How to replace the hard drive?

Depends on cause of the failure.

Try booting and hitting F2 to get into diagnostics, check drive.

If there was a Windows update that included a BIOS update - this may have reset BIOS options such as UEFI - try booting to BIOS by hitting F10, and see if boot options are UEFI or Legacy - if UEFI, try changing to legacy - save and restart - if it boots ok that was the issue.

That model came with a HDD or SSD or possibly a HDD/SSD hybrid drive.

Hybrid drive - depends on which part failed. If it was the SSD then you may be able to remove it and see if laptop works without it, as data would be on the HDD. If not, HDD may have failed.

If drive has failed and you want to retain data vs a fresh install? Retain data, clone to new 2.5" SSD of same or larger capacity - I usually do this in another machine where I can connect the old and new drives and clone using clone software. If fresh install - create Windows USB installer, install new drive and boot (F9) to the Windows USB.
