Multiple OSs with GAG Bootloader
I'm new on here, and I'm in need of some help. I've been searching Google for a while now with no luck, and I haven't found a similar enough thread on here to help me out. Before we go on, I should probably point out that I'm a Linux newbie -- as many others, way too used to Microsoft's approach.
I've just purchased a new 500 GB HDD to install 6 operating systems on:
1) Scientific Linux
3) Linux Mint
4) Win XP
5) Another Win XP
6) Windows 7 RC1
I currently have two Windows installations on another HDD, which are multibooted with Partition Magic (which doesn't work with Linux -- a death sentence for any developer, IMHO).
I want to create a multiboot system, and I was thinking of using GAG bootloader for it. But my question is the following: in what order do I actually do these things?
I imagine the first step is to format and partition the new HDD -- the Linuxes to ext3 and the Windows to NTFS. I was thinking of using gparted on the System Rescue CD for that.
That should be simple enough, but where to from there? How do I access the right partition to install the required OS on it? What are the issues with GRUB or LILO? Do I need either at all when I have GAG?
I'm somewhat worried about this first-time thing, in case something goes awry and I lose my current data, which is why I want to have a clear idea of what I'm doing and what to expect.
I'll get the hang of Linux and all of this; I just need to get started! Any help would be greatly appreciated!
