  1. Can't Boot Windows


    Hi everyone,

    Yesterday I went to boot up my computer as always, but instead of booting up, it just attempts to repair the PC and ends up at a screen that says "startup repair couldn't repair your PC". My only options from there are to shut down, or enter advanced options.

    I've since tried about 100 different fixes from various threads/youtube videos but to no avail including:

    • startup repair
    • system restore (no restore points)
    • chkdsk
    • sfc scannow
    • "regback" stuff
    • "fixboot" stuff

    I CAN enter windows via safe boot, but I'm not sure what I can do once I'm in to repair anything.

    I have a USB with windows on it, and I attempted to use it to repair it from there, but that didn't work either. I'd really like to avoid reinstalling windows if it means that I'm going to lose everything.

    FWIW I have a custom build with an MSI motherboard, AMD Radeon r7 370, and an i5.

    Is there anything I'm missing here, or do I just need to do a clean install?

    Sabertooth 990fx won't boot to windows logo, it shuts down

    to boot and enter bios and load windows, any todays PSU (with the correct plugs) will work, AFAIK

    to enter BIOS only low wattage is used.
    Then, during boot, the HDD and a bit later the videocard card start to demand juice, then the other devices and periphericals... so the total demand during boot up is incrementing step by step, that's why a failure halfway could indicate a PSU problem....

    Can't Boot Windows

    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.
