How can I load a registry key when booted from bootdisk

I have accidentally deleted a whole registry key rather than one of its values and as a result i get blue screen whether i try a normal boot, safe mode with command prompt or recovery console (im using win2k server).

I have the registry key that i deleted having got it from another machine and put it into a .reg file. can i use regedit.exe to load the key back into the registry if i boot from boot disks? or have i completed shafted the server and have to do a whole reinstall?
