I've installed Ubuntu (~EFI mode) in a ASUS Zenbook UX32VD, which has Windows 8 pre-installed. It had Security Boot disabled. I installed grub in the same partition I put the root directory (sda7 in my case).

After installation Ubuntu loaded and worked, great.

But there were 2 other partitions in grub that didn't run:

Windows Recovery Enviroment (loaer) (on /dev/sda2)

Windows 8 (loader) (on /dev/sda4)

Whenever I try to load any of the above i got:

error: can't find command <<drivemap>>.

error: invalid EFI file path.

I found in Internet multiple people having similar issues: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1024383

I tried using Boot-repair (recommended repair) utility from Ubuntu, and I've got 2 new entries in grub called:

Windows UEFI bootmgfw.efi

Windows Boot UEFI Loader

They load Windows 8, but the recovery partition is missing. I've tried using Boot-repair more times with different parameters which could make the bootmgfw.efi fail but none added a recovery partition entry:

I'd like to know how can I add an entry to grub that loads the recovery one. Any help to make my recovery partition to load would be greatly appreciated.
