Dual boot are working fine till yesterday... until today, when i start my computer and start windows 8.1 from grub menu, windows 8.1 stuck with grub screen, no further progress.

after boot repair, again it works fine, but in next boot it shows same problem...


  • Run sudo update-grub and try again. – s3lph Apr 14 '15 at 8:35

I have a common problem, except my computer just refuses to boot into Ubuntu.

Disable Windows fast startup, then boot into windows using the live cd. Run the command bootrec/fixmbr and you should be good to go.

Dual boot windows 8.1 stuck


As far as I can see your problem is just the crappy hibernation win 8 does. BTW this feature has many more disadvantages. So you should disable it. To avoid such problems, I would suggest that you install both OS in uefi mode as far as you not already have done. Then you will have no MBR anymore and so you will avoid a lot of dual boot problems.

  • Is it win 8.1 or 8.1 pro? – wstein Apr 14 '15 at 22:11
  • Ok I read the output a second time and mentioned some strange things with your Installation. Did you move some partitions with a tool? It also could be that windows does not detect that an existing image is corrupted and so it tries to load instead of deleting. – wstein Apr 14 '15 at 22:19
