What does it plan when at start up your computer?

It probably ability that somewhere in the Bios there's an selection telling it to look for a subsidiary drive possibly as one of the locations to boot from. However it can't find it so it's telling you.



You might know how to stop this from happening by finding the boot option in your bios and removing the Secondary drive from the boot menu.
you enjoy a major problem return with to a free forum run by professionals to fix it - geekstogo.com - majorgeeks.com - mybleepingcomputer.com - many more around - reformat as a ultimate resort.
This just manner that a drive that was the lower drive no longer appears. If you only hold one physicaly hard drive (the device inside your case) later its likely to be your cd rom drive thats somehow be unplugged. More commonly tho, it could be an actual second hard disk which have failed.

Cd roms and harddrives use like peas in a pod communication methods in slightly elder computers, so it could be either. Best you can do, is cause sure everything is connected inside (if you have never done this in the past, then try draw from a local computer shop to help you out, or a friend)



hope that help
As long as it boots you are ok. The BIOS is searching for the rock-hard drives in your tool and it is indicating that you don't have a subsidiary one. Many computers don't. As long has it finds a primary, and the primary works, you should be fine.
