If you're using a Windows computer it is usually drive C:/ You can find out by going to Computer or My Computer and right-click, then go to Manage, and finally Disk Management and under Status, it should say exactly which drive is the Boot drive.
A good general way to check regardless of what operating system you're using is to look at the BIOS settings when the computer is starting up and check the boot device priority.
Basically you would need an operating system. To elaborate, you will need a bootable image that can be loaded by a bootloader.
That would be your hard drive since it holds your operating system.
That would depend on what operating system you are using. Every operating system has its own tools for checking hard drive and file system consistency.
The operating system, basically, allows a user to actually use the computer. Without an operating system, it would be like trying to drive a car that did not have an engine!

intially when we install operating system , we are suppose to select the drive where we want to install operating system, by this first of all the drive would be completed formatted and operating system install in it , so completely in our hand to select the drive to insall operating system and c drives always comes as default option to install operating system , which we can change to other drive.....if you hav any other question email me at abdul_island@yahoo.com
In a UNIX type environment you need to "mount" a drive to logically attach it to the operating system. Before you use the "mount" command, the drive is just a hunk of hardware hanging out there somewhere and the operating system doesn't know how to use it. After you "mount" the drive it is available for read/write, just as you would expect with any computer drive.
Why is an operating system necessary ****************** Without an operating system, you would be staring at a blank screen.
You need to be more specific with the question. The operating system say windows uses a generic driver for the hard drive, so if the computer did not see the hard drive you would not see anything, because the system would not run and you would only have DOS.
Practically all of them have O.S's, as I doubt that most people will ever see one without some mac o.s on it or xp or vista on it. However, all stock machines that are loaded/downloaded/installed with programs/software,etc come without operating systems. I have seen my share of them, as I used to work for a computer store myself, though DOS is nothing to brag about, unless you are some nerdy IBM veteran that designed it.
Hardware And Operating System
It would have to be a BIOS-infecting virus, but since BIOS is protected from writing both by itself and by operating system, it cannot be modified. That is why many antivirus programs delete files when starting. Antivirus is loaded as kernel module so it starts before any programs. Virus couldn't be a kernel module, because it would need administrator privileges to be installed, and would be big and not really virus-like.
