I've been having problems with my original Seagate 100gb hard disk; it was causing blue screens and also nearly out of space.
I bought a new 2TB (tb, not gb... thanks for spotting it) SSD/HDD hybrid from seagate. P{lugged it in; used the Seagate utility to copy the partitions of the original disk over. So far so good. I then disconnected the old disk and started up. All was fine for a day or so, but I've just got a message saying my copy of Windows may be invalid or counterfeit - I'm assuming it was keyed somehow on the original hard disk. What can I do to address this, short of buying another copy of Windows?
