Hi,

I tried to do a dualboot on my new dell laptop XPS 15 7590 (intel i9 processor). I already changed the SATA settings to AHCI. I disabled secure boot, partitioned my disk and I have a bootable disk with Rufus. But in order to recognize my disk I needed to check "Enable Legacy Option ROMs" in my bios setup (Settings -> General -> Advanced Boot Options). Unfortunately this option is not there. Only the option "Enable UEFI Network Stack" is available.

 

Can someone help me how I should proceed with this problem?

Thanks in advance!
