Hi, I'v read many Threads about similar problems but couldn't fix mine though.

I have one hard drive, 80G, partitioned into 7 parts as followed: (from pm8)

I Installed WinXp on Drive I (NTFS) and then install RH9.
I followed the instructions on this link in order to dual boot those Os's:

Now I have the option to choose winXp or RH9. When I choose WinXp everything works fine.
When I choose Linux RH9 I get the following error:
<Windows root> \system32\hal.dll
My boot.ini file :

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Pro" /fastdetect
I:\linux.bin="Linux RH9"
My "grub.conf" file is configured as followed (Only the WinXp part):

title WinXp
     rootnoverify (hd0,0)
     chainloader +1

I didn't write here the fdisk partition for u to see but I tried all numbers instead of the "zero" in (hd0,0) although I know winXp is No.1 . (Thus supposed to be 0 in Grub).
If it's important I can write that too.
pls pls help because I'm very frustrated and tired from this RH installation :)

I don't know grub. But what's happening here is that your RedHat boot does not boot RedHat.

You should boot your rescue disk, check your grub config and re-apply it to your boot sector.

What's in your grub.conf (or menu.lst) file for your Linux partition?

Do you have a boot floppy for your Linux system?
You can always use Grub in the MBR to boot both your operating systems. If this fails, you can restore your MBR using the fixmbr function from your WinXP install CD.

yes I have a bot disk for linux.  Here is my grub.conf:
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file

#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,1)
#          kernel /vmlinuz-version ro root=/dev/hda6
#          initrd /initrd-version.img

If I have to use GRUB for Both Os's (as u said) please tell me  how to do this. Of course, if u can tell me how to fix my current configuration it's better for me.

Alf666 - What should I check in Grub.conf and how do I re-apply it to my boot sector.
thanks a lot,

To re-install Grub run this command (as root):
grub-install /dev/hdaX
- with hdX replaced by your actual boot device.

If I interpret the PM output correctly (and I don't have a lot of experience with this), the correct command line for grub-install should be:
grub-install /dev/hda2

(and this seems to be also what the RH installer used when it wrote the menu.lst file)

I would boot the Linux system with the boot floppy and follow the instructions on the web page that you quoted again. The instructions look correct, it's possible that you made one small mistake (e.g. copied the wrong boot sector). Make sure that you check and double-check all device names that you use. Don't use the ones from the example, always use the correct names for your system.

I suspect that grub has not been installed at all on the boot sector.

When you boot, do you get grub or the standard windows boot selector menu ? (I suspect windows).

In this case, do as khkremer says.

Ok, it works (partially)
I changed the boot .ini to call linux.bin from c:\
At first I wrote  I:\linux.bin="Linux RH9" (As I wrote before) because 'I' is my WinXp drive so I thought it should be he same.
Anyway, I'm getting to grub but I get all the options that are written in my grub.conf file (above).
What option should I choose to enter my red hat 9 installation? Why do I have all this options and how can I delete the one's I don't need.(and what are the one's I can delete).
Can I only delete them from the grub.conf file or are there additional components that should be removed?
Btw - it's a RH9 updated from RH8.

thank u very much,
LVL 44

Select the first one. You can delete the others. When RedHat adds a new kernel (or a new configuration), it will add an entry to the Grub file. This way you may end up with lots of entries that you don't need anymore. Once you know that your default configuration is working, you can edit the grub.conf (or menu.lst) file and remove the ones you don't need. Just keep the first one. You don't have to do anything else but to delete the records from the file.
