As I don't have access to a usb or CD, I have tried to frugal install ubuntu onto my HDD, using Unetbootin. Once turning on I find the dual boot menu to select the OS, and attempt to boot Ubuntu, with no avail. An error appears saying
Windows failed to start.A recent hardware or software problem might be the case.
It then says File:
ubnldr.mbr status: 0xc00007B.
Does anyone know a solution?
