Windows suddenly dissapeared

[ShWatson]

Hello, i have windows 10 and i was on my pc. Suddenly it says: Your windows has problem and needs restart. (Or something like this). When i did restart besides windows, gigabyte sofware popped up. And i don't know what is the problem. Also right before this i connected my cd player to pc. Thank you for help. (Sorry for bad english)

When i did restart, the gigabyte thing popped up on monitor. Its like when you get new pc and u turn it on and it doesnt have os system yet. And when i did restart again still the gigabyte was on.

Have you try unplug your cd player and restart see if it works?
boot into BIOS and see if it list your hard drive there.

When i start my pc it says: ,,No boot device detected" or ,,Reboot and Select proper Boot device or insert Boot Media in selected Boot Device and press a key

Reset CMOS, it may fix your issue. Maybe something is wrong with the boot order after you plugged your device

Did you have any USB flash drive plugged in? unplug all usb devices.

I didn't have any usb. Now i do, im trying to install windows but when it ask where do i want to install it it shows me only drive 0 partition 3 and it cant be installed on that drive. I cant do anything.

from installation select advanced custom > select drive 0 and delete all the partitions you see there.
