    Bootable Win10 USB Doesn't Work on ASUS H97-PLUS Motherboard


    I'm running Windows 10 22H2 on two different desktop computers. I make a backup image of drive C in each computer, using AOMEI Backupper Standard. As detailed elsewhere, I restore those images to two Samsung thumb drives (MUF-128AB FIT Plus 128GB USB 3.1).

    As established in many prior instances, each of these two USB drives is able to boot Windows 10 on various laptops. Yet when I try them on the older of the two desktops, using an ASUS H97-PLUS motherboard, neither is able to boot Win10. This is not new: I'm not sure that desktop has ever been able to boot Win10 from USB. It is however able to boot Ubuntu from USB.

    A person would think this must just be a BIOS problem. Yet I have gone over the BIOS settings recommended by various sources ad nauseum, and unfortunately I just cannot find the problem. Does anyone know of any specific issue with that motherboard, or any combination of BIOS settings that maybe I haven't tried yet?

    You must boot the USB drive the same way (UEFI-GPT or Legacy-MBR) the original drive was. Was the original drive UEFI-GPT or Legacy-MBR?
    During POST, press F12 to launch the boot menu. You will see two options for the USB drive. USB UEFI (Name) and USB (Name). Select USB UEFI (Name) if you want to boot as UEFI-GPT or select USB (name) if you want to boot as Legacy-MBR.

    Thanks for your replies. As I say, I seem to have tried all possible settings. I am plainly able to figure out the solution on the other computers that do boot from those USB drives. There appears to be some complexity, some incomprehensible interaction among settings, in that particular BIOS. It's AMI 2.16.1240, from 2015, on an ASUS H97-PLUS motherboard.

    You won't be able to boot from the USB drive if it is a legacy-MBR and you're trying to boot as UEFI-GPT or if it is a UEFI-GPT and you're trying to boot as legacy-MBR.

    This is incorrect as the AOMEI recovery is a WinPE based iso and universal i.e. will boot on a legacy bios pc or a uefi pc.

    My laptop is UEFI only but the AOMEI usb is stored on a fat 32 mbr formatted drive and boots fine.


    If drive is failing to boot on an older device, it is probably due to a missing driver. OP would need to add the driver to the usb flash drive.

    The easiest way to do this is to Install AOMEI on old pc and create flash drive from the old pc, then it should pick up drivers it needs.

    Here's a blow-by-blow description of the process, refining what I said earlier.

    I make an AOMEI image of the Windows 10 Pro (22H2) installation contained on drive C on the computer that uses the ASUS H97-PLUS motherboard (referred to, here, as the ASUS computer). Drive C is on a Samsung 850 EVO M.2 (SATA III) drive, GPT-partitioned into a 518MB recovery partition (NTFS), a 91MB ESP partition (FAT32), and a 159GB drive C partition (NTFS). AOMEI saves that image in a 61GB .adi file.

    I use AOMEI to restore that ADI image to a Samsung MUF-128AB FIT Plus USB drive, unformatted, partitioned as GPT, with SSD alignment. I am using the free AOMEI Backupper Standard, so I don't have the Universal Restore feature available in Backupper Pro. This restore is a slow process, taking the better part of three hours. The resulting USB drive - what I refer to, not altogether correctly, as a Windows To Go (WTG) drive - now has 10.6GB of free space remaining, out of 118GB originally available.

    I have configured the ASUS machine to display bootup details. I hit F2 during bootup - when an ASUS splash screen would normally appear - to get into the BIOS/UEFI settings. I set the BIOS to ignore the M.2 drive. (In BIOS, this setting is at Advanced > PCH Storage Configuration > SATA (SATA 5,6) and M.2 Configuration > SATA.) To test the USB drive that I have just created, I verify that other settings are configured as follows:

    Boot > CSM > Launch CSM > Enabled >
    Boot Device Control = UEFI only
    Boot from Storage Devices = UEFI driver first

    Boot > Secure Boot > OS Type = Other OS

    Then, with the newly created USB drive plugged into a SATA port on the ASUS computer, I hit F10 > Save Changes & Reset > Enter. I see the black-and-blue Windows 10 logo. The system does appear to be trying to load the OS on the USB drive - slowly. This process ends with a BSOD:

    Your device ran into a problem and needs to restart. You can restart.

    For more information about this issue and possible fixes, visit Resolving Blue Screen errors in Windows - Microsoft Support

    If you call a support person, give them this info:
    Stop code: INACCESSIBLE BOOT DEVICE
    The result is the same if OS Type is set to "Windows UEFI mode" instead of "Other OS." An attempt to repair the USB drive using Boot Repair Disk is unsuccessful.

    This USB drive does successfully boot a different computer.

    So my question is whether I am overlooking some other setting, among the many settings in this BIOS setup utility, or whether there is some workable fix.

    I think you didn't understand what OP wrote on post #1, and it's in English, you natural language.
    OP isn't trying to boot a AOMEI Backupper drive. He is trying to boot a USB drive that had an image applied with AOMEI Backupper.

    No need to be sarcastic.

    In the end, the same issue is almost certainly driver related. Creating WTG drives on old devices is not straight forward.

    I created the WTG on a new ASUS Prime H770-PLUS D4 LGA 1700 ATX motherboard. So that's not the problem.
