It does look like your storage controller got switched to raid moda. Some ai generated slop-fix:

Your storage controller actually is visible in the lspci output, but it is currently hidden inside a RAID cluster.

Look closely at this specific line from your list:
00:17.0 RAID bus controller: Intel Corporation Comet Lake PCH-H RAID

Why Your Drive Seems Missing

• Intel RST Active: Your motherboard BIOS is configured to use Intel Rapid Storage Technology (RST) RAID mode.
• Controller Hiding: When RAID mode is active, the Intel controller intercepts individual NVMe or SATA drives.
• Linux Limitation: The standard Linux kernel cannot see individual NVMe drives behind this specific Intel RAID controller without configuration.

How to Fix It

You need to switch your storage controller from RAID mode to AHCI/NVMe mode.

1. Reboot your laptop and enter the BIOS setup (usually by pressing F2, F12, or Del at startup).
2. Locate the Storage Configuration, SATA Mode, or VMD Setup menu.
3. Change the setting from RAID or Intel RST to AHCI (or disable VMD).
4. Save and exit. [1]

Sorry, I think my reading comprehension was shit there… I got fixated on rescue usb not seeing the disk.

No, I wouldn’t expect it to be a bad port if grub is loading (and the grub partition is on the same disk). Bios not booting at all with disk removed is strange too, I’d expect it to just boot the usb if that were plugged in while disk is not.

You said usb rescue lsblk doesn’t list the disk, guessing it doesn’t show up under /dev/disk/by-id either? lspci? How about with a windows install usb, does it see the disk?

Like others said, sounds like hardware. But before you toss the drive, you said SSD, if it’s an ssd try different cables connecting to different ports. If it’s nvme try reseating it at least, moving it to another port if you have a 2nd. Just saying that sometimes ports and cables fail, so make sure you rule those out before losing hope.

Also possible it’s a bios thing, like maybe the port itself on got disabled in bios or controller got switched to raid mode.
