This question already has an answer here:
I have (very) recently purchased a new Lenovo Ideapad U510 with a 24 gb SSD, and was quite disappointed with Windows 8. So I am considering replacing it with Ubuntu 12.10. I have some experience in the past with Ubuntu and Mint, and it has always been simple to install or make partitions - but I've been hearing things about the secure boot feature preventing this. At least without taking extra steps. What exactly do I need to do? I've also been hearing about Samsung laptops being bricked because of installing other OSes. Is that the case with Lenovos too? I just want to make sure, as I don't want to risk ruining my laptop's hardware. Thanks.
