I was given 4 servers from my company recently. All dell poweredge servers. I am trying to set up my r620...
Firstly I did not want to use RAID at all so I flashed the RAID controller. I flashed it using this guide: https://fohdeesha.com/docs/perc.html and it went fine.
Something I noticed though is that, raid has to be enabled in the BIOS still, even tho we flashed the controller to allow IT mode. If I disable RAID from the BIOS, my live installer doesn't see any of my HDD's. So I left it enabled, but I don't have any RAID configs setup (cleared them from the menu from pressing ctrl+R during boot)
So I try to install my OS (booting from usb) and i remove all the drives from the bays except one.
The OS seems to install perfectly fine. I get zero issues. The imagine below is what happens when I try to boot after installing the OS. I have tried VOID Linux and Debian. Both do the same thing. I am booting in UEFI mode. Please help, any support is appreciated.
I tried 3 different hard drives....

Your flash did not work correctly if you are still able to see anything related to RAID options when interacting with the card. Flashing it into HBA mode takes all of that away and requires a bootloader to be installed in order for a connected drive to be bootable.
