Dual Boot Ubuntu 12.04/Windows8 grub

Question

I installed Ubuntu on 12.04 on my Samsung laptop alongside Windows 8. To install Ubuntu I disabled the bios security and enables CSM OS.

The installation went fine and Ubuntu works great. The problem is that when from the grub menu I select Windows 8 or Windows 8 recovery it doesn't load anything.

If I in the bios I enable the Secure OS option than I don't get the grub menu, but Windows 8 detect some error and after a while loads fine. Disabling again the Secure OS option in the bios, I get the grub menu and Ubuntu works fine.

What can I do to fix this and normally dual boot either Ubuntu or Windows?

Thanks a lot in advance, Luca

Ok the boot-repair option seems to have fixed it. There is only one thing I can't understand, now in the grub menu there are a lot of entry that I can't fully understand like: some .efi and .bkp locations... — lucacerone, Jan 16 '13 at 18:12
