I have a problem with my shutdown and reboot on Windows 8.1.
I installed Ubuntu with Wubi (want Dual boot). But unfortunately my Acer Aspire V3-772G does not shutdown / reboot. It starts the process to shutdown but it stays in a blackscreen and nothing happens anymore...
Maybe you can help me.
Thank you very much!
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.

  • I thought stackoverflow was more of a programming question / answer place. One of the other sites on StackExchange might be better suited for your question? Maybe http://superuser.com/ – Gavin Dec 30 '13 at 20:51
  • Hey, thanks for the link. I only looked for Microsoft and Windows sites. So I missed superuser... Thank you! – j0chn Dec 30 '13 at 21:05

Windows 8 has a protected BIOS thing. You have to go into Windows settings and disable the BIOS protection feature and then reboot. I had this problem when installing Ubuntu on an Acer laptop myself.

    In BIOS itself I set a supervisor password and disable secure boot (after the problem appeared.) When I access the UEFI Settings (by holding shift and restarting Windows) I will be directed into bios. – j0chn Dec 30 '13 at 21:28

I had this with a dell 3020 after installing ubuntu using wubi. I think the ubuntu version at the time was 12 LTR. Upgrading to ubuntu 14.04 it cleared the problem. I think its possibly down to bug in a power management driver somewhere.
