Windows 7 ISO file on xp? -

OK i have windows 7 on a disk as an iso file. If i were to install it on the computer when booting will there be anyway i can revert back to xp without the disk.

No. You will need an XP cd to reinstall XP once the beta expires in August unless you dual boot (partition your hard drive) or install W7 to a separate hard drive while keeping your XP install intact. I am dual booting XP and W7. XP is on my master drive and W7 is on my slave drive.

I would use some imaging software such as Norton Ghost to make an image of your current installation on an external USB drive so you can restore XP. If you don t set up to dual boot you will not be able to downgrade back to XP without your disk and license key unless you make an image of your HD as it is now.

Yes, burn the ISO file to a blank DVD. I use DeepBurner Free for that. Boot the PC with the Windows 7 disc in and it should load from the disc and take you through the installation. You can then partition your hard drive so you can have both operating systems. If you don t want to use W7 again then delete the partition in XP and use fixmbr to revert the bootloader back to normal.

Well ive just installed windows 7 - And I made sure I had my Vista CD and product key before installing. Because I thought I would need them to re-install Vista afterwards.
