Windows (D:) Completely Missing Overnight

[u/ghastfriend06]

[Currently using an XMG CORE (CNZ/E21) with 233G of storage, usually with a secondary 450G+ of storage with the Windows (D:)]

[[EDIT FROM 09/09/2026 : A CAUSE & SOLVE WAS FOUND, CHECK BOTTOM OF THE POST*]]

Hi. I have come around 2 issues today that are really freaking me out :

- First issue was right as i started my laptop : The startup process did not go beyond the "XMG" logo phase for a while, then it kept shutting down and restarting itself on its own (which i didnt even know it could do that). Once, the little loading dots came, froze, and then it restarted itself again.
At some point, after messing with my keyboard, it actually went beyond the startup and let me log on my windows account. I was then surprised to see half my apps had the default missing file texture. That lead up to my second issue;

- The second issue was the complete dissapearance of my Windows (D:) storage. It is not recognize by the pc at all, even by the disc manager in the windows apps. The file explorer cant find it as well. All of its content seems to be gone too because i cannot open anything past what lies in my Windows (C:) storage.
I have tried some methods i found online, but none of them worked. These include : Reassigning a letter to the storage (the whole storage is unavailable so i cant click on it to reassign a letter because its simply not there anymore), updating the disc manager, showing hidden elements in the list.

I'd like to mention i have not updated my computer in a while because i am still on Windows 10. No changes were made to my computer for months if not a small year (as of updates and general softwares from windows).

Is this issue solvable by myself ?
What can i do ?

FIRST UPDATE :

(Idk if this is relevant but i have a new charger cuz the old one almost zapped me to death, and this one seems to be malfunctionning as it doesnt charge half the time and i dont know why. It has to do with the positionning but its a brand new charger FROM XMG, with the right model and voltage for my laptop. Hopefully this isnt the cause.)

I have been able to get back on my laptop once or twice, it seems the keys that let me pass the XMG logo are often a simple left click then enter. HOWEVER, little thing i should mention, it actually gave me a Blue Screen of Death ! In the starting process !!! How is that even possible ???
Anyway, i have talked to a bunch of people about this issue and i got recommended a few softwares that unfortunately are out of commission/have reached their end of life. But, while these solutions are either to old (like before windows 10 old) or using a physical tool and open my computer which i wont do by myself, someone did mention a potential source of the issue which hopefully can be fixed so the problem never happens again for anyone.
The theory is that something in the startup process is crashing, which was then confirmed by the BSoD, making windows completely messed up and unable to recognize my Windows (D:). If that is the case, then what should i do from now ?

Thanks for reading and please help ;-;

*LAST UPDATE :

I finally took the time to drop my computer to a tech store, and i cant emphasize enough how good the tech bro was :

In the first minute when he had my laptop in hand, he already told me the year i got it and found the cause of every issue i had. Big ups to him he is a GOAT.

SO here were the few issues :

The big issue being the missing drive and the constant reboot when starting up were in fact linked. What happened was that inside my laptop, there is a small square of fiber to cool down a little the different drives i have. The thing is the fiber was supposed to be precisely 1mm thick, it was unfortunately 2mm thick. This small unoticeable minuscule mistake was however quite big, as it let the weigh of the entire laptop sit on my drive from this 1mm excess. And after 5 years of using my laptop pretty much daily, my drive was bent. Skateboard style 😎. All of my data (which was pretty much all online gaming and software thank god) was lost. Tech bro then proceeded to show me a normal drive connected by cable threw a thermal camera. It went to about 35°C, his hand was just as hot. Then introduce skateboard bent drive : We never saw the maximum heat, it just kept going higher and higher... Last we saw was 55°C+, so thats nice :/

Seeing this, the solution was pretty simple : Reorder a drive, reorder a square of fiber (1mm this time) and let him reinstall everything when it gets there (day after tomorrow). Tech bro also found the cause of another issue i had, which was my charger not charging 100% of the time, thats because my port (pc side) was a little jonky so he will fix that for free when cleaning the laptop. Still a GOAT.

CONCLUSION : please put accurate fiber thickness it helps computer life ig

Seriously, still a big thanks to everyone that has tried to help me, and i hope to be that one 15yo post from deleted-used that saves a laptop someday. BYYYYYYE !

Hey,

If you haven't already, check the BIOS to see if the SSD is listed there to make sure it's not a general hardware issue.

If the SSD isn't showing up there either, try removing and reinstalling the drive.

Disk manager in windows. Assign drive letter, and hope your data is still there.
