I have Windows Vista loaded on C: drive. Data files on D: drive. I have Windows 7 OEM System Builder pack and would like to move to Windows 7. Can I leave data on D: drive during Windows 7 OEM Builder pack install....? I understand you select format hard drive during install. Will it only format C: drive or the complete hard drive (C: and D: volumes)...?
