attempting to install macos ventura on my vostro 5490 (i5 10210u and nvidia mx250). am pretty sure I did most of the steps right (installing the required kexts, downloading the correct stuff, etc, etc.). but when I attempt to boot via the usb in the boot manager, get a flash of a black screen with some text(too fast to see) and then immediately a loud kinda scary beep noise, then it cues to a supportassist system scan. am aware that because it is an nvidia gpu that it needs to be disabled, but as far as im concerned, i followed the neccesary steps in order to make it work, but am just not sure why it beeps and reacts the way it does. Any ways to fix it? I can also provide the necessary files to diagnose.
