Easybcd

I could access windows files from the drive in Ubuntu. Then I searched for the location where easybcd was installed and and found backups of the bcd file. (gave me little hope that something could be possibly done)

I haven't used the software in a while, but there should be a Linux option in the add entry tab. The software is supposed to be UEFI ready. I had used easybcd for years, but only on legacy bios machines.
