RP1\Snapshot

Mount the drive in your other computer or use a Bart PE disk. Building
a PE disk can be a bit daunting for some, if you want you can download a
pre-built one instead:

Welcome to the UBCD4Win.com

Note that you need a Windows Installation CD-Rom to complete the
UBCD4Win PE disk, read the FAQ on the web site.
