    Dual Boot Issues


    I'm in a Networking Class and my Teacher had the wonderful idea of dual booting Ubuntu and Windows 10 Pro. Things were okay until last night when I booted my machine I'm stuck in the grub rescue. Now at some point I didn't actually uninstall Linux but deleted the partition. I tried to use my Win10 rescue disk but it won't work. Is there a way out of this to get back into my Windows without having to reformat/reinstall?

    Thanks

    If Startup Repair (Windows bootable install medium) doesn't work, then try Macrium Reflect's Fix Boot utility (on their boot disk - also on Kyhi's very useful boot disk - from the top of the Software and Apps section here).

    However I should wait for guidance from someone familiar with dual booting Linux.

    That MR Rescue or Kyhi's Rescue is the go-to fix for these things, but I'd be curious to see what this looks like. If all he did was delete the Ubuntu partition, the config may still show in MSCONFIG, and just needs to be deleted and re-boot. It may fix itself. Just a thought.....

    Example only:

    The one for Kyhi's Rescue is: Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums

    Macrium is: Backup and Restore with Macrium Reflect Windows 10 Backup Restore Tutorials

    You'll have to get on a different machine and get the software and install the rescue's to a thumb drive. Than come back and boot from the thumb on your busted one.

    It may be easier to use Kyhi's disk, 'cos to get M Reflect's boot medium, you first have to install Macrium. On the other hand, Macrium will then do the work for you creating a bootable USB drive.

    Kyhi's disk is a very useful tool to have, with a range of software as you can see from the screenshot and list.

    Note how to create a bootable drive from an iso file:

    - you can burn a DVD (easy)

    Creating a bootable USB drive.

    with thanks to @NavyLCDR
    To reliably make a bootable USB flash drive from an ISO file, do this:

    Plug the drive into a USB port of a functioning Windows PC.

    Open a command prompt.
    Run diskpart.

    Once diskpart is running, enter the following commands in sequence:

    list disk
    select disk #
    - replace # with the actual disk number of the USB flash drive
    clean
    - this will erase the selected drive, make sure it is the USB flash drive!
    create part pri
    format fs=fat32 quick
    active
    exit
    exit

    Then mount your ISO file.
    (By default you can simply right click the iso file, and click Mount. However, Mount will not be available if iso files have been associated with a different program).

    Copy all the files and folders from the mounted ISO file to the USB flash drive.

    (If stuck you can open the iso with 7-zip, a free program).

    Running Macrium Fix Boot
    Boot your PC from the boot drive, and you should see a desktop display. Start Macrium Reflect. Under the restore menu, select the utility

    Is this your own PC ?

    Why are you using your PC ?

    You should be using the one`s at the school and the teacher should be helping you with this problem.

    According to his specs, it's his machine, custom built. Desktop. He doesn't say so directly, but I suspect the Networking Class is Online.

    Unless he is using a laptop not mentioned or listed. Home or school.
