Configuration parameters How to install two Linux systems

Some time ago, old students were doing django programmers in Beijing! I asked a few questions curiously! Ask him what system he is, he said fedora8 and fedora9. I am very surprised! Because this broke the stereotype thinking! Have heard that the installation of dual systems (win and linux)! But I have not heard of the two Linux systems! So I feel that I am quite sure to try and settle down!

First of all, a 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> Fedora-9- Put the i386-DVD.iso file in the root directory of a Windows Fat32 partition ((hd0,4)), extract the isolinux directory in the iso file to a more directory (hd0,4); <2> into the Fedora 8 Linux system Add the following to the file /boot/grub/grub.conf:

title install linux FC9root (hd0,4)kernel /isolinux/vmlinuzinitrd /isolinux/initrd.img3.Restart the machine and select [install Linux FC9] can 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 represents the hard disk, whether it is IDE or SCSI are represented by hd, 0 means the first hard disk, 4 means the fifth partition ; 2. If Ferus9 is selected during the installation process, 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.
