Install two Linux operating system methods on one hard disk

A hard disk has Fedora 8 Linux installed and the grub boot manager is installed. Now install Fedora 9 in the

free partition of this hard disk as follows:

1. Put the Fedora-9-i386-DVD.iso file in the root directory of a Windows Fat32 partition ((hd0, 4)), and extract the isolinux directory in the iso file to a more directory (hd0, 4);

2. Enter the Fedora 8 Linux system and add the following to the file /boot/grub/grub.conf:

title install linux FC9

root (hd0,4)

kernel /isolinux/vmlinuz

initrd /isolinux/initrd.img

3. Restart the machine and select [install linux FC9] to open the Fedora9 installer. When asked to select the media installation When the source is selected, select the hard disk.

Description:

1.(hd0,4) is the number of grub on the hard disk partition, hd represents the hard disk, whether it is IDE or SCSI, hd is used, 0 is the first hard disk. 4 indicates the fifth partition;

2. If Ferus9 is selected during the installation process, the grub boot selection menu will be based on Fedora 9. It's best to update grub because Fedora 9's grub startup configuration parameters are different from Fedora 8. After entering the Fedora9 system, update the Fedora8 startup configuration parameters from the original grub.conf to the grub.conf file in the file Fedora9.
