Linux does not boot in dual boot system

[Urjita]

Hi guys!
I have a problem with my dual boot machine:
I have three partitions on my disk: First partition is used by 64bit Windows XP, second partitions for my personal data and third one is used bu ubuntu.
The problem is that I have to boot with the Ubuntu CD to have ubuntu boot up else it automatically boots XP. i tried easybcd but when I select ubuntu, it give me grub command prompt: "grub>"
Can anyone help me?

Hey!
Have you installed linux boot loader? I guess you did not installed the boot loader of linux that is why it does not take linux into consideration and XP boot loader takes control of the system! Try to install the grub boot loader which will be installed if you do not deselect it while installing linux...
All the best!

hey!
Thanks! but i have installed GRUB boot loader, as i know without it booting of linux is not possible hence i installed it in the same partition where i installed linux, that is the last partition. Could i have messed up something some where?
Help guys!

hey!
Yeah, you just screwed the linux that you installed, you must install the grub boot loader in the first sector of the hard disk [MBR]. Doing this will take over windows boot loader and grup will be the first boot loader, in the options it will show linux as well as windows. You can select which OS to boot... Do not install grub else where, because then if Windows is in the first partition it will be the controller of the OS selection and which i guess is not good for linux to boot...!
All the best!
