How to fix boot issues on Great Wall GW3300 256GB?
Every time I launch the game, I'm staring at a black screen for 20 seconds. It's absolutely infuriating and kills all the hype of getting into the game. The UEFI boot on the Great Wall GW3300 256GB was struggling with the large partition table, causing the SSD initialization to hang between 110-160ms. I tried disabling all startup apps in Windows, but that only shaved off 3 seconds—a total joke. I went into the BIOS, completely disabled CSM compatibility mode, forced the boot priority to 'Windows Boot Manager', and enabled Fast Boot. Using a boot timer, the time from power-on to the loading screen dropped from 40 seconds to 15 seconds. I did run into a problem where my backup drive disappeared after disabling CSM, but converting it to GPT fixed it. Motherboard idle is 40-45℃ and the SSD is 32-38℃. I used a BIOS export tool to save these boot parameters; config backed up.
