Windows 10 (re)boot.

Hello,

When I (re)boot Windows 10 Pro version 1804, first of all, a black screen appears asking which OS to start up and after choosing Windows 10 (the only one mentioned) a blue screen appears with startup settings and asking to choose a F-key. With F8, the boot process continues and W10 is starting.

What does this mean and how to solve this issue ?

Thanks in advance for your reply.

Best regards.

Open a command prompt (Admin) by clicking on the start icon, type command, right click on Command Prompt that appears at the top of the list and select Run as Administrator. Then in the Command Prompt (Admin) window that opens, run the following command:

bcdboot C:\Windows
exit

See if that fixes it.

Thanks.
Only the first black screen still appears for one second and then W10 starts.
Best regards.
