Laptop boots up but occasionally gets "Boot Device not found, Error 3F0"

[sinanf]

Hi,

This problem started a few months ago when my laptop was running Windows 10. I usually put my laptop to sleep to preserve ongoing work, and it started giving me the error "Boot Device not found" after restarting with a blue error screen. But it allows me to boot up normally (and use the laptop as usual) after exiting the Windows Diagnostics screen. However now it happens sometimes even when booting up normally.

I have done most of the fixes I have seen online. The diagnostics test (Memory and Quick + Extensive Hard Drive) all returned positive. I have reset BIOS settings to default, edited the bootup options to boot on my SSD first, updated my BIOS, and even tried booting up on Legacy mode. I also tried opening up my laptop and removing the SSD and putting it back in again, just in case it was loose. But the issue still persisted.

I have tried also tried the bootrec commands in Recovery mode, which all were successful. Furthermore, I even reset my laptop, updated it to Windows 11, and then did a clean install of Windows 11 with a bootable USB. It's not as if the laptop doesn't work, it boots up normally, but it keeps getting the Boot Device not Found error.

I have done multiple hard drive tests and all of them show that the drive is healthy. So, at this moment, I am just confused as to what is causing this issue and how to resolve it.

Please let me know if you require any more info.
