I thought this iMac had fusion drive issue or maybe was the original problem but I think there is issue with the bios. It will load mojave and big sur but has issues loaading monterey and ventura. I can boot them if drive is preloaded with ventura but it won't update and when trying to install monterey or ventura it fails loading the update. I have it plugged into ethernet and connected to wifi.
Can you do a clean ME on my bin file on google drive link below and/or provide known good bios? It was too big to attach.
