Windows 10: how to delete update/ reset computer? I can only ascess to the command prompt

After I update my computer to 20H2 from 1909, when I boot by computer, I can only go to BIOS or cmd, how to remove update from the cmd, and what is the command?

command prompt will not open in safe mode with command prompt

Would I just follow the same steps within safe mode after hooking up to the other system?

 

Deleting Hiberfil & Pagefile

You would have to move your Page File to a different drive to get rid of that file, however you can make is smaller by adjusting the size in Windows.

To get rid of Hyberfile.sys you need to disable hibernation by doing the following:

• Click Start, and then type cmd in the Start Search box.
• In the search results list, right-click Command Prompt, and then click Run as Administrator.
• When you are prompted by User Account Control, click Continue.
• At the command prompt, type powercfg.exe /hibernate off, and then press ENTER.
• Type exit and then press ENTER to close the Command Prompt window

Then you can delete the hyberfile.sys file.

 

Installation media boots to command prompt

I've just booted from known working install media to see exactly what it does when booting. The sequence of events is...

1. Windows logo on a black screen
2. circling dots appear beneath the logo
3. light blue 'Please wait' screen with circling dots
4. a command prompt window (very briefly)
5. the initial Setup page appears

Do you see steps 1-3? If so, it appears you have stopped at step 4, suggesting that something on the disc cannot be read.

Does the disc boot properly in another machine? If so, try cleaning the laptop's drive lens then try booting from the disc again.

If not, make new install media with Microsoft's Media Creation Tool, either as a bootable USB, on an ISO that you can burn to another disc. At Step 8 in Option One of this tutorial you can choose between making a USB or an ISO.
