Why oo you want to format the C drive, you would not be able to do that. Why dont you try installing some antivirus and try to fix the virus.

In case you still want to format the hard drive and in the process remove the OS, you would need a bootable cd / DVD for the OS. You would need to start the process of re-installing the OS

First change the first boot device in the bios DVD, then insert the bootable CD in the CD Drive, restart the computer and follow the screen instructions, you would get an option to select new installation or repair the existing installation. Please select new install.

Then you would get he option to select the partition to install the OS. select the desired partition.

Then you would get the option to format the selected partition. select the disered option.

and follow the screen instruction an complete the installation.

How to Remove virus from Pen Drive/Flash Drive?


Steps To Remove Computer Viruses Using Command Prompt:

Step 1. Click on Start and type cmd. Now right click on the cmd icon and select run as administrator. Running the command as administrator is important as you need to access the system files which are not usually visible in guest accounts. Now command prompt window will open, now select your drive from which you want to remove a virus.


cmd-1-ut2cqzhdo2jgpvt0ug4dvtv0-4-5.png

Step 2. Let us suppose your USB has a virus and your USB drive is F. Type "F:" without quotation on Command line. cmd-2-ut2cqzhdo2jgpvt0ug4dvtv0-4-9.png

Step 3. Now the C: will change to F: Now you need to type "dir F:" in CMD and hit enter. It will show you the directory of F drive. cmd-3-ut2cqzhdo2jgpvt0ug4dvtv0-4-14.png
Step 4. So now type the following command to show all the hidden and system files on your USB drive. Type "dir F: attrib -s -h /s /d*.*" without quotations and press enter. Typing this command will explore your selected drive and will load all the files including hidden and system files on your drive.

cmd-4-ut2cqzhdo2jgpvt0ug4dvtv0-4-20.png
Step 5. In this window you will notice unusual file.exe and extention if your computer has been infected with a virus like the dreaded autorun.inf virus. Rename it using this command line rename filename.extension new filename. Usage > C://rename autorun.inf (new filename)

cmd-6-ut2cqzhdo2jgpvt0ug4dvtv0-4-27.png That's it! Now you can identify all the viruses in your PC and USB and delete them without any help of anti-virus software. You can delete the autorun.inf by typing in the command "del autorun.inf" or del :"yourfilename"

I need to restore my computer without disc, what should I write in command prompt?


To access the System Restore Gui from command prompt you will need to type in rstrui.exe
OR
%Windir%\System32\rstrui.exe

Other Thoughts
--------------
If you are experiencing Boot issues you will need to install a boot manager. If your system is missing a file or a file is broken, you may need to replace that file with a working version that's compatible with your OS Version.
