Question on reinstalling windows

I usually wipe HDDs and SSDs before doing a clean install, puts the drive back to its as-shipped condition then let Windows partition and format as it needs based upon the BIOS. I use the MCT/Media Creation Tool to get both editions on Bootable USB and the .iso file to create the Bootable DVD. Haven't had problems with Win10 getting necessary drivers and usually the computers are what I've rehabbed so no warranty support [sent 4 such Notebooks to Honduras as part of a Vision Beyond Borders mission].

"Will my UEFI partition be built back again" Yes. Windows creates the specialised partitions it needs as well as the main OS partition during installation.

The Clean install procedure includes wiping and then rebuilding all partitions on the disk so you don't need to do anything special. Just follow the instructions in the tutorial

You'll be able to download your HP utilities & HP hardware drivers again from the HP support site.

It is worth including both these in your preparations:
1 Make a new system image & test its boot USB so you can recover if disaster strikes.
2 Backup and Restore Device Drivers - TenForumsTutorials

You don't mention why you want to reinstall Windows.

All this 24th June stuff will turn out to be overhyped. Your reaction to the news when it is finally released will be, "Oh, is that all?".

I reinstalled Windows 10 on upgraded computers as well. My logic was not as clear as yours. I was doing the same things with the same applications but also kept seeing comments about "things" running "better" after a reinstall. That might well have been poor advice.

Providing you prepare decently, there's no reason to expect any problems from a reinstallation.

Do you know about system imaging?

Denis

OK. Understood.

Personally, I use system imaging. I don't know how to restore just the OS partition from a clone.
