New computer, Windows 7 doesnt boot? -

Hi all, I just bought a new computer and on it, i installed Windows 7 beta 64-bit. However, it freezes every time I reboot the computer. i didn t install any other OS on it. How do i remove it? If possible, i d also like to install vista but whenever setup starts, it tells me the setup encountered an error and I would have to restart to continue... but when I restart, same thing happens... goes in a loop. Could it be my computer?: Gigabyte GA-EP45-UD3R EVGA GTX 280 Intel Core 2 Duo E8400 3.0GHz 1TB WD HDD Corsair TX750W PSU 2GB DDR2 667 (replacing them soon) And a weird LG DVD/CD Reader. It might be the RAM but I also have my suspicions on the DVD reader as I ve never seen it before and my old LG broke down in a few weeks. Any ideas on how to uninstall or install Vista/XP w/o any problems? Thanks! All help is appreciated!

There is not really a way to uninstall Windows 7. The procedure to remove Windows 7 depends on the computer system at hand. Was Windows 7 installed as another operating system in a multi-boot environment or as the only operating system? Is there data on the Windows 7 partition that needs to be backed up because it is still needed? The easiest solution to uninstall Windows 7 would be to simply erase the data on the partition and join that partition again with another one or directly install a new operating system on it. Here is a quick guide what you should consider when uninstalling Windows 7.
