    EFI vs BIOS

    I was reading
    Windows 7: Backup Complete Computer - Create an Image Backup
    http://www.sevenforums.com/tutorials...ge-backup.html

    One section has
    “A system image that was created on a computer using EFI cannot be restored on a computer using BIOS”
    What is EFI and how will I know if the computer is using EFI?
    Is creating a system image backup on a computer using EFI use the same procedure as a computer using BIOS?

    Comtrgy,

    Unified Extensible Firmware Interface.

    Basically, YES! Now it would be helpful if you use a product that supports Booting of the recovery media using UEFI/Safe Boot, which requires different software on the boot media, as does my favorite Macrium Reflect.

    Macrium Reflect is also my favorite and it's good to know it does that too. Thanks RG

    There is no difference in the creation or restore of a backup, it's booting to the recovery media which may present a problem. If you have MBR boot recovery media and a working EFI disk the computer may not recognise the recovery media as bootable without you making changes to the mobo config, aka BIOS set up.

    cheers, Paul

    cmptrgy - Make sure it's the latest version of Macrium Reflect. My MR USB flash disk failed to boot in a brand new HP laptop. I had to download the latest version of MR to a UEFI-based device and re-create the USB flash disk for it to work with this UEFI-based HP laptop. It seems obvious now but it was a bit of a headscratcher at the time because my MR boot ddisk had been so reliable up to this point.

    I'm going to be buying a Windows 10 laptop shortly. It wouldn't surprise me if it will have UEFI with GPT partitioning. I'm not a hardware person so I hope I'm explaining that right.
    --- I will also want to buy an external hard drive for system image backups
    --- How do I determine what kind of an external hard drive to use to do UEFI/GPT system image backups?

    I do have a WD My Passport Ultra external hard drive I use for my BIOS Legacy/MBR systems but it appears to me it might not be the correct one to backup my Win10 laptop

    cmptrgy,

    You're mixing Apples (UEFI) and Oranges (GPT). GPT is a disk partitioning scheme which is an improvement on the old MBR scheme. Windows 10 supports both and when connected via USB you should easily be able to backup to both. I currently backup to both GPT and MBR (WD Passports also) using Macrium Reflect w/o issue.

    UEFI on the other hand is a replacement for the old BIOS firmware standards.

    Your existing WD Passport will work fine with your new hardware.

    cheers, Paul
