is it safe to disable Legacy Option Roms and enable Secure boot on XPS 15 9560
XPS 15 9560
I just want to enable secure boot, but I have discovered that a prerequisite to this is disabling the Legacy Options Roms setting. Is this safe to do?

The answer depends on how Windows is currently set up. Most likely it's on a disc partitioned as MBR (master boot record). If it is, you will need to repartition, reformat and reinstall Windows to switch over to GPT (UEFI) mode, which will then allow you to enable secure boot.
Simply disabling the CSM (option ROM) mode will not allow secure boot to work -- you must install Windows in GPT/UEFI mode.

sorry for the late response.
On msinfo32 my BIOS mode is UEFI, and my Disk is in GUID Partition Table under partition style.
sorry for not presenting this info earlier, is this a yes for the question then?
