No OS found

[NotSmartMan]

I just reset my HP Pavillion to erase all data and restore the factory setting. On the reset it said that it would keep the OS on the laptop after the reset, but when the process finished, i have a screen stating that there is no OS and that a boot device is not found. What do I do?

Hi:

If the factory reset option left your notebook in that condition, the only suggestion I can offer, would be to clean install W10 as follows...

You can make a W10 USB flash drive installer with the Microsoft Media Creation Tool, using an 8 GB flash drive using another Windows PC, if your PC is not working.

https://www.microsoft.com/en-us/software-download/windows10

If you are asked to enter a product key during the installation process, select the 'I don't have a product key' option, and W10 will install and automatically activate once you are connected to the internet.

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

Select Download tool now, and select Run.

If you agree to the license terms, select Accept.

On the What do you want to do? page, select Create installation media for another PC, and then select Next.

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

Select which media you want to use:

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 reinstall the drivers and available software from the PC's support page.

Thank you so much for the help with installing Windows on the flash drive, but I am unable to put the OS on my PC when I plug the flashdrive in. Because it is on the “HP PC Hardware Diagnostics UEFI” there is no where to boot up the OS. Also when I do a Hard drive check, It says that there is no Hard Drive installed. Thank You.

You're very welcome.

That doesn't sound good to me at all.

It may be that the hard drive is completely dead, or the drive controller is bad.

You may want to try replacing the hard drive first and see if that fixes the issue.

Thank you for responding. It would be bery unlikely that my hard drive is dead seen as it was used very recently to the reset, but something could’ve happened during the reset. I will bring it to a tech center to see if some connection was terminated or something corrupted the hard drive. Thanks again.

You're very welcome.

Thank you so much for your previous help. I have just replaced the hard drive on my computer because the old one had corrupted. Now that I do have a hard drive on my computer, the windows 10 flash drive is not allowing me to install windows. It says it requires a GPT disk while my hard drive has an MBR partition table. I have no idea what to do now. Thanks.
