Hello all,
I'm trying to install Ubuntu 16.04 alongside Windows 10 from a USB drive. The installation always crashes when trying to install the bootloader, regardless of what options I choose. The device is free of errors and the Ubuntu image md5 checks out.
I was advised to come here with this report from Boot Repair, which I used from Ubuntu Live: http://paste2.org/bgHj1czO
If it's important, I don't remember if I installed windows in UEFI mode. I can't imagine I'd ever do otherwise, though, and I'm not sure how to find out once it's been done.
Thank you in advance!
