Hi:

See if this works...this is how you do it on the 8200 Elite...

After entering BIOS Setup by hitting the F10 key, press Ctrl+A to open additional fields in Security>System IDs menu.

Enter your PC's serial number in Asset Tag Number and Chassis Serial Number fields.

Save changes there and again when you exit the BIOS.

I know , when i do that , The UUID is Fixed , Can't be changed , is it like the bios is locked or what ?

Unfortunately, I would have no idea.

I was able to change the serial number using that method on my 8200 Elite CMT with no problem.

I replaced the motherboard and wanted to change the serial number on the used motherboard with the one on my PC's case.
