Hi There, I've scoured everywhere & I'm still all very confused. Since I'm a total noob, I don't really want to touch too many files...

I have an Acer M5 with Windows 8 preinstalled. I installed Ubuntu 12.10 in secure boot, but Grub does not recognize my Windows 8. I tried boot-repair, to no avail.

Here are my specs: http://paste.ubuntu.com/1522276/

Please help?

Launch a terminal by pressing Ctrl+Alt+T and type sudo os-prober and check if it detects your windows 8. IF it detects windows 8 then do sudo update-grub.

To install os prober do sudo apt-get install os-prober

  • hi, i launched my terminal & installed & ran os-prober, it didn't show anything, or load anything... – ise Jan 12 '13 at 03:52
  • Then most probably you have accidentally deleted Windows 8 while installing Ubuntu. You might want to try http://www.supergrubdisk.org/ to check if it detects windows 8. You have to burn it to usb pen drive or CD. Use dd command in terminal dd if=/path/to/isofile/supergrubdisk.iso of=/dev/Xda where X is the name of your pen drive. Use fdisk -l to know name of your pen drive. – Abhijit Navale Jan 12 '13 at 03:53
  • if you look at my boot sequence here: http://paste.ubuntu.com/1522276/ - i believe my Windows 8 lives in /sda4 - so I don't believe i deleted it, since i created a partition specifically for Ubuntu before installing, i just don't think my Grub is reading my Windows... – ise Jan 12 '13 at 03:56

  • Hi Abhijit, thanks for the link but I don't think this is helpig me, since I am not loading Windows 7 or 12.04 - in fact, my Windows 7 machine is successfully dual booted... may you be able to clarify maybe what I should be looking at? the os-prober part? boot-repair printed out my boot sequence here http://paste.ubuntu.com/1522276/ - i believe my next step is to configure Grub accordingly to my specs. – ise Jan 12 '13 at 04:05
  • Have you followed that question completely? Though you are not using windows 7 it do not make a 'great' difference. It does make a difference but not significant. You can still follow that post to resolve your windows 8 issue. – Abhijit Navale Jan 12 '13 at 04:12

    I had similar problem with win 7 because I installed UBUNTU in UEFI, but WIN 7 was on legacy. I inserted win 7 OS installation disk, booted from it, selected repair, opend up command prompt and typed "bootrec /fixmbr" and then "bootrec /fixboot". This made win 7 load properly, but GRUB was removed, Then I installed UBUNTU in legacy mode too, then everything went fine – Gaurav Sharma Jan 12 '13 at 05:55

    @GauravSharma You might want to write this as a separate answer with all the detailed steps rather than writing it as just a comment here. – Abhijit Navale Jan 12 '13 at 07:50
