Question Please tell me how to configure raid, maybe I'm doing something wrong. Raid 1 configured in the BIOS LSI sas2 controller. But in boot menu the device does not appear. During boot there is no possibility to press ctrl+a (e or H) to set up a raid. Answer If you need the option rom show during boot, go to BIOS -> Advanced -> PCIe/PCI/PnP Configuration >> Launch Storage OpROM Policy >> change the policy from [UEFI only] to [Legacy only].
