Factory reset an HP laptop that won't boot properly

When you get to Reset this PC, try Keep my files first. If the problem was a broken update or corrupted system files that's often enough, and you don't lose your documents. Only go for Remove everything if keep files fails or it still won't boot afterwards. And if it does come to the USB, HP has its own Cloud Recovery Tool you run on another Windows PC. You type in the laptop's product number and it builds a recovery stick with the exact factory image and drivers for that model.

Does it get as far as the HP logo? If so you can reset it without Windows loading. Press the power button, and when the HP logo shows hold the power button to force it off. Do that two or three times and Windows opens the blue recovery screen by itself. Go to Troubleshoot > Reset this PC. Pick Cloud download rather than Local reinstall, if the boot problem is corrupted system files the local copy is probably damaged too. You can also try tapping F11 right after powering on, that goes straight to recovery on most HPs. If none of that ever appears, or you get a 'no bootable device' message, it's likely the drive itself and a reset won't help. At that point you'd be making a recovery USB on another PC.
