I've really loved Fedora Core 4 given free in Digit. But my problem is I am not getting how to uninstall it. I've got only 40GB HDD so i decided that i'll install linux later after upgrading. I've already read in the forum that you have to give fdisk /mbr and than format the drive having linux and reallocate the space. But thing is that i dont know where to type that fdisk command. Please somebody give me a highly detailed uninstallation of Fedora Core 4 without effecting windows.
