So I think I have a unique situation here. My work computer came with windows 8 preinstalled on an SSD. The SSD was needed elsewhere and I got a new one in the mail. To preserve windows 8, a coworker cloned the operating system to an image file using dd.

Note I have two drives, an 256gb ssd, and a 1tb sata.

I then installed Ubuntu 13.10 to my new SSD and it works splendidly. When it came time to dd the image file onto my sata hard drive, the dd went well as well. Mounting the filesystem from within ubuntu, all of the files etc are there.

This sata is the first connected hard disk (sda1) and windows has the whole partition to itself.

The problem: Grub won't recognize windows 8. It was a factory install which means that I believe it was installed with efi. Ubuntu currently does not boot in UEFI mode. Even by restoring the mbr on sda with the default HD to boot being sdb, overriding it to boot to sda which shouldnt have grub and thereby should just try to boot to the disk nothing happens.

Can someone link me to some relevant resources pertinent to fixing this situation?

Probably you need to reinstall the GRUB. You can use a LiveCD and chrooting and then use my guide here I need my pendrive to boot into Ubuntu, how to correct this and boot from the HDD? –  Braiam Nov 24 '13 at 22:25
Grub has been purged and reinstalled several times using boot repair –  Senjai Nov 24 '13 at 22:29
Boot repair doesn't seems to chrooting Ubuntu, at least I never needed it to fix my GRUB. –  Braiam Nov 24 '13 at 22:40
If Windows is UEFI and Ubuntu BIOS with MBR partitioning you will not be able to dual boot from grub. UEFI and BIOS are not really compatible, so once you start booting one way you cannot switch. But you should be able to go into UEFI/BIOS turn on UEFI mode and boot Windows or turn off UEFI mode and turn on CSM/Legacy and boot Ubuntu in BIOS mode. May be better long term to convert Ubuntu to UEFI. –  oldfred Nov 24 '13 at 22:51
Braiam: when used from an installed session, Boot-Repair reinstalls GRUB without chroot. When used from a live-disk, it uses chroot to reinstall GRUB. Boot-Repair can install GRUB in many situations not covered by your guide (UEFI, RAID, LVM, purge, separate /boot ...). Senjai has a factory install of Win8 so he needs UEFI. –  LovinBuntu Nov 26 '13 at 22:41
