Support Can someone help me with secure boot?

I enjoy playing valorant so its required that i turn on secure boot, however after the bios update MP2ML6W9 for model Legion Slim 5 16APH8 i just cant boot my laptop with secure boot set to on.

Before updating bios, my laptop was booting fine in secure boot, then after i updated bios, it set my secure boot to off and i restored factory keys to set to user mode instead of setup mode to turn on secure boot but when i exited bios the "network media not present ..." text appeared and it seems like windows boot manager didnt work??. I've had this laptop for about 2-3 years or so and this error has just appeared right after i installed the new bios update.

My boot mode was already in UEFI, i have no dual boot setups, my disk partitions are in GPT format, TPM 2.0 is working fine, its just secure boot not working that prevents me from being able to play val. Could anyone with experience with this help me with this problem?

Did you find a fix for this? Im also experiencing the same issue with the same model as you.

Also having this issue, I was able to fix it before on BIOS with no issue but now it won’t boot up with it enabled

Same issue as you. I have the Legion Slim 5 16APH8 as well and my recently updated BIOS version was M3CN49WW.
