ubuntu - Windows Rebooting to Blackscreen after removing WUBI

    I wanted to install Ubuntu and Win 8.1 in DualBoot. I used Wubi to install Ubuntu. After rebooting and not accessing Ubuntu I removed Wubi.
    Now my Acer Aspire V2-772G does not restart. Using bootrec.exe /fixmbr and /fixboot and /rebuidbcd do not fix the problem.
    It starts the process to shutdown but it stays in a blackscreen and nothing happens anymore... so it ends up in a blackscreen of nothingness.
    Thank you so far.
    Regards j0chn
    Edit:
    It seems that the command on restart is active (e.g. I wanted to reboot into advanced boot options for debug mode, so I restartet the Laptop. But it did not shutdown so I pressed the power button and after booting it again the advanced booting options appeared), so my conclusion is, that it just don't shutdown properly.

    windows - My computer reboots when I tell it to shutdown
  • Stacey Richards

    There are about 40 computers at work with this problem. They all have an ASUS P5KPL/1600 motherboard. They are all running SUSE Linux 11.1.

    When I tell the computer to shutdown either through the UI or by issuing

    shutdown -h now

    in a root terminal, the computer wull shutdown for about 1 second and then powers back on again.

    I have disabled all the wake on events in the BIOS just to make sure it's not an external event that's causing the computer to restart.

    I've tried booting with an Ubuntu live CD to see whether the problem was with SUSE specifically. Shutting down from Ubuntu also doesn't work; the computer just restarts.

    The IT guys at work tell me that the same machines (machines with the same motherboard) power down fine when Windows XP is installed.

    If I boot the computer, enter the BIOS and save without making any changes, on the next reboot the computer will shutdown and stay off when told to do so from either SUSE or Ubuntu. After that, it goes back to rebooting every time it's suppose to shutdown.

    Any ideas as to why I can't power them down with Linux?

    I asked the IT guys to try removing the PCI/PCIE cards that were installed to see if they were affecting the shutdown process.

    Sure enough, removing a Moschip Semiconductor serial/parallel port PCIE device resolved the problem.

    I have had cases where even though the BIOS is set to not wake for anything, it still does (especially hard wired NIC - PSU based machines).

    Try unplugging your Ethernet Cable, and then shutdown. This will show if it is any sort of "magic packet" that is being sent, even without your knowledge.

    It's perfectly possible that there's a hardware or firmware flaw. Flashing the BIOS might help. If not, you could actually install Windows (or borrow someone's hard disk running Windows, since these computers have the same hardware) and see if Windows can shut it down.
