Geek, here is the problem as I understand it. The hard drive (the original 80GB) is beginning to fail. It will not defrag, it is making a lot of weird noises and Macrium Reflect can not make an image of it. So, when I install the new hard drive I have to do a clean install of Win 7. I have copied/pasted all of her docs/files onto an external hard drive. She does not have recovery disks. I have an OEM Win 7 w/SP1 disk I used on my PC to upgrade from XP. I have not personally checked yet, but I assume she has a valid COA Product Key from the original purchase. With this valid Product Key, I can download an ISO image of Win7 and burn it onto a DVD for install. I just hate to spend $10 for a pack of 10 DVD's, 9 of which will never get used. That is why I asked if I could use my OEM disk with her original Product Key to get Win 7 installed and legally activated. Seems like this should be easy to do and very acceptable to MS. There may be other things wrong with her rig but it seems to be working fine except for the failing hard drive. Right or wrong, she feels like spending $60 to keep her PC going is worth it, even if only for another 6-12 months.
