I got a new laptop (dv9000) and it came with Windows Vista. I just set that a side and installed PCLinuxOS 2007 and it installed it's own boot loader... everything went well I could use both Operating Systems.

Then I installed Fedora 7, it too install it's own boot loader (Grub)... BUT I can only access Windows Vista and Fedora 7... NOT PCLinuxOX 2007

How can I make PCLinux 2007 work with the Grub boot loader???

sda = hard drive
sda1 = vista
sda2 = boot loader
sda3 = extended
inside sda3 is sda5 = Fedora 7
inside sda3 is sda6 = Linux swap (which I don't think works)
inside sda3 is sda7 = /home
inside sda3 is sda8 = PCLinuxOS 2007
sda4 = HP Recovery

under: System > Administration > Bootloader I can pick between OS, but can't change them. It does list Fedora 7, PCLinuxOS 2007, and Windows Vista.

When I try to load PCLOS it does give me an error... I'll go see what it is, brb.
back... error is:

booting 'PCLinuxOS 2007'
rootnoverity (hd0,7)
chainloader +1
Error 13 Invalid or unsupported executable format

I opened /boot/grub/menu.lst

title Fedora (2.6.21-1.3228.fc7)
root (hd0,4)
kernel /boot/vmlinuz-2.6.21-1.3228.fc7 ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.21-1.3228.fc7.img
title Fedora (2.6.21-1.3194.fc7)
root (hd0,4)
kernel /boot/vmlinuz-2.6.21-1.3194.fc7 ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.21-1.3194.fc7.img
title PCLinuxOS 2007
rootnoverify (hd0,7)
chainloader +1
title Windows Vista
rootnoverify (hd0,0)
chainloader +1

that makes it look like PCLinuxOS is setup like Vista... which isn't right. So I replace it with something?

Yes you need to change your PC Linux entry. The best way I have found is to open your /boot/grub/menu.lst in (sd8) and copy the top entry and then paste it in the /boot/grub/menu.lst of (sd5). Remove your entry for chainloading PC Linux.

root (hd0,4)
kernel /boot/vmlinuz-2.6.21-1.3228.fc7 ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.21-1.3228.fc7.img

what should I put for the Kernal and initrd??? because that has fc7 in it!

I tried the following and got an "Error 15"

title PCLinuxOS 2007
root (hd0,7)
kernel (hd0,7)/boot/vmlinuz-2.6.12-oci4.mdk root=/dev/hda3 vga=0x317
initrd (hd0,7)/boot/initrd-2.6.12-oci4.mdk.img

That doesn't match your other entry
What partition is pclinux on?

What is the output from: fdisk -l

If the top thread is correct root should be at sda8. cole07 give us a "fdisk -ls"

The most elegant way to do it is stick with the menu.lst in Post #1.

Your PCLinuxOS will boot if you are activate a Grub shell or Grub prompt and issue these commands
Remember you can only chainload a Linux if you have installed a boot loader in its root partition. You have only been putting Grub in the MBR for both Fedora and PCLinuxOS. The "root" + "setup" statements above put it right for you.

As a minor refinement in Linux no need to use "rootnoverify" which is for a partition without a kernel. "root" is adequate for every Linux but the use of "rootnoverify" does not affect the booting materially.

umm... I can't fdisk -l or fdisk -ls
here is the terminal:

[dcole@localhost ~]$ su
Password:
[root@localhost dcole]# fdisk -l
bash: fdisk: command not found
[root@localhost dcole]# fdisk -ls
bash: fdisk: command not found
[root@localhost dcole]#


what am I doing wrong here?
--- ----
rootnoverify was the default thing after I installed PCLinuxOS... No input on my part.

Don't forget to use the dash ( - ) like this...

Here you go:

so basically, what should the whole PCLinuxOS look like in menu.lst? I'm dumber than I appear!

If you have a SATA ( sda ) drive, it will probably look like this...
and thanks to a curve ball from FC7 , grub entries for other linuxes which are on an
IDE drive ( hda ) would look like this...

If you insert the lines, as suggested in Post #11 into the Fedora's menu.lst or grub.conf that constitutes direct method of booting and you need to be precise with the kernel and initrd names.

The suggestion in post #7 is indirect method of booting requiring nothing except the partition number with PCLinuxOS's /boot.

Both methods works perfectly.

Both methods works perfectly. You can have them both because they can co-exist together.

You can fire up PCLinux in Fedora's Grub right now by pressing the "c" key to drop into a Grub prompt with command
The above put Grub inside root partition of PCLInuxOS and then boot it up.

Alternative you can fire up PCLinuxOS without restoring Grub just by this command
There are so many ways to skin this cat.
