I want to install ubuntu , without it touching my MBR. I plan to install ubuntu 12.04 on a particular ext3 partition and grub on the PBR of that partition.
From this page: https://help.ubuntu.com/community/WindowsDualBoot
If you have a problem with changing the MBR code, you might prefer to just install the code for pointing to GRUB to the first sector of your Ubuntu partition instead. If you do that during the Ubuntu installation process, then Ubuntu won't boot until you configure some other boot manager to point to Ubuntu's boot sector.
So it tell me what I have to do. My question is how do I do this ? I am guessing I have to
- grab the alternate install disc
- choose manual partitioning
- it will ask me to install grub and I have to choose the partition instead of the MBR .
- edit boot.ini to add ubuntu . I am on xp.
Are these steps correct ? Please tell , I am asking because I really don't want to screw this up. Also are there any other gotachas I should keep in mind ? Like updating screwing up the MBR ?
Edit: One question: in the alternate install CD , where exactly is the option to install grub in PBR ?
Edit2: why does anything I am trying to do has a bug associated wit it .
