Add new OS - Three questions


Hi Everyone,

I am still learning quite a lot daily, but want to go even further now with a new, more challenging distro while keeping my current setup (dual boot on two separate SATA drives Fedora 4 and WinXP.) In this regard, I have three questions if someone would be kind enough to help me with.

1. After adding the new partition (to the windows drive is my plan), do I edit the Grub.conf file BEFORE installing the new OS or AFTER? I have read conflicting views.

2. I am absolutely thrilled with Fedora Core 4. It is easy to use and far more advanced that any Microsoft product I have ever used, so I will be keeping it. I want to add one of the more "challenging" distros for the purpose of advancing my learning. Would someone be so kind as to recommend an "advanced" distro that will provide that learning challenge and be easily bootable with the other OS's I have. I am leaning toward Slackware, but would love to know differing opinions.

3. Would someone be so kind as to provide me with an example of the entry I would use in my Grub.conf file to be sure that I don't end up not being able to boot anything after installing the new OS.

Any help would be greatly appreciated.

Bob

1) I think after.
2) Slackware is always great choice but it isn't the only choice, read around and check distrowatch.com to find what you want.
3) I use lilo.

For number 3, post back the details for where you intend to install the new Linux OS. I tend to configure grub after I have installed the new OS.

Thank you for the reply. I intend to install the new Linux OS on the first drive (in Linux sda0, which shows up in my grub.conf file as hd0.) It is a 160GB SATA drive with WinXP on it. I plant to use about 10GB for the new partition. Obviously, the the grub loader is on sda0 (where MBR would have been). I have studied my grub.conf file and there are two kernels (both FC4, 2.5.11 and 2.6.14) and WinXP. Linux resides on sda1 (an 80GB SATA). I believe I need to know the kernel information for the new OS before I install (at least that what googling the subject has suggested.) Then, if what others have said is correct, I can add the new OS by adding something like the following:

title Slackware (or whatever else I choose)
root (sda0,1)
kernel /boot/vmlinuz-(whatever kernel) ro root=LABEL= quiet
initrd /boot/initrd-(whatever kernel).img

Is this the type entry I would use? Do I simply add this to my existing FC4 grub.conf as a third title entry?
Do I change any of the /SBIN/ binaries or does the installer do that?

I don't want to damage the setup I have because I have worked a long time to get it to where iit is. I just feel like I could learn a little more with a more difficult distro.

Thank you in advance for your help,

Bob

A quick correction. When I referred to the two kernels, I meant 2.6.11. The 2.5.11 was a typo. Also, when installing the new OS, I assume I omit the step to install a bootlader, correct?

Thanks

Bob

Yes you have to skip the section to install a new bootloader. To find out details about the new OSes kernel, just mount the new OSes root partiton in a directory on your old OS and cd to its /boot. If grub refers to sda as hd0, then I think your grub entry should be something like,
Code:
title Slackware
kernel (hd0,1)/boot/vmlinuz-(whatever kernel) root=/dev/sda1 vga=788 ro
Slack does not use initrd images by default so you won't need that. All you would need to boot Slack is to add the new entry to your FC4 grub.conf, no need to change anything else.
