    Right click and select "run as administrator"
    The host computer that I am doing it on has crashed.
    I open CMD (and later the USB drive) through the Windows Boot Repair menu.

    And what I can see from the BAT files that Kyhi provides it checks that you have Admin priviliges.

    That batch file adds a boot entry to the bcd used for booting windows. Why do you need to do that. It is only necessary if you store the recovery disk files on a hard disk partition. If you put the files on a usb flash drive, you just boot fron usb flash drive.

    Hmm okay, I thought I needed to do that because I can't see the USB in the boot menu. I've booted other programs with same USB drive without any issues (but none have sold my issues)
    When rebooting the computer I press F12 for boot menu but I can't see the USB-drive.


    EDIT:
    Managed to find it. Changed some BIOS settings. I now go another error: "Selected boot device failed."

    When Using F12 Boot Menu
    You may be presented with the USB device and a UEFI USB device
    You will need to select the Boot Option that will Boot the UEFI Decive

    I was advised to use your recovery tool to sort out my laptop; unfortunately I'm failing at the first hurdle.

    I used Rufus to write the x64 version using GPT for UEFI and FAT32 format. I disabled secureboot on my laptop but I just can't seem to boot from the USB. I've tried two different USBs.

    The screen stays on the Acer loading page for about 3 minutes, then the screen flashes light blue once and goes black.

    I'm sure I'm overlooking something quite simple, but I just don't know what it could be.

    Kyhi doesn't, in post #25 he said...
    I usually just copy and paste the files from ISO to USB..
    My USB's are usually set (marked) as Active and formatted Fat32 (for UEFI and Legacy Support)
    And I never, ever have used Rufus

    Oh! Thank you for this. I'll find out how to mark my USB as active and just copy the files within the ISO over.

    ETA: just tried using diskpart to make my USB active but it said it needs to be MBR to be marked active. I thought UEFI didn't need an MBR, which is for BIOS? It's formatted to FAT32.

    Diskpart is what I and others use. See here for example...
    How do you reset a USB flash drive back to factory settings?

    Thank you for the URL. I didn't realise I had to use the convert MBR command. With that I managed to make the USB active and copied the contents of the ISO over. Unfortunately I am still unable to boot to it in UEFI. In legacy mode I get as far as the screen with the W10 logo before going blank.

    The convert command is not always necessary, but worth using as insurance. The USB you have now made should be bootable on any machine, uefi or legacy, so it looks like the problem lies elsewhere.
