Second Hard Drive?

fvs

I removed Win XP and installed Ubunto on the 20gig (slave) while I had the (master) disconnected.Put the (master) back and tried to boot, I stiil can't get the (slave) to boot. I'm just trying to boot from either hard drive, Which I have installed, Seagate 80 gig (master) which has Fedora 5 and WD 20 gig (slave) which has Ubunto only no win XP at all. All I want is to be able to switch drives from the boot. I really don't care about Win XP.I hope this helps clears up my delema.
Thanks for helping me with straighten out my projects. fvs

I'm using grub. I have fedora (Master) on first drive, Ubunto (Slave) on second drive
both have grub. No other Operating systems.

easy, two linux installs, grub can present you with a menu on bootup, you choose which flavor you want to boot.

grub> kernel /vmlinuz root=/dev/hda1

grub> kernel /vmlinuz root=/dev/hdb1

just change the name of kernels and devices and you're done. this is why bootloaders such as grub or lilo or any other bootloader exists.

check out the documentation here
http://www.gnu.org/software/grub/manual/grub.html

and linux specifically here:

Hi lighnin, I've tried all the sugestions and when I boot to the second drive I get a kernel panic and have to shut down and go back to Master, what am I doing wrong?

I would advise only using one bootloader. On your master drive, add the boot entries from the bootloader on your slave drive. For example:

Master:

timeout=5
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title Fedora Core (2.6.16-1.2122_FC5)
root (hd0,1)
kernel /vmlinuz-2.6.16-1.2122_FC5 ro root=/dev/VolGroup01/LogVol00 rhgb quiet
initrd /initrd-2.6.16-1.2122_FC5.img
title Fedora Core (2.6.15-1.2054_FC5)
root (hd0,1)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup01/LogVol00 rhgb quiet
initrd /initrd-2.6.15-1.2054_FC5.img
title Other
rootnoverify (hd0,0)
chainloader +1
title second
root (hd1,0)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup01/LogVol00
initrd /initrd-2.6.15-1.2054_FC5.img

Slave:

timeout 30
title Ubuntu Linux ver. Greasy Grouse
root(hd0,0)
kernel /vmlinuz-2.8.12 root=/dev/hda3 video=vesafb:mtrr:1024x768-32@60

Becomes:
timeout=5
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title Fedora Core (2.6.16-1.2122_FC5)
root (hd0,1)
kernel /vmlinuz-2.6.16-1.2122_FC5 ro root=/dev/VolGroup01/LogVol00 rhgb quiet
initrd /initrd-2.6.16-1.2122_FC5.img
title Fedora Core (2.6.15-1.2054_FC5)
root (hd0,1)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup01/LogVol00 rhgb quiet
initrd /initrd-2.6.15-1.2054_FC5.img
title Other
rootnoverify (hd0,0)
chainloader +1
title second
root (hd1,0)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup01/LogVol00
initrd /initrd-2.6.15-1.2054_FC5.img
title Ubuntu Linux ver. Greasy Grouse
root(hd1,0)
kernel /vmlinuz-2.8.12 root=/dev/hdb3 video=vesafb:mtrr:1024x768-32@60

Note that since the slave drive is second in the chain it becomes hd1 and hdb.
