I have three HDDs, C: 500GBs D: 80GBs E: 250GBs. I previously had Vista running in the drive with 250Gbs. At that point it was labeled my C drive. So I went through numerous formattings to get my largest HDD to be the C drive. Now that I have the letters in order, I would like to remove the old 250GB HDD and give it to a friend, but When I try to format Windows 7 tells me I cannot. I have both HDDs with Win 7, the D drive is just for storage. Now I know that If I try to just remove the Disk, my Win 7 will not Boot, since I guess the BCD is stored in my 250GB HDD. Is there Anyway out of this predicament?
