If you are here chances are you already know about the FDISK command ..or else you wouldn’t have DOS installed anyway.
FDISK is used to setup a partition to accept DOS on a hard drive.
Like many DOS commands FDISK has Command Line Switches that can be used with the FDISK command.
One of these is very useful and used to re-create the master boot record. It is the /MBR switch. This is useful in the event of Master Boot Record corruption.
It would be used like this:
C:\> fdisk /mbr
I know this works on the DOS versions that came with Win95 however I have not tried it on version prior to this.
