I upgraded my trusty ThinkPad L520 to a shiny new ThinkPad T440s. Unfortunantly, but not unexpectedly,I tried to follow online tutorials for dual booting and ended up with a lovely black screen every time I tried toboot from the USB Live image I’d created.
To re-iterate, disabled Fast Boot in Windows, and Secure Boot in BIOS/UEFI. I also enabled legacy boot mode, but itdidn’t seem to make a difference. Got all that? These are the recommended settings for dual booting / installing linuxon a UEFI/Secure Boot enabled box.
I went to bed unhappy, but in the morning had the crazy idea to enable Secure Boot, just to see if it would work.It did! So, it looks like new Ubuntu versions are supported in Secure Boot. Good enough for me.
I was then able to install Ubuntu 14.04 LTS on my shiny new T440s… not without other issues though…
Like I did with my ThinkPad L520, I’ve created a page to document the different issues I’ve experienced.My intention is to keep it updated with issues and solutions over the life of this laptop – similarto what I did with my L520.
