laptop running on a different model than the model I bought?

[Rawbean1]

My OMEN Laptop is the model 15-ek0013dx. I recently had a booting issue where I left my laptop running over night and had woken up to a blue screen error that read "INACCESIBLE-BOOT-DEVICE" I was given a suggestion by a friend to reinstall Windows 11 onto the laptop since my laptop would no longer boot or allow me to reset it through the Recovery Options. After I reinstalled windows 11 (through a usb) I thought the problem was fixed because it booted up like a new laptop. But I noticed that all my disk space storage was gone, and it said that my storage was full out of only 26 gb. When I checked the model of my laptop it now says that it is an, OMEN Laptop 15-ek0xxx, is this the reason why all my storage in my disk space disappeared? The original model when I bought it had 526 gb but now it is all gone. I don't even have enough storage to install all the security updates that comes with installing windows 11. Is there a way I can fix this without buying new parts to replace?

The specs of your machine is

              https://support.hp.com/au-en/document/c06656951

It has  512 GB Intel® SSD which has 32GB of Optane + 512 GB PCIe® NVMe™ M.2 SSD on a single piece of hardware physically.

Some how you installed Windows 11 on the Optane component. Now your machine should have 2 drives: one 32GB and other 512 GB PCIe® NVMe™ M.2 SSD. If not the 512 GB PCIe® NVMe™ M.2 SSD could be damaged and you have to replace it.

You can replace 512 GB PCIe® NVMe™ M.2 SSD w/o Optane.
