I am currently installing a copy of windows 7 upgrade on a REFORMATTED hard drive.
I had not realised that the installation requires a current version of XP on the machine so went ahead with the installation. (http://windows.microsoft.com/en-us/windows7/Windows-7-activation-error-invalid-product-key
I get all the way through but it rejects the product key and locks up. I can't reverse the installation nor go forward.
TRying to boot from XP disk doesn't work. I also tried booting from 'ultimate boot CD', but I just get back into the windows 7 partial installation.
How can I uninstall the win 7 at this stage?
Reformat the drive?? -- there is a stage in the process where i can access a command prompt which seems to be assigned as drive x: -- Can i reformat the disk from there using dos commands?
would it be feasible to try booting from dban http://www.dban.org/about
?? (I DO get the boot from disk option while booting up, but it just goes back to win 7, even with XP or UBD in the drive). (note that the machine only has a dvd drive - could this be significant?)
I would appreciate guidance and any other suggestions before I have to take the drive out and reformat it on another computer (I just did that as part of the repair on the drive !!)
