Update windows 10 from 1809 to 20H2 error

[John_5645]

Hello,

I factory reset my laptop using my recovery media but when I reset it it goes to version 1709. I'm trying to update it to 20H2 but it failed, so I tried to update it first to 1809 it success like other said on the internet. When I tried to update it from 1809 to 20H2 it failed again. What could be the problem of that? Could it be the prerequisites of the windows version?

The reset sends the laptop back to its ORIGINAL state, not the most recent one, so it did what it was supposed to do.

MS has made LOTS of changes to Win10 since version 1809, so I am not surprised the update failed.

So, WHY did you do the reset in the first place?  Need to know because some of the reasons will now prevent you from doing any more Windows installations.

I reset it because it's laggy. Is there a chance to update it to 20H2?

This issue is often due to a failing drive.

So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the HDD (Hard Disk Drive): http://support.hp.com/us-en/document/c00439024

If not, to check the HDD you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.

If the drive checks out OK, then report that and I can provide you options for reinstalling Windows on your PC.

Please note that if your model has an SSD instead of an HDD, these diagnostics might not work properly.
