Windows 10 reset stuck at 99%

Good evening,

Let it run for another hour or two, and if not, reinstall Windows 10 without formatting:

The principle is to create a Windows 10 installation USB drive and boot the computer from it to reinstall Windows without formatting.
Since the computer is frozen, it should be created from another functional computer.

To create the USB drive:

• Create a USB drive using Media Creation Tool: https://www.malekal.com/windows-10-media-creation-tool/
• Boot from it by modifying the boot sequence and indicating the USB drive or DVD: How to boot the computer from USB drive

Download the ISO file for example using Adguard: Download Windows ISO
Launch Rufus then indicate the ISO file
