<solved> added a 5th OS and now having boot issues

Hi Nish,

He is installing debian via virtualbox to a file rather than to a partition. If it goes wrong or he gets bored he deletes the file, no effect to the real grub or real system. Safer way to play....

This thread is boggling my head, learning new things,

Have fun,

I am having to install mature 64bit distros in order to test a hardware problem.  To be specific, an unlocked core on my cpu.  I am not sure I could trust test results in a VM. 

After a little debacle with another 64bi that had grub2 thought I had the disastrous installs licked as long as I only let their grubs go to partition and chainloaded from my mbr grub.  Guess not.

Hi Phil - me and deb are old friends. I was running sid from ten years ago and installed more times than I can remember like even before there was a graphical installer.  Though there is a soft spot in my heart for the ncurses dialogues  

Not sure what happened here, grub2 - only thing I can think of is the device map. Checked current map in the grub on my poor ruined PCLOS and it is correct. Why has it gotten into its head that is sda?  And even the PCLOS 2011 liveCD thinks it is sda?  that is scary

I will have to wipe it in a few hours. Need to get back to business and I can't be messing about with this testing distro, need my stable OS back. 

Still would love to know what happened.

With only two hard drives, the boot drive is always (hd0) and the other (hd1). You have three hard drives present. The boot drive is still always seen as (hd0) but the others, in no set order, will be (hd1) and (hd2). Therein lies your problem, and the reason I use a boot partition on each of my drives.

If you copy the boot stanza shown earlier, and paste it immediately below the original, then edit the copy as shown, I think you'll find it will work.

title PCLinuxOS (hd2)
kernel (hd2,1)/boot/vmlinuz BOOT_IMAGE=linux root=LABEL=Linux resume=LABEL=swap2 splash=verbose vga=788
initrd (hd2,1)/boot/initrd.img

Just did it, and no, it doesn't work.  New message - error 17  cannot mount selected partition

If there is anything else you want to try before I grab the seagate disk and write zeros to this cursed thing let me know.

Open a terminal, su to root, and issue these commands;

[root@localhost ~]# mkdir -p /mnt/here                   <Enter>

I'm trying to figure out what's happening with your boot menu options.

You show a correct kernel and initrd image pair, the links are proper, the UUIDs in the original boot stanza seem correct, the LABEL in the (hd2) stanza works, so the only substantial difference is that one looks for the kernel on (hd1,1) and the other looks for it on (hd2,1). One or the other should work, unless you told me a fib, and your grub is actually installed on the MBR of the same drive, in which case you'd need to look for the kernel on (hd0,1)

Copy the stanza with the LABELs and edit to read;

title PCLinuxOS (hd0)
kernel (hd0,1)/boot/vmlinuz BOOT_IMAGE=linux root=LABEL=Linux resume=LABEL=swap2 splash=verbose vga=788
initrd (hd0,1)/boot/initrd.img

Reboot and use that stanza.

Unless you're hiding a fourth drive somewhere on that machine, one of those three stanzas has to work.

[Nish]

There is no fourth drive anywhere to be found.  I have two hard disks.  And an external drive via USB.  That's it.  I still don't believe that the few times I booted a PCLOS 2011 live CD it was showing the two installed hard disks flipflopped but it did.  BBL

OK, it worked.  I am here.  


taking that back the hd0,1 does not work but the entry above it did (hd1,1 - but did we not try that?).  Have to try this out a few more times.

Yes, I can confirm the hd1,1 works.  Which is what I did originally, no?    This is what is working

title PCLinuxOS (hd1)
kernel (hd1,1)/boot/vmlinuz BOOT_IMAGE=linux root=LABEL=Linux resume=LABEL=swap2 splash=verbose vga=788
initrd (hd1,1)/boot/initrd.img

OK, it worked.  I am here. 

So now, what to do to put grub right from here?   Rather than from the other install?  I can just make it the default from there I suppose but that would be too easy 

You can choose any hard drive to be the boot drive. You need to decide which OS should be the one with the master grub, then install grub to the MBR of the same drive it resides on and set that drive as the boot drive in BIOS. Your boot stanza in the master menu.lst should then point to (hd0,n) with n being the partition number, counting from 0.

When you install any additional OS, install that installation's grub to the PBS (Partition Boot Sector) of its / partition, then either copy the first boot stanza from its menu.lst to the master menu.lst of the original installation. Alternately, you can just write a chainload stanza for the new installation in the master menu.lst If the new installation is on a different drive, the stanza you write or copy must be written or edited to look for the kernel and initrd image on (hd1.n). If you install grub to a partition, during the initial installation, you will be asked which drive you actually boot from, and if you give the correct answer, this will already be taken care of.

You can use the grub native install method to choose which installations grub will be the master grub. You can do this from the installed system or a liveCD. The instructions are the same for either.

Rather than mess with anything when it is working, I am just making this option the default from the other grub.  I just can't take any more excitement, rilly.  This works.  That's ok by me    If I try and make a new menu.lst here that works I am liable to screw something up. 

thanks
