You may not install to this volume because the computer is missing a firmware partition

Not sure why im getting this when selecting the hd to install. Ive tried both apple format with partition man and os extended jornal with partition map get the same result.

Side note. I had Cat installed and working on the drive. It is a SATA drive. Is this maybe the problem? What files from me do you need to help diagnose.

Thanks in advance.

Sounds like you are only formatting a partition. You need to format the full drive.

OK i figured out out. Well i used to never have above 4g decoding in my bios. But with im not sure what update it got put there. I turned that on in bios removed the boot arg for pcie 2000 thing. Also saw that my serial port got turned back on so fixed that. And also had to fix from other to ueif on os boot. After i did all that i was able to install big sur. Not finished setting it up. Ill work on that later since im tired. But not sure which one fixed the issue i was having.
Thanks for the help you did give.
