In addition, even if Windows was installed on another hard drive, then system files, necessary to run the OS can be stored locally. In this case, the BIOS check will begin with it ( C).

It turns out that this is only necessary for future installations new system. Otherwise, you will simply make the computer unusable. Before this you need to prepare a little.

You will need another media with the operating system you plan to install. This method works on any version. I'll demonstrate it on Windows 8.
