I would be surprised if the BIOS is the problem other than the difficulty in changing from a UEFI to a LEGACY boot. The BIOS must have certain standard capabilities to be approved for Wiondows and most graphics systems are well known.
Personally have not bothered much with Linux recently other than Kali for network diagnosis but have played with Fedora and Ubuntu in the past, mostly booting from USB drives & using Rufus.
What are the problems being encountered and with what hardware ? May look into it but all of my hardware is pre-Spin/Swift.
