Error message when using Windows 2008 R2 Windows Backup to perform Full Restore "The system image was created on a computer using EFI and the computer is using Bios"

Posted on 2012-08-23

We have a 2008 R2 Domain Controller (IBM x3400 M3) and we're using the built-in Windows Backup to perform a Full Server Backup to an external hard drive.  We're trying to restore the Full Server Backup from the external hard drive to a server (IBM eSeries x226) in our test environment.  We boot from the Windows 2008 R2 DVD and select the System Restore option.  When we click next we receive the following messge:

"The system image was created on a computer using EFI and the computer is using Bios"

Can someone please help us determine what might be causing this message to appear and how to correct the issue?  We'd like to test a "bare metal restore" to another server (with different hardware) in the event of a server "crash".  Any advice would be great.

    So it appears we're getting the opposite error message than the example in the link:

    Ours = "The system image was created on a computer using EFI and the computer is using Bios"
    Example =  "The system image was created on a computer using BIOS and the computer is using EFI"

    I confirmed the Production server is using an EFI Partition (see attached file).  I'm assuming the test server does not have an EFI Partition configured. (Also, in the example they're using the same server hardware type.  We have different hardware types)

    Would it be possible to create an EFI Partition on the "test" server?  If so, any advice on how this could be accomplished?  Thanks

    The problem is not related to GPT vs. MBR-style partitioning - instead, the new server appears to have a traditional 16-bit BIOS (like the original IBM PC), while the old one had a 32 or 64-bit EFI. However, I find it unlikely that a server nowadays would come with a traditional BIOS (even consumer desktops and notebooks come with EFI these days, though it is often made to masquerade as a traditional BIOS to the user) - look in the BIOS setup for an option like "EFI Boot" or "UEFI Boot", and enable it on the new server.

    Also, make sure you are using a Windows Server 2008 R2 DVD that actually supports EFI booting - many tools used for customizing installation media destroy the EFI boot sector of the DVD image.

    The older server we were trying to restore to didn't have the option for EFI Boot or UEFI Boot so we performed the restore on a newer similar IBM server (once one became available after a decom) and we received successful results.  Thanks for the feedback and info.
