Adding Mandrake 10.0 Community to Red Hat Grub boot loader
 

Hey guys I jsut recently got into Linux (I knwo what took me so long)

I have Windows 2003, RedHat 8.0 and Mandrake 10.0 Community all installed on my puter and they were installed in that order.

I can boot Win2k3 and RedHat but not Mandrake. I knwo I got to edit the Grub config but I don't know the paramaters to put or anythign like that. I can figure out what partition my mandrake is on but I don't know what to exactly put into the config file. I reade something about the kernel version and what not but I can not find that page again. I looked at it when I was thinking aobut trying different distros. ANy help would greaty be appreciiated after I get this working I plan on installing SuSE 9.0 as well so that I will have Windos 2003, RedHat, Mandrake and SuSE

I would have RedHat 9 or Fedora but don't feel like downloading it right now lol

Any help will greatly be appreiciated and I will be constatly checking the forums in the next few hours to see if any solutions. Thank you for any help in advanced

Here is my drive setup incase it helps lol

and here is wht is in my grub.conf

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd1,0)

#boot=/dev/hda

WOW all these relpies and not one smidge of help comeon guys please lol ?

okay what kernel version is mandrake 10

THese are the only lines that I need help with so if someone that has mdk 10 could go into their boot folder and tell me what the number sequence is for the vmlinuz and initrd that should be all I need then thank you

kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdd=ide-scsi
initrd /initrd-2.4.18-14.img

I assume your boot loader is installed from the RedHat 8.0 system.

If that is the case, you need to add a record to /etc/grub.conf for the Mandrake 10.0 system.

You can find what to add by mounting the Mandrake partition in RedHat 8.0 and then
loading /boot/grub/menu.lst from that partition into an editor and copying the record that looks like

title linux-enterprise
kernel (hd0,9)/boot/vmlinuz-enterprise root=/dev/hde10 noapic devfs=mount acpi=ht resume=/dev/hde9 splash=silent
initrd (hd0,9)/boot/initrd-enterprise.img

to the end of your RedHat 8.0 grub.conf file. Your hdx.y and hd parameters will be different than mine.

Then boot and choose that line to boot into Mandrake 10.0. You can change the "linux-enterprise" title to anything you want, such as "Mandrake 10.0" for example.

Hope this is what you need.

oooookkkaayyy lol well thank you for your input lol but I am noobtacular with linux I have only had gotten into it like 3 days lol how do I mount a partition? Now with that question you know that I am a total noob lol

I think I have tried to mount liek my windows partitions but nothing was there and the only thing I saw was my cdrom

okay in terminal I think this is how your supposed to mount anyways this is what I got

[root@localhost root]# mount /dev/hdc5
mount: can't find /dev/hdc5 in /etc/fstab or /etc/mtab
[root@localhost root]#

Ok, try this

At the root prompt,

mkdir /mnt/mandrake

This creates a mount point for the partition.

Now,

mount -t ext3 /dev/hdc5 /mnt/mandrake

It should now be mounted.

Then,

kate /mnt/mandrake/boot/grub/menu.lst &

should open the mandrake grub configuration file in kate for you copy the record from.

kate /etc/grub.conf &

should open the editor for your RedHat 8.0 grub.conf file so you can paste the record there.

Okay well I did what you posted and I was able to mount my mandrake, but there was no grub.conf there. That might be because I read that when you install another linux when you ahve one already on your system to not install the boot loader from the second linux so I didn't install a boot loader with Mandrake.

I got it to kinda start up but this is what I got

ext3-fs: unable to read superblock
mount: error 22 mounting ext3
pivot root: pivot_root (.sysroot, /sysroot/initrd) failed 2
Remounting devfs at correct place if necessary
mounted devfs on /dev
Freeing unused kernel memory: 272 freed
Kernel Panic: No init found. Try passing init=option to kernel

what is wrong? or what do I have to change?

I'm sorry I didn't make myself clear.

You need to make the changes to the *RedHat* /etc/grub.conf file.

The information you need to add to the end of the RedHat /etc/grub.conf is the information for the linux-enterprise entry in your Mandrake /boot/grub/menu.lst file.

That information should look *similar to*

title linux-enterprise
kernel (hd0,9)/boot/vmlinuz-enterprise root=/dev/hde10 noapic devfs=mount acpi=ht resume=/dev/hde9 splash=silent
initrd (hd0,9)/boot/initrd-enterprise.img

that I posted from my Mandrake /boot/grub/menu.lst file earlier.
