Problems when adding a second Linux OS (On a 2nd HDD)

[David_J_D]

Apologies to mods if this appears to duplicate mrwaistcoat's thread, he felt I was trying to hijack his thread. I wasn't.

I'm having problems doing just this. Briefly:

1st HDD has Win7 & PCLOS living happily together, using the whole disk, but doesn't see Mint.

2nd Hard Drive has Linux Mint Debian, when this is 1st boot device, Mint is fine, sees Windows OK but doesn't see PCLOS.

I've been editing PCLOS's grub menu.lst (I backed it up first), by adding the following lines:

title Linux Mint Debian
kernel (hd0,4)/media/disk/boot/vmlinuz-3.0.0-1-686-pae BOOT_IMAGE=Linux_Mint_Debian root=UUID=d7374e6d-93c4-4d31-bd4f-7256e351a690
initrd (hd0,4)/I'm having problems doing just this. Briefly:

initrd (hd0,4)/boot/initrd.img

I have installed Mint's pae kernel and it boots it correctly when it's the first boot device.

and changed the (hd0,4) to (hd1,4), (hd1,0), (hd1,1) in both lines where it occurs.

What's the magic incantation to get Mint booting from the PCLOS Grub menu?

Or would I be better off editing Mint's grub menu and booting from the other HDD?boot/initrd.img

Why did you make those specific changes?
Do you know what they do?

FYI ...  the first number refer to the HDD and the second to the partition on which the OS you wish to boot is installed.
Both numbering systems start from zero.

So if you have two HDDs, the first one - the booting HDD - will be (hd0 ...... 

I have no idea what your partition layout is like so cannot suggest any number for that.


You may find it easier to use the following to boot the Mint HDD

title 2nd HDD
rootnoverify (hd1)
chainloader +1

I am not certain that will work ....  but think it should
