20.04 boot to megaraid – Ask Ubuntu

I have a gigabyte mb with a lsi megaraid pci card with 8 1tb drives in a raid 10. My pc started giving off the hd failed noise.
Before today I had windows 10 and Ubuntu 18 when this happened. I could do a ctrl+? In order to install a virtual cd and change bios settings to boot to it in order to get to the raid config.
Since installing 20.04, it is no longer an option. Everytime I boot my pc it’s endless siren with no way to stop it, repair the raid, swap the bad drive with a new one………
