No need to drive the disk without the reinstallation system method other than the optical drive!

        If you want to reinstall the system for your computer, but you don't have a drive, there is no CD drive! You can download a GHOST (recommended depth GHOST) online. If you download the ISO file, you can extract the GHO file inside. If you download the GHO file, you don't need it! Then download and install a MAXDOS tool (do not set a password when reinstalling the system)! Start now, restart your computer first, then press F8, select the MAXDOS startup item, enter the DOS tool, enter the "GHOST" command, it will enter the GHOST operation interface (GHOST will not be used? Then I can't help it!) Choose you GHO file (forgot to put it? Restart yourself into the system and see if the location is back!) Reverting to the system disk will automatically install it!
