• Question

  • I was resetting my windows tablet (I have BUSH Eluma B2 32 GB)  and the power got cut off. Was looking for help because it would not continue or restart the installation. With all the help I got online I got stuck in an infinite install loop at 64%. Everywhere I read they recommend to do a clean install of the system from USB. Got My Microsoft Windows Create Tool... Got my Windows bootable USB, now I get this error UNMOUNTABLE BOOT VOLUME when I try to boot from the USB stick. Any advice?

    I appriciate any help.

    Thank you

    2) Which icons, rotating dots, messages, errors, etc.

    3) When you attach a bootable windows 10 iso which keyboard key did you click to choose the boot device?

    4) How many USB ports are there and are they USB 2 and 3?

    5) What happens when you try different USB ports?

    6) Are you able to boot to another device for example:

    a) memtest86+ drive

    b) bootable Ubunto drive

    7) what is the version and build of the operating system on the computer?

  • Hi

    1) Windows logo, rotating circle, then goes black, shows screen saying Installing Windows, 64% and then reboots, and the same again... and again....

    2) as above

    3) I press ESC + F1 to get to bios, then to boot manager and I choose the USB drive. When choosing the file from the hard drive it keeps on doing things like in 1)

    4) as it is a tablet theres no USB ports. I have one micro USB. I use OTG cable and USB hub with 4 USB 2.0 ports.

    5) No change no matter what I do. I tried even different USB sticks but nothing

    7) Windows 10 32bit and I use the same on my USB Stick

     I haven't tried other operating systems, but will try with Ubuntu. 

    To explain to you exactly how I got to this stage:

    WAs Resetting the system, during which the tablet's battery died. Got this error and was looking for a fix for it. Found this

    Didn't read sadly the comments and did what is recommended... been in a shit since.
