Upgrading from Windows 7 32-bit to Windows 7 64-bit with a clean install

I have Windows 7 installed (32-bit) and want to upgrade to 64-bit. My PC is 64-bit ready. I have read that to do this I need to do a clean install however when I boot up from the disc drive it says press any key to boot from DVD and when I do it just loads windows normally, it won't load in to do a clean install.

I tried the 32-bit disk and it's doing exactly the same thing, it just won't start the clean install, keeps loading windows as normal. It's a bought original disk. I tried making a bootable usb and run it from there but that didn't work either. Any ideas?

Oh and I'm definately pressing the press any key bit in the time frame.

Can someone help please?

Hello Ben, to Windows 7 Forums,

Is your PC set to boot from CD/DVDrom first? This would be set from in the BIOS under "Boot Priority" devices.
When do insert the installation DVD?

If you have a 64-bit installation disk, and a 64-bit ready computer, there shouldn't be any problems, 32-bit and 64-bit Windows: frequently asked questions

If you don't have the 64-bit disk, I guess you'll have to buy it...
