“When I tried to install the operating system of my choice, I found it wasn’t possible because the computer had a Secure Boot loading option. This feature requires that any operating system installed on the computer must be authorized through digital signatures issued by Microsoft. I tried to disable Secure Boot since it prevented the installation of the operating system I wanted, but my attempts to deactivate the feature were unsuccessful.”
See In Defense of Free Software: My Case Against Lenovo in MexicoRemember the fears rampant when “Secure Boot” appeared? M$ could prevent installation of GNU/Linux? Well, we were told that the user/owner of the PC could disable it and normal installation would ensue. Well, there’s a case in Mexico where a model from Lenovo wherein “Secure Boot” could not be disabled….
A court of law ruled that Lenovo had broken the law by not informing the buyer of this problem. Perhaps Lenovo was not even aware of the problem because they offered to disable it and show the consumer but Lenovo could not do it. So far Lenovo has not provided any remedy.
