First of all, I had this configuration working, but some recent updates to Windows broke it.
When the laptop starts, it boots the Windows Boot Manager (I think, it doesnt exactly say). Which "lets me choose" between Windows 8.1 and Ubuntu (actually XUbuntu but it's the same).
If I select Ubuntu, it gives an error screen saying:
"Windows could not be started. (...)
File: \NST\NeoGrub.mbr
State: 0xc000007b
Information: could not load application or operative system due to a missing or corrupted file."
If I press Esc and then F9 (Boot Device Options) which shows:
"OS boot Manager
ubuntu (...)
Ubuntu (...)
Boot From EFI File"
I dont know why I have two options for Ubuntu (actually I'll make a post later maybe since I've seen some weird stuff in gparted) but if I pick any of those, Grub 2.02 starts and I can choose XUbuntu with no problem.
I ran boot-repair with default configurations, here's the report: http://paste.ubuntu.com/12324210/
Nothing changed, and actually, now, on Grub, the list of options is much larger, showing many options which end in ".efi"
The report says at the end:
Boot successfully repaired.
You can now reboot your computer.
The boot files of [The OS now in use - Ubuntu 14.04.2 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of . (https://help.ubuntu.com/community/BootPartition)
If your computer reboots directly into Windows, try to change the boot order in your BIOS.
If your BIOS does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, [B]then type the following command in an admin command prompt: bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi
I checked the boot other on the BIOS, but either with OS Boot Manager and HardDrive/USB/etc. its the same as I mentioned before.
I tried running that command on the Windows console, but nothing changes.
I went to do the gparted and the boot partition thing, but when I opened gparted I encountered this:

(maybe thats why I have two Ubuntu options in the Boot Device Options menu) and didn't really wanted to screw anything up.
Basically, what can I do to fix this boot issue?
