Boot Disk If you would like to create a boot disk, select Yes and press Enter. You will be prompted during the last steps of the installation to insert a floppy diskette for boot disk creation. If you chose not to install LILO (for instance you have another OS present and don't want to change the way your system boots), you must create a boot disk in order to boot Red Hat Linux. Note: If you chose to perform a partitionless installation, you must create a boot disk. Without this diskette, you will not be able to boot into Red Hat Linux. If you lose or destroy this diskette, you will not be able to boot into Red Hat Linux.
