Restore backed up MBR hard drive to UEFI GPT formatted Drive for Win 8

Thread needs solution

I have the 2013 Plus pack and have created a WinPE/Acronis recovery disc.

I have a system that has a UEFI BIOS, but is currently configured with standard MBR formatted hard drive. I would like to convert this system to UEFI/GPT. If I convert the hard drive (reformat) to GPT, will I be able to restore the drive using the Acronis backup from the MBR formatted drive?

First. Be absolutely sure your current backup contains the entire disk image of your current system, and has been validated using the Rescue Media. If you proceed, and can not restore this backup, you will not have a working system!

The answer to your question is, maybe.

You must be running Windows 8 64 bit to be able to boot to a GPT disk.

I have used this procedure, but it is not always successful!

The following instructions will only work if your Windows 8 64 bit system has only the standard partitions created by a clean install of Windows 8 64 bit edition onto an MBR disk. (350MB System Reserved, and your OS partition - if you have a separate DATA only partition that is okay as well.) If your backup includes OEM installed recovery or utility partitions, you may not (probably won't) be successful.

Install the Secure Boot Hotfix for Acronis 2013, and recreate your Rescue Media http://forum.acronis.com/forum/39714 before beginning.

Set your system firmware mode to UEFI (enable Secure Boot if you have this option), and boot to the 2013 Acronis Rescue Media in UEFI Mode.

Use the Acronis tool from the Rescue Media "Add a new disk" to create a new unallocated GPT disk - no partitions are necessary.

Once you have done that, you would need to restore the Windows 8 System Reserved partition first, and be sure it is set to active. Do not exit the bootable Rescue Media after this restore.

Restore the OS partition next.

If you have a DATA partition, you could restore it now as well. (I prefer to do this after getting Windows running again.)

Do not restore the MBR/track 0 or the Disk Signature. Both are not necessary for GPT disks.

After restoring your partitions, shutdown the system. (You can shut down without exiting the boot disk).

Boot to your Windows 8 64 bit installation media, and use the Windows 8 Startup Repair Manager to check and correct any errors it finds. This should create/correct the necessary boot manager entries, and boot files, needed to boot Windows in UEFI mode with a GPT disk.

As I said earlier, this may not work for you depending on your system and existing partition layout.

Thanks, I've given up on UEFI on the particular machine. I've tried installing Win 8 Pro 64 bit and Win 7 Home 64 bit (UEFI) and in both cases on the first reboot I get an error and neither Win 8 or Win 7 can repair it. However, with an MBR formatted disc (the same disc) it works fine.

The Acronis Linux version rescue media disc will boot but all I get is garbage on the screen (i've tried Linux version rescue discs from both 2012 and 2013 and they are the same). I downloaded Ubuntu Linux and created a bootable disc and booted with this on the PC (run Ubuntu from disc) and it works OK. I have a WinPE/Acronis rescue disc and it loads OK and I'm able to backup/restore or run the untilities and either format the drive for MBR or GPT OK.

The error that Win 8 displays is "Your PC needs to be repaired. The OS Couldn't be loaded because the kernal is missing or contains errors. File:\windows\system 32\ntoskrnl.exe Error code 0xc0000221". This happens on the first reboot during the Win 8 install. I let Win 8 delete partitions and then reformat the drive (with the four partitions) and then install. I've also flashed the BIOS and tried several times. The BIOS has an option to "restore UEFI defaults" and I've tried that. I've given up as my thought is there is either a BIOS or motherboard hardware problems.

The PC is one I built. It has a Z77 Professional Fatal1ty motherboard, i5 3550 CPU. 8GB RAM, a 750GB WD hard drive, no expansion cards. It is a backup for my recording studio PC.
