Help with adding CentOS to dual boot

[Sladex]

I already had a dual boot with Centos6+Windos7 but I recently added Kubuntu 11.10 and now I have dual boot with Kubuntu+Windows but I want to have a boot with the 3 systems. How can I do this?

Re: Help with adding CentOS to dual boot

I am assuming you are booting from the blue Kubuntu bootloader, you *should* just have to run update-grub in a terminal, and look to see that it found the centos stuff, not sure what that uses as a boot loader.


Way too much info [https://help.ubuntu.com/community/Grub2]here[/url]

Re: Help with adding CentOS to dual boot

Yes, Kubuntu is controlling Grub. And OS are installed on:

Win7 - sda1
Centos - sda3
Kubuntu - sda10

I ran "sudo update-grub" done, but nothing changed Indeed I can see every partition in Dolphin except for Swaps (obviously) and CentOS partition.

Also I found an entry to modify the Grub on the like claydoh gave , but I though grub.cfg should not be modified, I think 40_custom could be modified but I'm not sure.

>>>
A sample entry for chainloading to another GRUB bootloader.

menuentry "Grub 1 Bootloader" {

set root=(hd0,3)

chainloader +1

}

Re: Help with adding CentOS to dual boot

so Centos was installed to a LVM?

and you dont know how to mount it .

did you do anything speshal wile installing Centos ....or did it make the LVM it's self?

anyway I know nothing about linux LVM's but I did find this which may help you .
http://linuxers.org/howto/how-mount-...rtitions-linux

if you manage to get in it and can get to the grub.cfg or menu.lst post it and we MAY find a way to boot it

nvm I could not test a new boot because I had to erase kubuntu to get more space for Centos and Oracle 11g
