Now THAT'S easy compared with the convoluted BS I had to do (two partitions, fully "by-hand" install, etc) for 11 on my X220. Off to the races I go; now I have to figure out what I have to set in Windows group policy so Bitlocker doesn't throw up every time I boot FreeBSD (this took a bit with my X220 since the boot manager tickled something that Bitlocker interpreted as "someone tampered with the system.")=C2=A0 Maybe this will be a nothingburger too (which would be gr= eat if true.) I'm going to write this one up when I've got it all solid and post it on my blog; hopefully it will help others.
