Disk problem

What caused the problem in the first place?
Power glitch? Upgrade to windows 11?
Microsoft or HP update? Add a new device, memory, etc?
Have you run diagnostics?
Tap the ESC key after powering on and run at least one pass through memory and disk diagnostics.
Do not attempt any repair or upgrade if disk or memory is faulty.

You have cloud recover and COULD restore to factory conditions

If desired, you can restore your pc to factory conditions by going here and using a 32gb flash USB.

I assume you may want to save documents

 If the disk is bad then replace the drive and use the factory restore above.

If the disk is good then try a repair install of windows as discussed in "method 5"

https://www.laptopmag.com/articles/repair-windows-10

except use windows 11 if you have 11 get it here

make sure you select the option of repair and to preserve documents.

You may want to try method 1, the "system restore" before method 5

If you have trouble getting into those blue diagnostic menus then use the win10/11 mentioned earlier and select repair instead of install.
