I just got Ubuntu 12.04 (also have it on my Chromebook), and I installed it on my seperate hard drive. Whenever I try to boot my computer up, I get Windows Boot Manager, as expected. But then there's a problem. When I click "Ubuntu", this error message pops up:

File: \ubuntu\winboot\wubildr.mbr

Status: 0xc000007b

I have seen other questions like this, but this is on my separate hard drive. It might be that I have a UEFI motherboard. I checked for a "legacy boot" option, but can't find it.

Thanks in advance!

Is it a WUBI install? – DaboRoss Jun 7 '13 at 23:57
Yes, I'm trying to figure out how to remove the WUBI to make it GRUB. – tjhorner Jun 8 '13 at 3:56
I don't think WUBI will work correctly on an external drive. Windows is complaining about WUBI not being found where it was originally installed, this is probably due to the fact that it is on a separate hard drive. – DaboRoss Jun 8 '13 at 4:25
Check out – DaboRoss Jun 8 '13 at 4:26
Thanks, I'll go check it out and see if it works. Edit: Well, that doesn't really work for me because Ubuntu won't even start up... and I don't want to override my existing Windows installation. – tjhorner Jun 8 '13 at 4:40


the error message you got means you tried to install Ubuntu inside Windows (via the Wubi installer). The problem is that Wubi is not compatible with GPT (preinstalled Windows8 and some Win7 are on GPT disks).


Install Ubuntu the standard way, on its own partitions, see

Well, Wubi isn't compatible with my mainboard. I tried the graphical install from the LiveUSB... with UEFI, which was stupid because I couldn't see the GUI... then I used Legacy boot. It works! Thanks for all of your help guys :)
