Cant install Windows 7 Ultimate edition 64 bit

Hi there, i know my computer is 64 bit windows compatable. At the moment i have windows 32 bit installed, as my computer crashed and i needed to do a fresh install of windows and installed the 32 bit version by mistake. I have a copy of the 64 bit windows and am trying to install it, however it keeps freezing on computer restart. I put the disk in and it installs all the necassary files, but when it restarts, it hangs on the "windows 7" screen, i just get the white writing on a black background but teh swirly things dont show up and i have to turn it off. What can be causing this as i need to install a 64 bit version so i can run the new preimer pro. (CS6)

Is your 64-bit install disk burned, borrowed, OEM, retail, or what?

Are you booting from that disc?

When you get to the screen that asks "Where do you want to install Windows", are you choosing "drive options, advanced" and then deleting all partitions?

Download a bootable linux disk - like GParted - and format the disc You want to install Windows on.

The disk is a burned copy of windows ultimate edition 64 bit. It doesnt give me the option to delete the partition. Just says refresh drive or load driver

Did you download the ISO to burn the disk from mydigitallife.info??

Or from some other source?

i downloaded the iso from another source

I'd get it from mydigitallife.info---a known good source that gets the ISOs directly from Microsoft.

Reburn it at low speed with a reliable burner such as ImgBurn.

Disconnect external peripherals other than mouse, keyboard, and monitor.

Disconnect all but 1 hard drive.

See if you can get any farther. If necessary, you can wipe the disk using Diskpart, but that's normally not necessary.

In certain cases, it helps to use only 1 stick of RAM, but not normally.

so i need to download this diskpart thing?

No. It's available from the install disk. Hit shift F10 when you come to the language screen and type diskpart at the prompt.

But it's not normally necessary.

You more likely have some other issues.

Can't hurt to use diskpart, but it may not help.
