Windows 11 Unable to update windows on my Acer Nitro 15
I am currently on a Nitro ANV15-51 currently on version 23H2. Last night, I noticed it was downloading 25H2, but it was stuck at 0%. I verified the connection to the Windows services, and everything seemed fine. I verified the integrity of my Windows installation, and everything was ok. I flushed my DNS and cleared my cache, but it still wasn't working. I ran the Windows Update Troubleshooter, and it acknowledged that there was an issue that it claimed to fix, but the update still wasn't pushing, and when I would run the troubleshooter again, it would say the exact same thing.
Next, I downloaded the Windows 11 Installation Assistant and tried a fresh install. It got about 78% through before it froze and stopped. I did some more digging and discovered my Intel drivers were a year and a half out of date, so I updated them and tried again. It got to about 60% before it gave me a pop-up stating that Voidemeeter drivers were blocking the install, so I removed them. It completed the install and got to the point where it restarts. It restarted roughly 3 times before force-aborting, giving me the failure code 0XC1900101.
I went ahead and manually updated my BIOS and tried the Windows 11 Installation Assistant again. Same issue.
I discovered a chunk of my drivers were roughly 2 - 3 years old, so i updated all of them manually using the downloads from the Acer website and ran the installation assistant again, but after waiting, it did the same thing as the first time.
Between all of the waiting and searching, I've put about 12 hours into bug-fixing this computer, and im genuinely at my wits' end trying to solve this. The only thing I can think of doing now is installing Windows onto a thumb drive and factory resetting my pc, but Im a student and I have tons of important files saved, and it would take ages to back it all up, so I would prefer to avoid that. Any help would be greatly appreciated.
