    After a Windows 10 update my Dell X8900 desktop would not boot up. I got the error message no OS available.

    I went to the command prompt and it looks like my C: was changed to an X: drive and it has all my files but is not bootable.

    if I can get my Windows 10 divd to install could I copy my files from the command prompt to the new Windows 10 directory?

    :)

    BSOD - drive C changed to drive X

    After the restart following the 11/18/2017 Win10 64bit Pro update, I have the BSOD with stop code 0xc000021a. I am able to access the command prompt....Troubleshooting revealed that what was drive C is now drive X. At the command line, I can access a drive
    C is but it is empty. A directory listing of drive X appears to show everything that should be on drive C. I suspect the update possibly failed at some point causing this problem. How can I fix it?

    Moved from: Windows / Windows 10 / Windows update, recovery, & backup

    Dual Booting 2 x Windows 10 OS Drives (Existing Installs)


    It is uneccessary to do all of the above.
    1. Boot up Windows 10
    2. Open Disk Management and take a note of the drive letter of the other Windows 10
    3. Open Admin Command Prompt and type: bcdboot X:\Windows where X is the drive letter noted in step 2
    4. Reboot, you should have a dual boot menu.

    command prompt will not open in safe mode with command prompt

    Would I just follow the same steps within safe mode after hooking up to the other system?
