I understand. I used to use Debian on an old Radeon card in 2009 on my first computer (was 9 yrs old at the time, got a family friend to install Debian Lenny for me). Used it up to Wheezy. Then I got new hardware, Debian wouldn't recognize the WiFi card and I kind of switched to Ubuntu. Then got other new hardware, Linux wouldn't work, shitty AMD APUs... I'm right now installing Ubuntu 16.10 on a new model netbook and it works pretty well, everything was recognized, and I'm typing this on it. It's very smooth and fast, but on an E1-2100 AMD APU it's extremely stuttering and slow and unreliable and crashing. And that's both with FOSS and Closed Source drivers.
Ha Ha it won't boot, because of SecureBoot which cannot be disabled without disabling UEFI which causes a delay of 10 seconds on power up. Stupid computers ugh!
Are you I/O limited perchance? I have a really low end x100e, and even that doesn't stutter. Your E1-2100 should be head and shoulders above it performance wise, hopefully it is less of a space heater too (tho the x100e gets 5hrs despite that)!
