"Where are you getting Windows 7?" I bought and downloaded the full retail version (not upgrade) from Microsoft over a year ago. Never installed it because I found out MS does not allow programs to be transferred from Vista Home Premium to Win 7 Pro. Recently, I found a program, PCMover, that is supposed to do that so am now trying to install Win 7. (MS can't help me without the order number which I no longer have or can't find.)
"You should have the option to download an ISO file..." To be honest, I did not then know about ISO files (and obviously still don't know how to use them as I cannot get memtest86+.iso to create a bootable CD in spite of the clear and simple directions on how to do so).
"Then boot it to Clean Install Windows 7.
" A Win 7 "custom install" has an option to format the target drive that I intended to use but have to get the downloaded files expanded first.
As I said in my original post, "Numerous posts suggest checking RAM with memtest86." as defective RAM can prevent Win 7 files from being expanded. So my immediate problem is how to make the CD with memtest86+ bootable. Unzipping the memtest86+.iso.zip file was supposed to do that (at least as I understood the directions).
Still have two problems but am tackling 'how to make memtest86+ CD bootable' first.
BTW - Even if I get Win 7 installed, I have reservations about the PCMover program as it's "moving van" file is miniscule compared to the size of the original programs, settings, and data files. I have a Ghost image of the C: drive made before I started all this. Have restored from it successfully so I can always fall back on that.
