Windows 7: How Can I Overwrite Drive With Win 7 32 bit to 64 bit

How Can I Overwrite Drive With Win 7 32 bit to 64 bit

I've got a single hard drive with WIN 7 32 bit RC operating OK.
I want to replace it with WIN 7 64 bit RC (not dual boot).

I inserted the 64 bit DVD WIN 7 install ISO disk in my DVD and either it will boot me into by 32 bit system or gives me options to repair it. But, no options to overwrite the current OS.

If I fully boot into the 32 bit edition and try to open setup.exe on the 64 bit DVD it sees a 32 bit system and will not open the 64 bit install program.

How can install the 64 bit OS over the current 64 bit OS

You cant update to x64 from x84.
You have to perform clean installation.
Are you sure that your system supports 64bit?

Yes, my system has an AMD 64 bit processor.

I do want to do a clean install but I can't figure out how to do it. I'm not trying to update.

I insert the 64 bit WIN 7 RC DVD and boot to it but I don't see any options to overwrite the current drive? How do I do a clean install ??

Have a look at this Clean Install Windows 7
You need to select custom install then point to the the drive where you want it installing on.

Thanks. I got it working.
I think my problem was that I didn't press "any key within the 8 second time frame" (as noted in the instructions) and it booted into the previously installed version rather than from the DVD. I just hesitated too long because I was trying to read the screen so I would not screw up. How is that for irony!

Will XP overwrite my 7 bootloader if it's on a separate hard drive?
This might sound stupid, but if I dual boot with Windows 7 on a physically separate hard drive, as well as XP, will XP still override my Windows 7 bootloader since it tends to get jealous? :p
