I have windows xp 32 bit OEM that came pre installed with a dell computer 4-5 years ago. I now want to upgrade to windows 7 professional 64 bit. What I want to know is can I use the upgrade edition to do this?
I am aware that I will need to do a clean install for this. My second question is will I be able to do this install on to a different hard drive? obviously I don't really want to be relying on such an old hdd and would have long ago gotten rid of it if it wasn't my only copy of windows.
To summarise my questions:
-Can I use the upgrade edition to go from win xp 32 bit OEM to win 7 pro 64 bit?
-Can I install the upgrade edition on a different HDD than my previous installation on windows?
Yes, and Yes. You can purchase and install Windows 7 with an upgrade disk if you own a previous version of Windows all the way back to Windows 2000. You can also do a clean install with the disk. Link to a guide on doing that install in number 16 of this thread.
