Re: L520 disk change

Hi Hortus! Welcome to our forums community. Your Thinkpad L520 came along with the HDD SATA and you can refer to the detailed specs here:

In the BIOS, you need to disable the Secure Boot, the boot option should be Legacy only, disable OS Optimization and the CSM should be set to YES. Hope this works for you.
