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

  • Then most probably you have accidentally deleted Windows 8 while installing Ubuntu. You might want to try 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 N Jan 12 '13 at 3:53
  • if you look at my boot sequence here: 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 3:56

    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 5:55

    @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 N Jan 12 '13 at 7:50
