What's the command for bringing up..

[buccaneere]

... the location of other OS's on other hard disks that I've added to my desktop box?

I plugged in two other HD's to my desktop - one with XP, and another with PCLinuxOS, and I want to import those respective grub loaders from those 2 disks into the Ubuntu Grub loader.

The XP disk is already dual boot w/an older ubuntu version; what difference does that make?




Thanks...

sudo fdisk -lu
will give you the location of other drives/partitions/OS's
gksudo /boot/gru/menu.lst
will let incorporate the rest of the OS's

On it......

[buccaneere]

I've done something wrong... The additions appear in the grub menu, but will not load. They will load if the IDE cable is switched directly to the respective disks.

Help?

Sounds like you have the


root (hdx,x)

line messed up somehow.

Grub names disks and partitions starting at zero, meaning that sda1 would be (hd0,0) while sda2 would be (hd0,1) etc. If you have more than one disk, it could look something like (hd1,0). That is the first partition on the second disk.

Make sure the entries for your different operating systems point to the disk/partition they are actually installed to.

Sounds great skones!

Now... What's the command for bringing up ... the location of other OS's on other hard disks that I've added to my desktop box?

Specifically - the boot loader/partition for those other OS's? Does that value show as a return for the command that puma gave me?




Wow - we just did a do loop!

[SkonesMickLoud]

Does that value show as a return for the command that puma gave me?

Yes, but it takes a little bit of decoding.

Can you post the output of:


sudo fdisk -l

(that's a lowercase 'L' by the by)

and:


cat /etc/fstab

Thanks again there puma..

What am I changin' there? If it doesn't work, will I be able to revert without a meltdown?

I like knowin' what I'm doin' before I do it - that way I might learn a fix to apply to other processes, AND, help others at the same time...

[Pumalite]

You are changing fstab to correspond with menu.lst, fdisk and blkid
The kernel checks fstab at boot. If it doesnt work; you can change it back.

[buccaneere]

Well, something changed...

After GRUB, XP is 'starting up'. And that's as far as that goes. PCLinuxOS option returns 'invalid executable file (or something of the like)'; press any key to continue'.

Any other ideas what I've got wrong?

Get Super Grub and see if it can boot your OS's:

Burn to disk and boot from it.
