Windows 10: OxC1900101 - Ox30017 error while updating Windows 10 version 1909 to 20h2/21h1

I have tried to update my laptop running windows 10 version 1909. When I try to update it, it downloads the update, and reboots it and goes to the update screen "Updating windows xx% complete Your system may restart several times". It goes to around a certain percentage and during the first reboot, it shows me the logo of my laptop Legion and it just goes into a black screen and stays there forever. This is probably my 30th time trying to update. I had dual booted Linux along with this windows before, and I uninstalled it. I have all my drivers updated. Any help is appreciated.

Should I update to 20H2 or wait for 21H1?

Welcome to Ten Forums.

To go from 1909 to the next version, whether that's 20H2 or 21H1, is a major feature update that will install new system files and save your old system to a Windows.old folder. This can take up to an hour to install, whether you go for 20H1 or wait for 21H2.

The update from 20H1 to 21H2 however will then be a minor feature update, a small enablement package that turns on dormant features and installs in a few minutes, just like a cumulative update. I'd go for 20H2 now, the update to 21H1 will then be quick when it's released - plus it will be optional so you can wait to see if others report problems before deciding to update.

With any major upgrade, it is a wise precaution to make a system image of your current system before you start. Many here use Macrium Reflect Free for that purpose.

 

Issue(s) with 21H1 Update

The Windows update list of installed updates has always been a confusing & incomplete list. I don't think you had a problem at all.
