Accessing SQL server database from files on different machine(windows authentication)

pwd

My laptop broke
I'm able to access the internal hard drive, via an external enclosure.
I have not been able to boot from that drive on a different computer as an external disc. It gives a message that winloadexe has incorrect diital signing.
There is a database on the hard disc that I need. However I am pretty sure it is windows authentication, and it was using a local account.
I can rebuild it as I have a recent copy of it elsewhere, and have noted changes/changes will be reflected in program code I've recovered etc. The content is junk test data also.
I'd prefer if there is a reasonably quick way of accessing it directly though; quicker than updating the backup like.
Incidentally, I never realised how easy it is to get at the contents of a windows user account without a password, once you have the disc.

If you can get the MDF file, use sp_attach_db
