Hoiw to disable safebios
I have a xps 13 9350 purchased this year (2025) and would like to disable the dell safebios so that i can use another OS. I am having difficulty finding a step by step how to. I can get into the BIOS, but I don't know the correct sequence. Help appreciated

If you're looking to install an OS that needs legacy mode, you can't -- this system has no legacy support. Like just about all new systems from recent years, it's UEFI only. If whatever OS you want to install needs legacy mode support, you need an older system. It's gone from new systems at this point.

@ejn63 I want to use an OS that runs solely in RAM. It is called TAILs and boots from a USB. Presently, SafeBios prevents it from booting.

Disable secure boot in Setup (F2 at powerup). That should do the job.
