Triple boot with existing Ubuntu and windows7.

Asked by bhaskar

I want to make my laptop with triple boot with existing Ubuntu and Windows7. I am planning to install Fedora/Slackware for my triple boot and the existing two OS(Windows7 and Ubuntu) are in different partitions. I have one more partition left unused in my laptop and i want to use the new linux in this unused partition. Please give me some suggestions for new linux installation because previously i tried and lost my ubuntu from laptop and again reinstalled it(for me time is most concern now). So please give correct procedure and explain the philosophy for triple boot how it works in any computer. you can tell me is it possible for quadraple boot and so on in any system without problems.

You will need to resize the existing partition to make space for the new OS, you can then install to the free space. Be sure your backups are up to date in case of catastrophe.

Partition table entries are not in disk order

The above message shows my partition details and how can i install another OS that mean can i install like dual boot or there any other process inorder to skip from catastrophe. Previously i tried like dual boot installation because of that catastrophe happened. So please tell me the cautions so that i can get rid of catastrophe.

OS you want to install will ask you during installation on witch partition you want to install.Select partition you know it is unused and put new OS there.

When i try to install Fedora OS and the installer is always saying that it wants to delete existing ubunt 11.10.
I don't want to loose my Ubuntu because it's my main linux OS and i was installed important applications in it.
And the same is happening with openSUSE and why i am getting this problem and because of this most of my valuable
time may lost. Please give me the solution and for that i will be very thankful to you.

If you resize your Ubuntu partition, you can tell the fedora installer to use the freed space. You can reuse the swap partition you use in Ubuntu in Fedora to save having to make another swap and save space :)

Thanks for Community members and i finished install fedora 15 by not installing boot loader for fedora separately. And the Ubuntu grub has taken care of the newly installed fedora by sudo update-grub from ubuntu terminal.Now i am able to swtich over on triple boot.
