Hard disk 3f0 error

[Shauryam_Singh]

I recently downloaded windows 11 update and after restarting I get boot device not found. Please install an operating system on your hard disk.(3F0)

When I run ho pc hardware diagnostic -> storage test

I show that no hard drive installed.

I tried to restore BIOS settings but nothing helped.

Hello.

Your hard disk has failed and needs to be replaced. If you have warranty, contact HP support to sort it out.

If you are out of warranty, you need to buy and install an M.2 2280 form factor drive for your laptop. NVMe is preferable, but older SATA drives will also do, though they are somewhat slower.

And after that you need to re-install Windows and applications.

If all this sounds difficult, contact a local computer repair shop who can sell the drive, install it and also install Windows as well. If your old drive contains valuable data that is not backed up to Onedrive or elsewhere, contact a professional service for data recovery before using HP warranty services or disposing the old drive.
