This is most likely a failure of the hard drive - and probably doesn't relate to the software installation/removal problems.
A lightning strike can easily destroy most of the components inside the case.
My last lightning strike at home cost me NIC cards, memory, and a TV card. All systems were protected with surge protectors.
My last lightning strike at the wife's office was a "double strike". The first strike blew most of the surge protectors and the second strike took out the systems. I lost several NIC cards, a cable modem, a router, and a hard drive.
FWIW - the lightning can strike through the cable/network connection as easily as the power connection.
The problem here is that you don't know exactly what was fried by the lightning strike. Although the hard drive may be "toast", you could also have lost other components - and this makes the troubleshooting a very frustrating thing to do.
I'd suggest still trying to recover the data from the hard drive (according to my post above). If the hard drive is bad, then you'll have to reinstall Windows on a new hard drive in order to start troubleshooting the system.
You can test your RAM without a hard drive using this free utility: http://www.memtest86.com/
Just read the directions carefully, then run the test for at least 2 hours (overnight is better). If you start getting errors, you can stop the test and start shopping for memory
