Error 0x80300002 on Windows indicates a specific system issue.
You're just beginning your PC build and everything seems to be working well, yet installation is failing with that specific error. The message suggests the Windows installer couldn't find the correct location for the drive, pointing to a possible issue with the hard drive's path or permissions. You've checked all four SATA ports and even swapped cables without success, which indicates the hardware setup might be sound but the installation software isn't recognizing it properly. The BIOS confirms everything is recognized, so the problem likely lies in the Windows installation process itself—possibly due to a corrupted installation file, insufficient disk space, or a mismatch between your drive and the installer's settings. Consider trying a different installation method, such as using a USB installation media, or reaching out to Microsoft support for further troubleshooting.
No optical disk or USB drive is being used for the installation process.
No additional SATA or USB devices. The only connection is a USB keyboard connected to the computer.
It seems you're facing a limitation with testing your HDD and USB. Creating a new bootable USB could be a viable solution.
