Window 32 bit to Window 64 bit OS

You will have to run it by booting from the CD (or whatever media you are using) to install.

I tried to boot from the CD but it did not work. Unless I am doing something wrong.

In the BIOS make sure the boot sequence has the dvd drive you are using first although on most systems if a bootable dvd is detected it should say so as its starting up and give you the option to boot from it;

Although this way, doing a clean install would overwrite your files and previous OS so back them up and i would reccommend following a better written guide than mine. :L

I change cd/room to be my first boot however the it did not boot from my CD so I guess I just have a crap disc.

You sure the disc is bootable? If you burnt it yourself then try burning it at a lower speed and using the verify disc option in your burning software to make sure the disc burnt properly.

is it a 64 bit capable computer!

You can not install XP over windows 7 need to do a clean install and boot from the XP cd. Make sure its not a XP upgrade cd or you can not boot and do a clean install

You keep saying CD. Windows 7 is too large for a CD, it is on a DVD. Make sure that you have a CD/DVD drive. If it is only a CD drive, that's the problem.

If you have a CD/DVD drive, download a live CD such as Ubuntu 64-bit, and see if you can boot to it from your CD/DVD drive. If you can then your CD/DVD is okay.

If you don't have a 64-bit computer, the Ubuntu CD will start to load and then tell you that you don't have a 64-bit processor.

If your CD/DVD drive is okay and you have a 64-bit machine, then you need to re-burn Windows 7 to a new DVD.

in the bios set the cd rom drive first in the list!

Sorry if I was not clear. Yesterday, I was building this computer. I temporally installed window 7 32 bit (had no serial key) to see if the system would work. My system is compatible with window 7 professional 64 bit. The new system specs :
i7 930 2.8ghz
Radeon 5870 XFX edition
6gb of DDR3 RAM
500GB harddrive
750 PSU corsair

Is there any other way I could do a clean install?

Boot to the install disc, choose 'Custom Install", and point the installer at the same partition which you currently have windows installed to.

I would do that but it is not happening in windows/nor bios

I think the disc that the school gave me is just a "upgrade" if that is the case I will not be able to use this cd nor serial key. I think I will just buy a OEM verison on neweggs.

Then again I was able to install the 32 bit window 7 when I got the CD from campus last year. ~_~ When try to use the 32 bit pro cd it boot up just fine. (of course I have no reason to install it since it is already on the machine but wanted to check if it was my cd/rom)
