Can you contact your installing branch and see if they have a record?

Can you find the disk case for the I/Net system? The code is printed on there. The certificate will have it also.

Will you be reloading the original OS? If not, check the compatibility with your version.

Without the case, certificate or branch help I'm not seeing many other options.

Good luck!
