Get PCLinuxOS 2010 To Boot With GRUB2 Controlling GRUB

[markcynt]

This is a fairly simple process I put together working off this thread ( http://www.pclinuxos.com/forum/index.ph ... #msg585254 ) I started in PCLinuxOS forums.

First of all when installing PCLinuxOS install GRUB to the PCLinuxOS root partition.

Then boot to Mint and run

Code: Select all

sudo update-grub

Then reboot, select the PCLinuxOS GRUB entry and press E

This will bring you to a screen where you can edit the entry.

At the top of the screen you will see an entry like this:

set root='(hd0,13)' (That's what mine was yours may have a different partition number.)

At the bottom of the screen you'll see an entry like this:

initrd (hd0,12)/boot/initrd.img (That's what mine was yours may have a different partition number.)

The two partition numbers have to match so first make sure your NumLock is on and change the bottom partition number so it matches the top partition number.

Then press Ctrl + X to boot into PCLinuxOS

Upon successful boot into PCLinuxOS press Alt + F2, then type kdesu kwrite /boot/grub/menu.lst ( gksu gedit /boot/grub/menu.lst for Gnome ) then Enter and password.

When the file comes up find the PCLinuxOS main entry. For me it was:

Code: Select all

title linux
kernel (hd0,12)/boot/vmlinuz BOOT_IMAGE=linux root=UUID=a60f840a-ac0e-42cf-bc5b-a3f40e138add  resume=UUID=b4d89ce9-0042-4051-a255-47ce8837a276 splash=silent vga=788
initrd (hd0,12)/boot/initrd.img

Again, the partition number needs to be changed like so:

Code: Select all

title linux
kernel (hd0,13)/boot/vmlinuz BOOT_IMAGE=linux root=UUID=a60f840a-ac0e-42cf-bc5b-a3f40e138add  resume=UUID=b4d89ce9-0042-4051-a255-47ce8837a276 splash=silent vga=788
initrd (hd0,13)/boot/initrd.img

Notice that I only changed (hd0,12) in both the kernel and initrd lines to (hd0,13) .

Then reboot back into Mint and run

Code: Select all

sudo update-grub

You should now be able to boot into PCLinuxOS normally.

I know this looks like a lot but it only takes about 10 minutes.

Very nice How-to, markcynt. I wish this was around last year when I was having all sorts of trouble trying to dual boot Mint and PCLOS.

[markcynt]

Thank you. Hopefully it will help a few people.

[exploder]

Thanks markcynt! People have been asking about this and your guide is very much appreciated. Thank you for taking the time to create this.

Yep - I had the edit that initrd bit in this pc.

that was back when direct editing of grub.cfg wasn't in vogue.
but - it worked.

I'd like to thank markcynt for this walkthrough. I was booting four Grub2 OS's and wanted to replace one with Fedora 13. This procedure worked beautifully for me. You're a god!

Thanks for this guide! I used it for dual-booting with Pardus 2011 Beta 2, which uses Grub Legacy (and had taken over my bootloader, leaving my Ubuntu partition unbootable until I reinstalled Grub2).

[sss]

One clarification please, this is necessary because pclinuxos has GRUB Legacy and this disro installed afterwards ( Mint was already installed).

If both distros have the same version (GRUB2) or the distro that is to be installed afterwards has the newer version of GRUB, then still the similar method has to be followed, or we can just overwrite the older GRUB with new version (or equivalent version) of GRUB during the installation of the second distro.

Thank you very much. I followed your directions and they worked like a charm.

Best wishes,
