Hi everyone, recently got a 2nd hand 27"-2009 iMac, honestly pretty awesome and still fast, but the GPU failed pretty fast and the baking stopped being an option. Happy ending 
: the machine is up and running with an unsupported GPU, the Nvidia Quadro 1000m with 2G RAM. I mostly use Windows 10, so I have no worries or hopes regarding MacOS. Yes I lost brightness control, but long story short, I managed to get it back with a hardware modification, if you are curious check here.
At present time this is not a problem, because I made a modification moving the optical drive (now an HDD caddy) to the back of the iMac (the stand basically) so I can move data, mount the disk, whatever on my other computers. On the main 1T hard drive I have Ventoy (a multi boot solution) along with multiple Iso files and VHD (virtual machine hard drives), I can basically boot whatever I want. But yes, no USB boot options.
Questions:
I'm not as knowledgeable about macs as I'm on PC, and I'm not really familiar with OpenCore. I've read about it, and it seems confusing to me, for all that matters, I understand (via readings) that it has to be installed from within MacOS, or via USB, but USB booting is no longer an option for me. I might try converting whatever USB boot option into an ISO and boot from Ventoy, but I need to first understand my options and risks. Found mentions that OpenCore might mess up my Mac, I don't know.
As far as I can see, OpenCore gets installed on the iMac (firmware or something like that) and not on a hard drive, is that so? I understand this brings back the boot menu along with displaying it (due to lack of supported GPU), would that work on a fully unsupported GPU? how do I know if it works with the Nvidia Quadro 1000m? (as I understand it takes some injection of drivers, I don't know). I did search, and there are no mac drivers for this GPU, but it works pretty well on Windows and Linux.
Any advice anyone would like to share?
* I'm also trying to remove the boot sound, but dosdude1 says 2009 imacs are too tricky and not entirely safe to dump the firmware or flash it, and a chip programmer is needed for these models. Searched for ways to do this in Linux but found people saying it's tricky (risky) and could ruin my firmware. Found info saying how to do this on MacOS, but I don't think I can boot it anymore.
