I am having problems installing server 2012 r2. I am trying to set up a lab to learn server 2012 r2 for certifications. I have tried on both my Win7 and Win 8.1 partitions (dual boot system, so no UEFI). I have tried with and without different features enabled in the BIOS. I keep getting error 0xc00000e9 after "loading files" is displayed.

We were having some similar issues at school, but they resolved it and not able to on mine.

Any help would be appreciated.

Did you use the correct OS type for the guest? Use "2012 (64-bit)" for your guest.

Yes, I have. I have attached a screenshot of error. I also made sure that no USB devices were plugged in then restarted computer and VB.
