What are you using to post with ?
I assume that's a Win 10 install USB ?
If it is, boot up with it again, go to the Advanced options and select Start-up Repair to see what that reports.
If it reports that it is unable to fix then select Command Prompt and enter these cmds -
bcdedit |find "osdevice"
For clarity that is a Pipe symbol before find.
Hopefully it will give you a partition letter.
If it doesn't or gives you an error message then you will need to perform a fresh install.
If it does then using your partition letter instead of the X I have exampled and enter chkdsk X: /f
That may report that it has made corrections to the file system, but primarily you are looking to see if it reports any KBs in bad sectors - hopefully it won't but it needs checking.
If that comes back clean then enter these cmds, again using your partition letter instead of the X I have exampled.
dism /image:X:\ /cleanup-image /restorehealth
sfc /scannow /offbootdir=X:\ /offwindir=X:\Windows
Enter exit to close the cmd window, remove the USB and select the option to continue to boot to see if it does.
Let me know how you get on.
