    Issues with dual boot gone awry


    Howdy

    I had a dual-boot situation where I had windows 10 on one hard drive and ubuntu linux on another. I think the grub resided on the windows HD. The windows HD was the master and would boot first. I would then choose which OS I wanted to load. I believe the grub was placed there by ubuntu when I installed it on the 2nd hard drive.

    Fast forward to today. I went to install a different version of linux on my hard drive. When I did so, the grub on the windows HD failed to load correctly. Now when I try to load the windows HD all I get is:

    error: no such device: xxxxx-xxx-xxx
    Entering rescue mode...
    grub rescue>
    That's all I get and I have no idea how to get past this screen or the grub rescue prompt so that windows will load. Unfortunately I don't have any sort of windows cd or other recovery tool. Any help is appreciated.

    If you have working Windows OS computer use Windows 10 Media Creation Tool to create a bootable Windows 10 media.
    You can boot your computer into Windows 10.

    Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

    Please type below commands into Command Prompt and press Enter key.

    Following commands will repair Master Boot Record (MBR), Boot Sector and BCD Store.


    Code:
    Bootrec /FixMbr
    
    Bootrec  /FixBoot
    
    Bootrec  /RebuildBcd

    Once you get it working, virtualize Ubuntu. Much easier and won't affect your main OS.

    I've always had trouble with virtualizing because I can never figure out how to install an OS with a usb drive instead of a cd/dvd.

    You install using the .iso file. It's quicker and in some ways, easier than installing on a physical system.
