Fedora and Debian Dual Boot Problem

EliotK · 03-02-2005, 02:26 PM

Ok, I formatted my hd, installed debian sarge first, (via ftp), got it working fine and shit, then i install fc3, it doesnt dectect it properly, what i would need is a piece of someones grub config file for debian, that boots it. Then i could just paste it into fedora's grub config.

Ok, Ok, OK, By the looks of it you guys hate me for running fc3, what should i do then, get rid off fc3 and have debian on it's own? I need decent debian guys to awnser this.

Debian 'sarge':s installer would have detected the FC3 installation and created the entries for that if you had installed FC3 first and Debian 'sarge' afterwards.

Anyways, the entry needed in grub's menu.list looks something like this, remember to substitute for what your kernel is there and on what drive it is on:

Code:

title           Debian GNU/Linux, kernel 2.6.8-2-k7
root            (hd0,0)
kernel          /vmlinuz-2.6.8-2-k7 root=/dev/md0 ro
initrd          /initrd.img-2.6.8-2-k7
savedefault
boot

So you need to substitute
- root in grub notation: your is not necessarily on (hd0,0)
- kernel and initrd: your is not necessarily that what is above. the kernel in 'sarge' by default is 2.6.8-1-386 I think.
- root partiton in Linux notation: your is not necessarily /dev/md0 as above. Substitute for something that you have (e.g. perhaps /dev/hda1? I don't know. You need to supply more data)

Essentially I can't say anything more specific without knowing exactly what is installed on what partition and what kernel is Debian using (the exact version of it)

ahaha thanks alot dude you really helped, gonna try it now

its using a 2.4 kernel, that it downloaded, dont ask me why it didnt get 2.6 i dunno

yeah i was gonna do that, installing debian last, but i had no space left on my hd.

Another thing, debian is the first partition (hd 0,0)

You didn't apparetnly specify linux26 at the 'sarge' installation CD's menu. If you just press enter there it will default to use a Linux 2.4 kernel. You need to specify linux26 to get a Linux 2.6 kernel straight away.
Not that much of a big deal, one can always upgrade the kernel after the installation (apt-get install kernel-image-2.6-whatever). But in your case there is the manual messing around with grub when upgrading kernels as the grub you have isn't handled by Debian, but instead it is handled from the Fedora side of things.

why not install grub when running debian and let it take care of FC3....?

That is of course an option, but one should in that case configure the grub management/whatever in FC3 not to update it as it is oh-so-amusing when different OS installations step on eachothers toes regarding the bootloader.

Too Late now, ive already overwritten my previous debian, and deb's grub is taking care of fc3, i'll run synaptic or apt my friend has a kick ass mirror list.
