Reinstall win 10 on my notebook 15bs521nl

[ernestobubbi]

My hd broke. I have no backup and no restore disk.

I am thinking to buy a ssd. But i don't know how i can install the old operating system that was preinstalled on the broken old hd. Is it possible to get it from hp support center and which are the steps to follow?

Thank you for your support

You can use the Microsoft media creation tool on another PC to create a bootable W10 installation flash drive to reinstall W10 on the new drive.

Download Windows 10

Your notebook's Windows product key is encrypted in the BIOS so you will not need the product key to install Windows.

After W10 has completed installing, you can install the drivers and available software from your notebook's support page.

Below is the link to the service manual:

To boot from the W10 installation flash drive, have it in your notebook's USB port.

Turn on or restart the PC.

Immediately tap the ESC key to get the menu of options.

Select the F9 boot options menu and from that, select the USB flash drive and press the Enter key.

The PC should boot from the flash drive and you follow the on-screen instructions to install W10.

There are several guides for how to do this on the internet such as this one:

Thank you for the sokution. After some little tries i found the right way and i finally did the installation on win 10.

I supposed i could also install win 11. But with ny great surprise the tool provided by microsoft to vrrify compatibility of my machine told me the processor is not compatible with win 11. 

Can you assure about this reply?

Thank you

You're very welcome.

Glad you got W10 reinstalled on the new drive.

Regarding W11:

The minimum W11 Intel processor requirement is an Intel 8th generation core or newer processor.

Your notebook has an older Intel 6th gen core processor.

You can install W11 on your notebook and it should work fine, but you will need to use a workaround that bypasses the W11 hardware checks so you can install it.

If you are interested in installing W11 24H2 via an in-place upgrade on your PC as is, watch this video, which is the easiest way to do it in my opinion, and I have tried many different ways to do this during the last 3 years.

Download the W24H2 ISO file and use that (3rd option).

Download Windows 11

You can download the free 7-Zip file utility from the link below. The top line is for 64 bit.

You'll have to repeat this or a similar procedure each October when Microsoft rolls out the new builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.

Other than that, your PC will continue to get the monthly cumulative and other updates.

That's only a minor inconvenience to have continued OS support beyond October of 2025.

If things don't work right on W11, you have 10 days to easily go back to W10 as long as you don't delete the W1 upgrade files or the Windows.old folder.
