Background: I have a Dell PC running Vista Business 32bit SP2. The hard drive was partitioned into two roughly equal parts, C: and D: and the C: drive held the operating system. Over the last few years C: has filled up, even though I moved all the file system to D:. I tried to rearrange the partition sizes but wasn't successful, so C: is now full to bursting. I have decided to do a clean reinstall of Vista to get rid of all the clutter on the hard drive, not to mention all the stuff that we have accumulated that we no longer need.
Trouble is I can't find the original Vista disk that came with this pc. I do have a Vista disk from a deceased laptop that I was hoping to use, but it is a Home Premium SP1 version.
Does anyone know for certain whether I can use this alternative disk?
I will be grateful for any informed advice.
