When You start your Computer You got a massage , reboot and select proper boot device or insert boot media in selected boot device and press a key . like that on your computers screen :-

Main reason of this error is there is no boot device is inserted or selected into your computer .

In bios setting you will check that hard disk or other device is connected or not its look like that :-

In this picture we can see that  WD Hard Disk is connected. 

if its connected into yours computer then you find boot or boot setting in bios setting .  its second last option in last picture.

In boot setting you will change the 1st boot device to Hard Disk .

into this picture floppy driver is set 1st boot device .Because of this reason ERROR massage reboot and select proper boot device or insert boot media in selected boot device and press a key is showing up.

After changing 1st boot device to hard disk save setting by pressing F10 .
