Monterey on mid 2009 imac (help)

Hi, ive been trying to get open core to work on my mid 2009 imac for about a week and ive had a few issues. At first when installing and doing everything to book using a usb flash drive on the machine it would install and then get stuck at the apple logo with message reading "less than one min remaining" I would let this sit like this for 4-5 hours and at about 4 hrs when i pressed the caps lock key and didnt see a green light, i knew it was frozen. I got around this by opening up a (i think mid) 2015 imac and installing the ssd that was in the 2009 into the 2015, this worked and i was able to install Monterey on it with no issues, however when going to transfer that same ssd to the 2009 imac. it turns on and get stuck with the apple logo, and a bar about 1/3 way finished. im wondering if this could be because i only have 2gb of ram, or something in the settings of open core, if anyone has any idea how i could get this to work, it would be appreciated.
