Hi Nakyung_195,
I'm Paul and I'm here to help you with your concern.
Did you already try to upgrade using the Windows 11 Installation Assistant?
If not I suggest that you try it, you can download it from the link below.

Before installing the upgrade, do the following first.
- Remove 3rd-party antivirus program.
- Unplug any USB devices except for the mouse and keyboard.
- Update BIOS if it's available.
I hope this helps. Feel free to ask back any questions and keep me posted.
Hi Paul,
Thanks for informing me about the Windows 11 Installation Assistant as I haven't tried upgrade using the Installation Assistant. However, I am unsure if this will work as I've seen users with the error 0xC1900101 also failed to upgrade using the Installation Assistant. Also, I may have to consider before going this route as I'm kind of limited on bandwidth. Do you know what are the error codes I got mean? I've tried to search the internet and it seems like it's a driver fault. If this is true, then the Installation Assistant won't make any difference, as I don't have the idea which one is faulty, right?
Also, to add information, I am using a laptop, so I have tried to unplug the mouse before trying to install (using Windows Update, before creating this question) and it got stuck at a certain percentage. I don't have any 3rd-party antivirus program, and my BIOS has just been updated recently.
