Dual boot HD recognition problem

[karlsson]

Hi!
I have Fedora7 installed on sda.
I installed Mandriva2008 on sdb.
On boot you could only see mandriva.
Xbootloader reacted by exiting when I tried to add fedora and you can't access it now.
i've added fedora in /boot/grub/menu.lst but the path is not recognized for some reason.
do you know anything about it?
please, help!

Hello.

Your external HDD will be reconized, as if it where a USB stick.

Proceed in this way:

1.) Unplug your external device/disk from the USB port of your computer.

2.) Start up your computer.

3.) After start up, when you can see your desktop window, plug in your exteranl HDD.

4.) You will then see a USB-stick icon on your desktop.

Now you see, that your HDD was recognised/detected.

Edit.
P.S.:
This looks like the HDD your are looking for. Anyway, it will be named as ".../media/..., because it is plugged into the USB-media port:

/dev/sda1 /media/hd ext3 sync,relatime 0 0
/dev/sda2 /media/hd2 auto umask=0022,users,iocharset=utf8,sync,noauto,flush, exec 0 0

It is actually only one disk, but your system can only show it as two devices, and as two "USB-stick-icons" on your desktop.

Anyway, it is something like that...

Edit.
P.S..

- Oh, and another thing:

I just saw, that the external disk looks like it is quasi "the master", and the other one "the slave".

Well: The disk with Windows on it, will only boot, if it is inside of your computer. Internal.

And you will have to set it at first position within the booting sequences in your BIOS.

Well, now you might be able to figure out, what might be going wrong with your dual boot system.

Edit.

P.S.: Silly me: I had another look at your post: So much information... I just see now, that you do not have windows.

Well, that should make it a little easier. A dual Linux dual boot: Ok, nice...



Cheers,
Alexander

thank you!
But I have 2 hard drives, both internal

somehow mandriva is now associated with /dev/VolGroup00 instead of Fedora. This is probably because of me messing up XBootLoader, which can't be accessed now.
So if mdv overwrote Fedora's boot directory. is there any way to get to all the data on Fedora???
please, help me!

When in Mandriva, execute these commands as root.
mkdir /mnt/fedora
mount /dev/sda1 /mnt/fedora

Bring up your "file manager-super-user" and browse to the directory you wish to see.

Note: it doesn't have to be /mnt/fedora, it can be /fedora if you want, I just personally like those directories to be in /mnt.
And if sda1 is not correct, adjust accordingly.

thanks!
I can only mount sda1, where there is kernel etc.

but when i try to mount sda2, i get:

[root@localhost grub]# mount /dev/sda2 /mnt/moujik
mount: you must specify the filesystem type
[root@localhost grub]# mount -t ext3 /dev/sda2 /mnt/moujik
mount: /dev/sda2 already mounted or /mnt/moujik busy

I'm gonna try to change grub.conf cause so far I get error 17, due to faulty VolGroup00
any suggestions?
