ThinkPad W530: Windows 8.1 & Ubuntu 14.04 dual boot?

[jonashendrickx]

I never used Linux again when Windows 8 came out. Secure boot seemed like the end of dual booting. Now I was hoping to give it a try again.

I have a Samsung 840 Evo, so I have a little bit of spare room (100GB) to dedicate to Ubuntu.

Does anyone know the best way to set up a dual boot? And probably the easiest? I reinstall Windows quite often, every three months.

I have was thinking of buying a 128GB mSATA drive to dedicate to Ubuntu, so I can switch operating systems using the F12 boot menu. Which is probably the easiest way.

I am very good working with Windows. Linux in general perhaps not so much. I can do basic things like setting up a DNS, DHCP, SSH access without prompting a password and so on, using vim, wrote a few tutorials in the past.

But reading all the different dual boot guides available, gives me a bit the creeps.

Here is the log from boot-repair. I ran into a issue where I would be stuck at 'loading RAM disk', then my fan would start to spin very fast. Or I would have just a blank screen.
It was working fine before running boot-repair however.

The only error I see at first sight is on line 9400 that the wrong GRUB version is detected.
