I just built my first computer and was trying to install Windows. I got to the installation screen after preparing a USB drive, but when it prompted for an internet connection, I couldn't type anything in the command window. I was able to open a command prompt using Shift + F10, but still couldn't type. So, I used another USB to load MSI drivers in hopes of setting up the internet. After some time, it restarted but then everything went south. I ended up seeing a recovery screen that tried to boot itself, but it got stuck saying it would wait 30 minutes to try again. I attempted to clean it manually by removing some files, and now it barely turns on. I see a brief "Pro Series" screen with a spinning wheel, then an error message saying "your PC ran into a problem. We'll restart it for you" with an inaccessible_boot_device(0x7B) error. When it restarts, the tower powers on, but nothing shows on the screen, and the BIOS screen flashes by too quickly for me to access it. What did I mess up, and how can I fix this?

Have you tried recreating your Windows bootable USB using Rufus? Make sure to go through the advanced options and set it to remove the requirement for an online account. It might help you get past that installation screen.

I initially tried splitting the files using 7-Zip, but I switched to Microsoft's Media Creation Tool for the USB. If I erase the current files and restart with Rufus, do you think it will properly load this time?
