Hi all sages in the forum,

My system:
Ryzen 5 2600
MSI B350 PC-Mate
RAM DDR4 32 GB
AMD Radeon RX 5600XT
Monterey 12.7.6
iMac 19,2

I've been trying to install Ventura (want to update to Sonoma, eventually) by following several guides, but with no success. I tried both a USB and even internal SSD separately as a bootable installation disk, and they showed up in the boot picker; however, it's stuck at Apple logo without a progress bar. I left it for 2 nights, but no change, so I guess it's really stuck there, and so am I.

It would be great if you could help me... I attached my EFI. Thank you in advance.
