I'm trying to install windows 7 on a machine that currently has XP Home on it. I have set the DVD drive to be the 1st boot device in the BIOS, but the machine refuses to recognise the installation disk (Genuine copy direct from MS) - it just skips over it and boots straight into XP. Unfortunately the BIOS does not allow for booting from a USB drive so I am a bit stuck.
I gather from reading other threads that it is possible to boot from a Vista installation disk (yes the machine will recognise this installation disk and boot from it) and then at some point substituite the Windows 7 disk to complete the Windows 7 installation. Can anyone tell me how to do this?
Alternatively is there a way to force the machine to boot from the Windows 7 DVD - it won't run from within XP either. I have tried using an XP boot disk to try and run setup from there but it just comes up with a readme file that says that the O/S needs to support ISO-13346 "UDF" file system.
Grateful for any assistance to get Windows 7 on this machine!
