1. Don’t forget that Fedora always need / (root) label to get installed, so change the other OS’s labels to something else as /1 or /12 or /123, etc. by using any partition software like paragon partition software or something else.
2. Change the menu.lst of the OS, which is in MBR, accordingly.

Now start the installation of Fedora 10:

1. Everything will be almost same as earlier installations, as first you have to create one ext3 partition and during installation use same swap space.
2. Bootloader, you can install in the starting part of the same partition, what you created just now. Otherwise it will get installed in MBR.
3. I installed the Bootloader in the starting of the same partition & finished the installation.
4. System will get Reboot.
5. Since Centos is in MBR, so it will get booted. Now edit the /boot/grub/menu.lst file by adding the Fedora as Chainloading, as we did for Solaris.
6. If in case, you installed the Bootloader in MBR, then after Reboot the Fedora will get booted. Now you have to edit the menu.lst of Fedora by adding other OSs as you did earlier.

Note:– After completing this section, I’ll discuss the issues regarding menu.lst, its different ways and problems & their solutions?” So, don’t worry and Keep Enjoying…

Note: If in case, you had not mentioned during RHEL installation about Solaris, even though you need not to worry. Let the system get booted in RHEL and edit this file /boot/grub/menu.lst
You need to just add the chain loader command for Solaris grub after the RHEL in menu.lst file, save it and reboot the system.

For Example (as in this case) :

#######################################
title Open Solaris
rootnoverify (hd0,0)
chainloader +1
#######################################

CENTOS 5.2 :-

Now we are going to install CENTOS in the continuty with Solaris & RHEL.

1. Create one ext3 partition in the extended partition, as we did for RHEL.

2. No need to create the swap partition, since we’ll be using the same swap space, what we created for RHEL.

3. Start installation from the Centos DVD.

• During installation label the created ext3 partition as “/” (root) and the previous one swap as swap.
• NOTE: Centos 5 + versions should automatically label the “/” (root) like “/1″ or “/12″ or “/123″, to differentiate from RHEL installation, which has already “/” (root) as label. If in case you want to install some older version of Centos, then better use any partition software like Paragon partition software to label this partition as something different than RHEL, like “/1″ or “/12″, etc. If you want to relabel the RHEL installation itself, then don’t forget to modify the menu.lst as per the same.
• Install the bootloader: You can do this in two ways–

1. Install the bootloader in the MBR itself and add the RHEL in the Centos’s menu.lst
2. Install the bootloader in the starting part of the Centos’s partition and add the Centos in RHEL’s menu.lst

• I installed the bootloader in the MBR itself, with advanced options.
• Check the list shown during installation and as per your bootloader installation select the default bootloader, remove others and add Solaris & RHEL, with their respective locations.
• Select other options as per your need, finish the installation and get rebooted.

4. After reboot, as per my selection to keep Centos as default, Centos will get started. Since the default time is 5 seconds only, so press any key instantly and then your all options Centos, RHEL & Solaris will get flashed on the screen. Select as per your choice and every thing should work properly.

5. Now get booted to centos and edit the menu.lst

• Change the default time of 5 seconds to any value, whatever is good enough for you.
• If any of the options was not working properly then check the menu.lst file and see whether all operating systems are proper or not. Mainly check the labels.

Note: I have tried my best, eventhough if you think that i should explain something in some better way. Please let me know—Drop your queries and suggestions

1. Hard disk can only be partitioned in four primary partition.
2. Solaris & Windows need primary partitions to get installed.

What we are going to do:
We are going to install the following Operating Systems on a “Blank SATA Hard Disk”:

1. Solaris 10
2. RHEL 5.3
3. CENTOS 5.2
4. Fedora 10
5. SUSE 11.1

Get prepared to start the installation:

1. Get all operating systems installation CDs or DVDs.
2. Don’t forget to keep one bootable CD or Floppy handy.
3. Get one bootable partitioning software’s CD, like Paragon Partition Software, Partition Magic, etc..
4. Here i am going to install all these OSs on 500Gb sata hard disk.

Note: You can boot RHEL5.3 from Solaris10 grub by modifying the menu.lst but you can’t boot Solaris10 from RHEL5.2 grub, directly. You have to chainload it.

SOLARIS10 + RHEL5.3
1. Create one primary partition (FAT32) & One big extended partition as per the number of linux distros you want to install.
2. Install Solaris10 in the primary partition.

• After installation this partition will be of its own type, solaris.
• Check whether installation is fine or not, Solaris should get booted on restart.

3. Now its the time to partition the extended partition, what we created in the starting itself.
4. First create a FAT32 partition to share the files in between Solaris10 & all other linux distros. Size of this partition you can keep as per your need.
5. Create another partition in the same extended partition as ext3 and swap.
6. Keep swap a bit large, say 1Gb, that is more than enough. We’ll be using the same swap for all linux distros.
7. Now install RHEL5.3 in the above created partitions(step6).

• During installation label ext3 partition as / (root) and swap as swap.
• Install the boot loader in the MBR with advanced options “ON”.
• Check the list shown during installation, make RHEL5.3 as default bootloader, remove others and add Solaris10 which is in /dev/sda1
• Select all other things in between whatever you want to install in RHEL5.3 or either use the default options.

8. After installation, it will get rebooted.
9. On reboot RHEL bootloader should start, default time is 5 seconds only, so press any key instantly to see the options.
10. You shuold see two options in grub menu, RHEL5.3 & Solaris10.

• On selecting RHEL, it will get booted.
• On selecting Solaris, its grub bootloader will get started. And from there you can start Solaris.

Remember: You can boot RHEL from Solaris grub but you can’t boot solaris directly from RHEL grub. So, you have to chainload first and then Solaris grub will get booted.
