Second Hard Drive?

Frank Soranno · 05-19-2006, 06:02 PM

I have Fedora 5 on my master 80 gig HD, with the latest kernel 2.6.16-1.2111_FC5.
Just installed a second 20 gig WD hard drive with win xp as slave, Went to bios and it was recognized as slave, Then booted up, went to /fdisk and it was recognized ok, Now how do I get into it to use? My /boot grub dosen't show it either. What's the next step?

Try adding this to your /boot/grub/grub.conf:

Code:

title Windaz
        rootnoverify (hd1,0)
        chainloader +1

where hd1,0 is the first partition on your primary slave (/dev/hdb)

On reboot it appeared in grub, but didn't launch? What next?

Yo! Dudes! windoze is on the second (slave) drive. It doesn't like that; it wants to be first (master) of the situation. You need to re-map the drives to fool windoze into thinking it's on the first drive.

Like so:
title Windaz
map (hd0,0) (hd1,0)
map (hd1,0) (hd0,0)
makeactive
chainloader +1

You may need to add the rootnoverify line in there after the map commands. And, you may need to say 'rootnoverify (hd0,0) instead of (hd1,0).

Thanks bigrig!

OK Guys, Now I'm getting "NTLDR MISSING" after I choose Windows,I'm not sure if I have XP loaded on the slave,Check this out,

First thing I'd check: Is the partition containing Windows set to Active?

JW, I just switched over and installed Ubunto as the second HD slave.Same problem, Can't mount second HD (slave).On Grub boot I have fedora 5 which will boot if I select it and Ubunto after I select to boot Ubunto I get this "Error 13 Invalid or unsupported executionable format" Do I need to add to etc/fstab and /etc/mtab? I don't know what to add and how to do it, Need help. Thanks

Let's recap your HD layout, as I'm no longer clear on which OS is on which drive. As a general comment, Windows expects to be on the primary master (/dev/hda) but if you install it on the primary slave (/dev/hdb), you will need to modify GRUB as bigrigdriver explained.

Assuming you can boot Ubuntu (or if you have a Live CD such as Knoppix), open up a terminal session and run the following command

Code:

cfdisk /dev/hda

That will display how /dev/hda is partitioned, along with the file system type of each partition. Write down the info that is displayed, quit the command (don't make any changes), then run

Code:

cfdisk /dev/hdb

Post the results of both commands, so we can see what you're seeing. Also, please post your current /etc/fstab

Bottom line is that the Windows prefers to be on the primary master, and must be in a partition that is bootable. (You can adjust the bootable flag via cfdisk) Linux doesn't care where it lives, so typically it's easiest to just put the drive containing Windows into the primary master position (make sure it's jumpered correctly) and the drive containing Linux into the slave position (again, make sure it's jumpered correctly) and use the standard GRUB or lilo boot loader settings

JW, I can't get this thing resolved, I tried a live Cd and gave cfdisk /dev/hda and cfdisk /dev/hdb and in both I got fatal error and black screen.Here is /etc/fstab
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0

sysfs /sys sysfs defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0

Hi, not sure why cfdisk didn't work... Ubuntu is Linux and uses the same layout as Fedora, you should try to copy Ubuntu's entry in /boot/grub/menu.lst. Here are the two fedora entrys:

Code:

title Fedora Core (2.6.16-1.2111_FC5)
root (hd0,0)
kernel /vmlinuz-2.6.16-1.2111_FC5 ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.16-1.2111_FC5.img

and:

Code:

title Fedora Core (2.6.15-1.2054_FC5)
root (hd0,0)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.15-1.2054_FC5.img

Ubuntus' is wrong, this is what it should look like:

Code:

title Ubuntu
root (hd0,1)
kernel /boot/[vmlinuz]
initrd /boot/[initrd]

Replace [vmlinuz] and [initrd] with the name of the kernel image you see in /mnt/hdb1/boot/, or even better, copy the entry you see for Ubuntu in /mnt/hdb1/boot/grub/menu.lst (if it exists).

Let me know if this is making sense to you

The complicating factor here is that it's just plain unclear what you've got installed, and where it is installed. At this point, I'd suggest just forgetting about trying to finesse it, and to instead just force it to work. This is what I'd suggest:

1. Physically remove whichever drive contains Linux.
2. Put the drive that contains Windows in the primary master position. Make sure it is jumpered to be the master.
3. Reset the Master Boot Record (MBR) of the primary master. Do this if you have Win 98 or this if you have XP
4. At this point, your only boot option (and only disk drive) will be Windows. No problem, Linux hasn't gone anywhere
5. Put the drive containing Linux into the slave position. Make sure it is jumpered to be the slave.
6. Using your Linux installation CD or a Live CD, boot into Linux, and restore the boot manager

Overall, due to Windows not playing nice, it's just way easier to install Windows first, let it have the first partition of the primary master, then install Linux

Hi JW, I did that exactly as I described above, Not sure if I made it clear, But 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 project. Frank

Hi all

A little suggestion. Can i know the model no of ur mother board. In some of the motherboards there is a extra option is added at boot time which gives u the choice to boot from different physical hard disk.

I am using two Hdd and the win xp is on second hard disk . On my motherboard (intel 845) it gives a choice to select boot from boot menu by pressing F11 key, it displays all the drives as hd0 hd1 etc i just have to select the drive and all is set. Win xp runs smoothly.

Just gussing that may be u have some kind of board like mine. Try looking at startup options.

Regards
