ROG Strix G814JI BSOD and boot device missing

[Saviant0]

While watching a YouTube video and working, the laptop started to not respond to inputs, and then I got a CRITICAL_PROCESS_DIED BSOD. I wanted to look at what's wrong when it rebooted, except it didn't. Now when I boot it, it says "Checking media presence..." and then brings me to the UEFI, where I see no boot device at all. Considering the all other issues I had with the device (keyboard locking up after sleep, battery light sometimes blinking orange and not POSTing, and now this), it's safe to say that there's something wrong with my unit. Luckily I have some more months on my warranty, however right now I'm in my exam period, I have projects in mind, I'm not home and the next 3 and a half days in my country is national holiday, which means I can't even buy a replacement disk. It's the worst time for a such thing to happen basically. Are there any troubleshooting steps I can try to get the laptop to boot again, even if it's for a short time?

Note: I didn't upgrade/add/replace the original storage device. I only added a 16 GB ram as extra, and that's the only upgrade I've done.

Hello,

Is it a case that you need to access files on the drive or just need the laptop working?

If just working there are bootable Linux based operating systems, assuming the laptop is fine these will get it usable and you will be able to go online.

If the drive is ok and the issue lies with the NVME slot, take the back plastic casing out, remove the nvme drive and try it in the other slot, inspect for any signs of damage first, like burning marks..

Ok well, this is weird.
I'll update the post if it was something else, but I thought that disk was dead at first. Later on it booted by luck and I checked the SSD health, 98%. So nowhere near failure. Then I wondered if the disk was somehow loose in its place since I noticed the device giving the BSOD when I lift the device from the left. I opened the back panel and reseated the NVMe drive (some of the contact pins were barely visible from outside before reseating) and now it no longer happens. I'm not even sure how it became loose as before today I never even touched the pre-installed NVMe drive.
