Here is the tutorial I made with the info I got from budman7
It can help anybody including me and should be sticked
How to Triboot a Computer
Distro 1= Prime Distro example (Windows)
Distro 2= The 2nd distro to be installed, this can be any distro (This controls the bootloader)
Distro 3= The 3rd distro to be installed, this can be any distro
Things to do Before You Start
Run Defraging tools
Scan for Spyware
Scan for Viruses
These are good steps for Window's users and can be used in Linux also
This guide focuses primarily on the GRUB bootloader to Triboot
You can also use the Knoppix Live cd or the partitioner that comes with your distro these include Diskdruid in Fedora Core,Qtparted in SuSE and GParted (Gnome Partition Editor)in the GNOME desktop. There are also partition tools that you can use that do the same thing these include Parted,fdisk,cfdisk,PartitionMagic
Steps 1-6 can be skipped if you are using Knoppix or any other live CD's to resize and modify the partitions
Download A Copy of Slax
This is very important because this is the Live CD we are going to use to partition the hardrive to get it ready to Triboot.
Here is the site you can get it from in case you don't have it http://slax.linux-live.org/download.php
Then download SLAX Standard Edition
Additional software for SLAX is provided in the form of compressed modules. The usage is very simple, just add your downloaded module to /modules/ directory on the CD to include it in SLAX permanently, or use "uselivemod" command in SLAX to activate the module on the fly, while running SLAX.
Download these modules and follow the instructions above for Linux or If you are a Windows user download MySLAX Creator at
Step 1:Bootup the Custom Slax Cd you have made then make sure the computer can bootup the cd.
You can check it by going into the BIOS by selecting F1 at bootup then go to computer check and change it from there.
Step 2:Once Slax is running you must now Unmount all partitions.
You do this by going into My Computer you will then see all of the partitions.Right click on one of them it will then give you the option to unmount.Select it and it will then be unmounted you must do this for all of the partitions.
You must do this for all of the drives or else the computer can't be partitioned
Step 3:Click on the KDE logo then go to run application and type qtparted in lowercase then hit run
Step 4:This will startup QTparted,now you must choose which program you want QTParted to use The drive I am going to resize is a NTFS partition.
Step 5:Now we begin the process of resizing the hard drive
1.Select the /dev/hda for IDE or /dev/sda for a SCSI drive on the left, then you should see its info on the right
2.Select the NTFS partition and right-click on it, then select Resize.
3.Next you'll see the Resize Partition dialog.
4.Enter the size you want for your existing Prime Distro to be resized and then click OK.
This can be done in Gigabytes or Megabytes
5.After clicking OK you'll see an updated view of your partitions. Note that nothing has actually changed yet; you must select File then Commit to apply the changes.
6.Just click Yes on the confirmation dialog.
7.You'll see the progress dialog and when it's done click the OK button
8.Now Select File then Quit to exit QTParted
9.You should now boot into the Prime Distro it will then detect the partition that you have made but it will be unformatted.
Now boot back into QTParted the way you did before and Delete Distro 2 and the Swap Partition by right clicking it and hitting delete
Now you should have the Prime Distro and a bunch of free space.
Step 6:Out of the free space create 2 partitions.
Both Should be Unformatted
1 Partition for Distro 2
1 Partition for Distro 3
Unformatted means that no file system is currently on it.
When installing the Operating System it will give you the most common options which are Reiserfs and Ext3.
Also many distros support Custom Partitioning which will give you more formatting Options.
A file system is added to the computer whenever you install an Operating System to it.
Below are some examples of filesystems that can be formatted or resized.
Its also a good idea to add Swap if you have a low memory computer which will use the Swap as temporary ram also the Swap partition should be formatted as Swap.
If the swap is inside the extended partition, you will have to delete the swap first.
Step 7:Now Install Distro 3 by Booting the install cd as if you were going to boot Slax and Install bootloader to root partition.
Step 8:Install Distro 2 using swap already created from installing Distro 3 and putting GRUB on the MBR which will make GRUB the bootloader that is controlled by Distro 2.
GRUB can be put anywhere but for this tutorial we are going to be put on the MBR so Distro 2 becomes the bootloader.
When installing other operating systems
Distro 2 should now make an entry in GRUB for both the Prime Distro and Distro 3.
The computer should now be restarted I you will be shown the Distro 2 GRUB Bootloader which contains the Prime Distro,Distro 2 and Distro 3.
The computer can now Triboot
Make sure you don't put Swap for Distro 2 on the partition where you are going to install Distro 2 to. By default Distro 2 should make a Swap partition or detect a Swap that is on the computer and mount it.
For Installing new linux distros install to the partition so Distro 2 Grub doesn't get overwritten
A Big Thanks to budman7 for supplying the info and if you want a picture guide of using QTparted this site is very good even though its mainly used for Ubuntu but can work on any distro.The distro that they use is the System Recovery Cd which very out of date.
