I see the system process (nt kernel and system) using 100 CPU. I checked there is no windows update running.
then I restarted and checked the boot menu suddenly there was no floppy disk drive, realtek network lan and cd/dvd drive. previously there were 7 options and now there are only 4.
1. is it possible to change the boot priority order through nt kernel and system?
2. how to restore the missing 3 boot options?
