    I don't know what to say... the computer is certainly doing something odd.

    Sorry if I have confused things, but to be clear,
    The Kingston is not the USB with the boot media - it is the stick I used to save the screenshots to.
    The SanDisk is the drive with the OS.
    The boot media is on the Lexar stick.

    I don't know why the Lexar is not showing up as Drive Y - there is no drive Y shown in File Explorer, just drive X. The Lexar is also not showing up on Disk Management - again, I do not know why.

    I took a few more pics of Disk Management and File Explorer without the Kingston drive and the DVD drive empty. As you can see, there is no drive Y and I don't see the Lexar in Disk Management.

    So Disk 1 (the SanDisk with the Windows 7 installation) shows an EFI system partition, but you say there are no active partitions shown. Is that part of the problem?

    For an efi installation you won't usually have a partition marked active.

    I don't know why the Lexar is not showing up as Drive Y - there is no drive Y shown in File Explorer, just drive X. The Lexar is also not showing up on Disk Management
    Are you using a usb2 or usb3 port ? The media does contain usb3 drivers, but they might not be the correct ones for your machine.

    Try the boot media usb stick in a usb2 port.

    Okay - that makes a difference! I believe that was the problem - I now have the USB booted from a USB2 port.

    DiskGenius seems to have identified problems with the GPT on the SanDisk. I haven't done anything yet - hoping you can let me know the best way to proceed.

    Note: I imagine you can ignore the removable drives shown in Disk Management - they're all from a memory card reader.

    If you need any of the files on that gpt disk, copy them somewhere else, just in case of cock up. Looks like you have space on disk2.

    Then tell diskgenius to correct the problem. After diskgenius has tried the correction, you probably need to click Save All at top left

    Thanks so much - the repair worked! No obvious issues with the system as far as I can see.

    Any idea what would cause such a problem? There were no issues when I shutdown the computer the other day, but the very next it didn't boot...

    Be obliged if you would test these two to see if they work on your usb3 ports

    Not sure what happened...

    I was getting some different messages when I launched Usb7ice, but was able to ignore them and copy the 17514x64v32 ISO to the USB stick. However, when I rebooted, the USB was not shown as an option in the Boot Menu.

    I booted back into Windows and the light on USB stick started flashing continuously as though it were being written to or reading from. The graphics started slowing down and behaving a bit erratic. I was unable to eject the USB drive without shutting down the computer.

    I used FAT32 as I did with the previous ISO.

    Don't know. maybe your usb stick has given up the ghost. They are not very reliable.

    I tried copying the 17514x64v32 ISO to the USB stick again - this time on my laptop with Windows 10. It copied without any issues.

    Again, the USB did not show up in the Boot Menu of my Windows 7 machine when inserted into the USB3 port. I was still able to boot from a USB2 port and for what its worth, I opened DiskGenius and its now indicating the ESP partition on the SanDisk is damaged. Presumably this is still a problem? I'm still able to boot into Windows as well though, so I don't know what to think.

    1.
    the USB did not show up in the Boot Menu of my Windows 7 machine when inserted into the USB3 port
    The motherboard boot menu has nothing to do with the usb3 drivers inside the wim file.

    Perhaps the port is a bit dicky.


    2. Are you able to boot into windows with only the sandisk attached and no other disks?
