Hey man, I don't know if you are still having trouble or not, but I had this issue after I reverted my PC from a W10/Hackintosh combination desktop. Needless to say, there was a plethora of issues with installation errors and such. However, this was actually the final obstacle for me to get past after everything else. Please note, that this will likely only work if your issue was the result of a strange boot sequence that favored a non-installation partition on a bootable USB drive (If you don't know how to do that, I can tell you; it's very easy, but you need a second PC to do it, if your current one is out). When it does that, it seems to properly run the boot manager, but the installation files are not being initialized.
1. Restart your PC (if you are in the black screen with the flashing cursor still)
2. If you know the key to enter your BIOS screen, start tapping it as soon as your PC boots up (Some PC's have stupid fast BIOS screens)
- NOTE: If you can't see what the key to enter your BIOS is, try tapping "F11" or the "DEL" key; Those two are the usual suspects.
3. Once you are at the BIOS screen, locate your BIOS boot order settings. (Mine was on the main page at the bottom, but everyone's will be different. Just Google your Motherboard's brand and model number followed by the words "boot order" or something)
4. When you find the boot order menu, manually select the drive with the Windows Installation files on it (For me, the word "UEFI" was added to my boot drive)
5. This load screen took a long time. I thought it froze on the BIOS splash screen for some reason, but it ended up loading the Windows 10 installer (albeit, it was very slow initially).
I think this may just be an issue with your computer preferring the wrong boot drive. This would be very likely to happen if you had a previous installation on your system because even though you erased the data, it really isn't gone. Since you can't see the boot manager files anyway, they are likely able to be accessed even if that data was supposed to be erased. Once you force the PC to use the proper boot device, it should load everything correctly. Hope this helps someone!
