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

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

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. Can someone help please?

Windows 7 Home Premium SP1, 64-bit

Did you make a change in BIOS settings to boot from DVD first?

Can you boot from the 32-bit disk as if you were going to do a clean install of 32-bit?

Can you boot from any other known bootable disk?

Is the disk a burned disk or a purchased disk or a borrowed disk or ???

Make it sure that you are pressing any key within the time the text is shown .

If still the situation is just the same , do as suggest, try with another installation media.

Windows 7 Home Premium 32bit

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.

Windows 7 Ultimate x64

Did you change your first boot device to DVD-Drive or USB?

Generally, if the DVD or USB does not work properly (e.g. is not bootable), it will just skip and go to the next bootable device, which in your case is your hard drive.

Reset your BIOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

Set HD to boot first in BIOS setup, then tap the one-time BIOS Boot Menu key to trigger the DVD.

If this fails write official ISO to flash stick using Universal USB Installer with Win7 in dropdown menu. Boot it also using the BIOS Boot menu key.

Why would you not at least tell us your computer model, as we could then tell you the key to press?
