This question already has an answer here:
When I try to use the Ubuntu OS, it doesn't start and I instead get an error saying something to the effect of this:
Windows failed to start. A recent hardware or software might be the cause. File:\ubu\winboot\wubildr.mbr Status: 0xc000007b
The application or operating system couldn't be loaded because of the required file.
I'm using Windows 8 and I installed ubuntu into an empty drive on my laptop.
