[OneDarkLord]

According to Post # 5 by gregrocker in a previous Forum thread, you cannot upgrade from a 32-bit OS to a 64-bit OS. It must be a clean install. However, the same Product Key can be used for either the 32-bit OS or the 64-bit OS if they are the same version (Pro to Pro, Ultimate to Ultimate, but not Pro to Ultimate.)

^100% correct. Unfortunately, you must do a clean install of Windows 7 to go from 32 to 64 bit.

I have OEM (COA) product key,from what i read it can be used only on 1 PC,so how to deactivate it before installing the 64bit OS?

There shouldn't be any issue because it's the same OS just a different bit-ness. But if it doesn't activate you will have an option to use the telephone activation method.

Describe the steps you have followed so far.

None,too much to read lol,i just want to replace my 32bit OS with 64bit,i don't want to backup any files,i got nothing important on the PC.

In the BIOS i choose to boot from the Flash USB that contains the 64bit OS but i get error.

So, you can't be arsed reading the tutorial because "its too much reading", and then expect me to hold your hand and guess what problems are happening with the installer?

Try burning ISO to DVD, and start again.

Is my USB required to be NTFS?
Currently it's FAT32
