Install Windows 8 64-bit over the top of Windows 8 32-bit
I currently have Windows 8 32-bit installed from MSDN (I didn't realise at the time that my processor supports 64-bit).
I understand that you can't upgrade within Windows 32-bit to 64-bit directly from the ISO.
I have burned the ISO to a DVD, and have attempted booting from this drive.
The problem I am encountering:
The operating system couldn't be loaded because a required file is missing or contains errors.
File: CI.dll
Error code: 0xc0000221
You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.
Additional info:
- Computer: HP Pavillion m9280.uk-a
- Processor: AMD Phenom 9600 Quad-Core
- RAM: 3 1GB sticks
Thanks in advance!

You might want to boot from a Linux rescue CD and scan the drive for malware because it may be down to something like this.
Alan BDownload GParted, burn the LiveCD (or create a LiveUSB), then boot from it and repartition/format your HDD as required. Now boot from the Windows 8 DVD (or USB, which is much faster) and proceed with the installation. If you still get the error, recreate the install media from a known good source.
KaranRight, so understanding that you used the Windows 7 USB/DVD Download Tool on a 32-bit PC to create a bootable disk for a 64-bit ISO, first of all you would have got an error at the end of the burning process saying that the bootable disk couldn't be created. To fix this problem, follow the steps listed on this site http://kyleabaker.com/2011/12/29/create-a-bootable-windows-7-x64-install-flash-drive-from-32-bit-window/
I can vouch for this site that the solution given here works because I had the exact same problem. Hope it helps.
