I'm trying to get dual boot on my laptop for Windows 8 (which was pre-installed) and Ubuntu 12.10.
I have gone through quite a lot of struggling already:
1. It seems there was some Ubuntu installation bug related to Windows UEFI boot.
2. After running boot-repair, I still wasn't able to enter Windows, as I had to disable secure boot (and I think I had to go into Windows to get access to BIOS)
This post helped me a lot through the process:
The thing now is: no matter how many times I run boot-repair, it works perfectly as long as I only go into Ubuntu. First time I run Windows, my PC stops showing me the grub menu and I cannot run Ubuntu anymore (until I run boot-repair again from live CD).
This is URL boot-repair generates:
Thanks a lot for your time and your help!
(*1) If possible, I wouldn't like to repeat that ever again
