How to recover Win7 Pro upgrade from Win7 Home Premium post HDD crash
Greetings -
This is my first time here and am very thankful for this great collection of forums and this community.
I am trying to recover from a VAIO laptop HDD crash to Win7 Professional upgrade. I had finished working, shutdown Win7 Pro. cleanly. Drove home, attempted to launch Windows and could not, not in Safe Mode either. I restarted with F12 to launch Recovery Mode and it would only get to about 80% and reboot with a drive error (0xE.....9 - I've forgotten the exact code and can put this old drive in and get it if required).
I've done the following:
- Bought laptop with Win7 Home Premium
- Purchased and install Win7 Professional
- Installed VS2010
- Did a whole lot of work for ~2 years
- Original drive crashed
- Replace old 640GB HDD with 500GB HDD
- Downloded and installed Win7 Home Premium using original key
- Started catching (again) with a few hundred Win7 updates
My question to the community and/or any experts is - how do I install the upgrade to Win7 Professional without having to pay Microsoft again?
Any assistance would be greatly appreciated and thank you in advance.
Regards
