I wanted to try playing Valorant but realized I needed to turn on secure boot. My NVMe is set up as a GBT partition. When I activated secure boot with the custom platform keys, my PC wouldn’t start and kept beeping five times. I attempted to reset the CMOS, removed the batteries, and connected the pins using a screwdriver. I understood I should have done more research before enabling secure boot—please help me, I really need it. My motherboard is H370M, CPU is i5 8400, RAM is 4x4, crucial ballistic sport HDD: NVMe SSD, two HDDs (they’re still MBR and aren’t boot drives, so it probably doesn’t matter).

I attempted to turn on secure boot by disabling CSM, but it asked for a platform key. I updated the custom key and restarted my PC, which finally allowed secure boot. However, after another restart, the system wouldn’t boot properly.
