I've searched and couldn't find a really good satisfactory answer to this.
Basically, I don't have a way of backing up my data. I've got two HDs, but both are almost full, and both have important things on them. There's enough space in the main drive to create a new partition. So here's what I'm wondering:
1. Can I just create a new partition on the main drive and install a new OS (e.g. Vista 64, which I have a disc for) without losing the rest of the data on the drive?
2. Right now the OS is (I'm sure) an OEM version. if I install a new motherboard and processor (into a new case with new PS) will my old XP OS even boot?
2. The OEM OS will install but you won't be able to activate it.
Can you grab a USB External storage and move the important stuff? Also if you don't have an externel drive I highly recommend you get one and start backing up your data to that (unless you already back up).
