I want to do a clean install of 7-Pro 32 upgrade into unpartitioned space on an XP machine, to dual-boot XP and Windows 7. I've done that successfully on a notebook by booting off the upgrade DVD. Unfortunately on this desktop machine the BIOS will not recognize the boot block on the DVD.
If I run Windows 7 setup from XP it does not give the option to create a new partition for the Windows 7 installation, and IIRC, even if I used XP to create a new partition, the XP partition would appear as C: in the Windows 7 installation, with the Windows 7 partition being assigned a new drive letter (is this correct?).
Is there a way to force Setup to install Windows 7 to a new partition as C: even if it is started under XP?
