  1. Windows-10 does not boot after May, 2021 Update


    Have a computer with Windows-10 and Linux installed. Using Grub to boot, Windows was the default. After the update apparently failed neither Windows nor Linux will boot. Booted from GParted but it shows just ntfs partitions + 1 unallocated partition of 135 GB which may have been Linux partition but is now apparently unrecoverable. Booted from Windows-10 DVD but that just enters "grub rescue" command prompt. Thus windows DVD will not boot the computer either.Do I just reformat all the hard drive? I have a lot of data + proprietary expensive programs on the computer.

    :)

  3. Windows 10 USB boot

    Hi there, am not a windows 10 expert. I have a pc in the bedroom on windows 10, I messed up the bootloader trying to fix the xp on that system.

    System wont boot, trying to repair via win 10 usb installer.

    Downloaded the media creation tool to install windows 10 installer on usb stick. Not compatible with a host of usb sticks I have. Tried the usb sticks that others use, but I think they use rufus; as the media creation tool by win 10 does not detect the usb stick.

    So quick question, the win10 machine i am trying to repair the bootloader is a win7 upgraded to win10.
    If i were to use the usb win10 installer to "repair installation" does the version of the iso downloaded via the media creation tool matter?

    There is three options:
    Windows 10
    Windows 10 Home
    Windows 10 N

    Also is there a step by step instead of using rufus as I want to try an alternative method of creating a usb win 10 installer. Preferably with more compatibility.

    System is a asus sabertooth 990 (r2?) with AMD phenom X 6.

    Also is there any other software I can load onto the usb that can repair the bootloader easily?
    That would be the ideal alternative. Thanks

    windows 10 slow boot

    I was having a slow boot issue on my Windows 7 install a little while back. It would take about 30 - 40 extra seconds to boot up for whatever reason.

    I would try following these steps, while this didn't solve my issue, it did increase Read/Write to where it should be.

    Looks to be similar to this: https://www.back2gaming.com/focus-story/ssd-optimization-for-windows-10-windows-8-and-8-1/


    In the end, I had to reinstall my Windows 7 entirely to fix the booting issue. It was taking around 35 seconds to boot, and after the fresh install it takes about 7 seconds to boot.
