Help, Need To Downgrade from Windows 7 Ultimate 32bit to W7 Pro 64bit
I bought a refurbished Lenovo T400 with a 120gig HD and Windows 7 Pro 64bit OS about 6 months ago. A week ago the HD died so I had a knowledgeable friend of mine replace the HD and he replaced the software with Windows 7 Ultimate 32bit OS without asking. And now the laptop does not function near as well as it did before.
The guy I bought the laptop from gave me a copy of Windows 7 Pro 64bit.
How do I get rid of W 7 Ultimate 32bit and replace it with the software I had originally, Windows 7 Pro 64bit??
Thanks you friend for helping in advance....
