    Can't boot to command prompt


    Hi, I am trying to boot into the command prompt to reset a password. However, none of the function keys including escape allows me into the BIOS. I am using a wired keyboard and function keys do not have a toggle on/off option. I have restarted with the SHIFT key and it won't allow me into command prompt as well as safe mode, UEFI or startup repair etc. I have noticed from 'system information' 'secure boot' is set to ON.

    Thanks

    :)

    Installation media boots to command prompt

    I've just booted from known working install media to see exactly what it does when booting. The sequence of events is...

    1. Windows logo on a black screen
    2. circling dots appear beneath the logo
    3. light blue 'Please wait' screen with circling dots
    4. a command prompt window (very briefly)
    5. the initial Setup page appears

    Do you see steps 1-3? If so, it appears you have stopped at step 4, suggesting that something on the disc cannot be read.

    Does the disc boot properly in another machine? If so, try cleaning the laptop's drive lens then try booting from the disc again.

    If not, make new install media with Microsoft's Media Creation Tool, either as a bootable USB, on an ISO that you can burn to another disc. At Step 8 in Option One of this tutorial you can choose between making a USB or an ISO.

    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?

    Can't boot to command prompt

    How does Windows boot to advanced recovery option e.g. command prompt?


    - that gives me a 454 'Unexpected error' This tells me that the BCD is partially corrupted.

    The commands: shutdown.exe /r /o /f /t 00
    or: %SystemRoot%\System32\Cmd.exe /c reagentc /boottore&shutdown /r /f /t 00
    should boot into Recovery if everything is configured correctly.
    FYI, If Windows is configured correctly:
    1. If Reagentc is disabled, you still can get into Recovery but with limited options.
    2. If Reagentc is enabled, you'll get all options.
    3. If you boot Windows using Recovery USB stick, You'll get into Recovery with couple of options missing.

    Here's my suggestion if you want to try:
    OPTION 1: Will save the trouble of re-install Windows.

    1. Download the image of my first 3 partitions (450MB Recovery, 100 MB EFI partition, and 16MB unformatted primary)
      EFI_Boot-00-00.7z - Google Drive
    2. Run Macrium and restore the image from step 1, overwriting your existing 1st three partitions, leaving C alone.
    3. Delete the 490MB Recovery partition.
    4. From Macrium, run fix boot problems.
    5. Reboot. Open Admin command prompt then run Reagentc /info to make sure that it is enabled. If not, enable it.
      if failed to enable, reboot and try again.
    OPTION 2: Assuming you've already had Windows backup with Macrium.

    1. Wipe out the first 5 parttiions. (450MB, 100MB, 16MB, C Drive, 480MB)
    2. Fresh install Windows 10
    3. Restore C drive from backup image, run fix boot problems
    4. repeat step 5 from OPTION 1 above.
