    Exclamation BT5R2 Gnome X64 USB boot cannnot execute update-grub

    Hello there,

    I downloaded BT5R2 GNOME x64 and tried loading it from my 4GB ScanDisk USB disk. But every time I load startx command, CPU dies resulting in BlackScreen and flashing CAPSLk button.

    I checked for MD5sum and nothing wrong with it.

    I created a live USB using UnetBootin-Windows-575. I can get upto command-line interface and then the "startX" command results in the blackscreen problem.

    I searched the Internet and other threads in this forum but none of them seems to help me.

    I can access GRUB
    Code:
    vim /etc/default/grub
    and then I changed

    Code:
    text splash vga=791
    to

    Code:
    text splash i915.modeset=1 vga=791
    I successfully wrote the changes to grub.

    However, I cannot update grub. When I execute "update-grub" command, it displays error message saying:

    "/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?)"

    I guess as I am booting from my USB it is already mounted. Also, I tried mounting all the devices but that didn't work. How do I solve this?

    System Configuration:

    Video: Intel HD Graphics
    Processor: Intel(R) Core(TM) i3 CPU M330 @ 2.13GHz 2.13 GHz
    RAM: 4GB

    Fine, but as you seek for help, also some other members in the forum are in the same situation as you were, and vlayher is one of them. He is asking you for help.

    Please, post your solution and give away something to those who are in need.

    Luck...
