Re: UEFI install

[Corey Blair <cblair2k2@yahoo.com>]

I downloaded debian-7.4.0-amd64-DVD-1.iso and then used unetbootin to 
make a bootable USB flash drive from it.  I changed UEFI boot to legacy 
mode and booted off the UEFI USB.  The installer runs fine, but I have 
trouble loading the components from "cd-rom", so I execute a shell and 
mount /dev/sdb /cdrom, which used to work but now it's failing with 
"invalid argument".

When it was working I went through, partitioned some space for Debian, 
got all the way to GRUB and I get something about grub failed to install 
to /target/.  I'd try to run the install again and get the exact message 
but now I am having difficulties with even loading the components off USB.
