Could someone please clarify how I can do a clean install of Vista. Can I
purchase an Upgrade version or do I have to purchase a full Retail copy to
enable me to do a clean install. I have always purchased the Upgrade copy
of
previous Windows versions but this time things seem to be different. Help
please.
Vista's upgrade process is different in several respects. Assuming you mean
upgrading from XP x86 to Vista x86, XP must be installed, activated and
genuine. If you plan to do an in place upgrade - to carry over data and
programs, then XP must also be at the SP2 level. The upgrade is started
from the XP desktop. You can choose to do either the in place upgrade or a
custom install. A custom install is similar to a clean install. Neither
data nor programs are carried over, what was on the old installation is
archived in a windows.old directory. This data is set aside, and a fresh
image of Vista is laid down. It's not a file by file copy but an image, so
it is in that sense a clean install. The archived data is then moved to the
windows.old folder.
If you don't want to start from XP being installed, then buy a full version
of Vista. Note, depending on what version of XP you're upgrading and to
what version of Vista, the in place upgrade may not be possible, the only
choice might be the custom install.
For a custom install use Vista's Windows Easy Transfer program (WET) to
transfer data and settings from your old installation, and install
applications clean from their original media.
