hello sarath_5,

make sure there is no usb drive plugged in or there is no disk in disk drive. if has than first remove the usb drives or cd, dvd then restart the laptop.

try setting hard drive to first boot device from bios (F12 key to bios)
Have you made tried tweaking Boot mode - UEFI to Legacy mode? if it is set to uefi change it to legacy and set hard drive as first boot device then try restarting the laptop to see if it works.

and if this didnt work,try a different hard drive.

Hi there sarath_5,

Was your system working just fine before?

Just to add up to what Sourabhskv74 has suggested, you can just check the HDD is detected by BIOS at all. In case it is not, then it could have failed.
If your HDD is recognized by BIOS and it is the first boot option but you still get this error message, you can try to run start up repair.
