Installing two Linux operating systems on one hard disk

One hard disk has Fedora 8 Linux installed, and the grub boot management program is installed. Now install Fedora 9 in the

free partition of this hard disk. The operation is as follows:

1. Put the Fedora-9-i386-DVD.iso file in the root directory of a Windows Fat32 partition ((hd0,4)), and the isolinux directory in this iso file. Extract 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 source, select the hard drive.

Description:

1.(hd0,4) is the number of grub on the hard disk partition, hd stands for hard disk, both IDE and SCSI are represented by hd, 0 means first Block hard disk, 4 indicates the fifth partition;

2. If Fedora9 is installed, if you choose to update grub, grub's boot selection menu will be based on Fedora9. 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.

3. A hard disk to install a second Linux system, there is a new advantage is that it can share the swap partition.
