OS disappeared after Windows 10 reset

[DarthMather]

Hi, yesterday my friend gave to me his HP Omen and we started to reset it with the Windows 10 built-in reset option (Start -> Settings -> Update & Security -> Recovery) to clean the pc of all his datas.

The process was quite long but in the end it reached the 100% : after this it restarted and it showed up this message "Critical

error detected - No partition found."

Then we tried to restart it several times but it always showed up "No bootable device" : the OS was completely deleted!

This pc was bought on October/2017 so it still has 1 year warranty, what should I do? The pc has some scratches so I'm afraid they will take the pc for 1 month (maybe even more) and then say that the warranty is not valid for that type of damage. Should I install Windows 10 from a pendrive or bring the pc back where my friend bought it?

Hi:

You will have to make that decision...bring it back, or clean install W10 yourself.

But if the PC was purchased in October of 2017, isn't the 1 year warranty expired?

We are well into November now.

Just note that if you clean install W10, you won't be able to try the factory reset option again, so you may as well delete all of the partitions on the hard drive and have the maximum space to use for storage.

To reinstall W10...Use the Media Creation Tool.  Make the 64 bit installation media.

You can make a W10 USB flash drive installer using an 8 GB flash drive using another Windows PC, since your PC is not working.

W10 will find the product key in the PC's BIOS, install and will automatically activate once you are connected to the internet.

Here are the steps to create the W10 USB flash drive installer...

1. Select Download tool now, and select Run.
2. If you agree to the license terms, select Accept.
3. On the What do you want to do? page, select Create installation media for another PC, and then select Next.

4. Select the language, edition, and architecture (64-bit or 32-bit) for Windows 10. You want 64 bit.

5. Select which media you want to use:
6. USB flash drive.  Plug in a blank USB flash drive with at least 8GB of space. Any content on the flash drive will be deleted.

Then you can install the drivers and available software from the PC's support page.
