Hi all !
The problem :
1 - First I have a fat32 partition for WinXP .
2 - I install System commander 7 on the MBR. All works
3 - I install Fedora core 3. I choose manual partitionning with Disk druid :
I create a ext3 mounted as / (7Go )
and swap partition
4 - So my disk have this face :
hda0 : ext3
hda1 : swap
hda2 : fat32

5 - I choose Grub bootloader and I install it on the first sector of boot partition.
6 - I finish the installation.
7 - Reboot : System Commander comes up and recognized Linux and Windows
8 - I choose Linux : it boot normally
9 - I choose Windows : error : it said that a .dll file is missing and cannot boot x_x : (It happened already on 2 pc that I install like that. )

So, for some problems, I decided to format ALL my disk => clean !
Then I install Fedora 3 with a disposition of partition like before.
After that I install WinXP then System Commander. it recognized the 2 OS.
Windows boot normally but now Fedora have problem (arghhhh x_x) : I have grub command prompt :
GNU GRUB version 0.95 ......
[ Minimal BASH-like line .....

grub >

So what can I do ????????
I don't want to reinstall again !!!!!!!! And also, how can I install Fedora 3 on a disk that already have XP without re-installing ALL ????

(sorry for my english)

The problem is that the tutorial doesn't resolve how I can boot Fedora normally without to reinstall ALL again ....

You might want to try it this way. The difference would be your using one hard drive. Make a partition for Fedora. Then follow the instructions.





My Fedora Core 3 Install

This by all means may not work for everybody and I can't explain why it happened I can just
guess. I've been working with Red Hat since version 6.2. My company is going to change all our
operating systems mid next year to Red Hat Enterprise Edition. The reason why I like Fedora is it's
always a challenge to make it work when your running on the cutting edge of hardware.
I want to thank all the people and their suggestions on this forum.

I run an Intel D865perl motherboard with 2.6 gig Intel processor with 1 gig of ram. Two 160 gig
hard drives. The first hard drive is for Windows XP. Second hard drive is for Fedora and data
backups.

Drive 2 the first 40 gig is Fedora and the second 120 gig is for files backups and Norton ghost 2003
images. Which I never doing anything without a current image file it will save your butt.

Install Fedora Core 3 on the second hard drive and use the automatic partitioning tool but don't
put grub on your Master MBR put it on the first sector on your second drive. When you get to the
Boot Loader Configuration screen make sure you check the Configure advanced boot loader
options. The next screen will give the option where to put Grub Boot Loader. It should say like
hda or hdb. Hda is usually your XP Drive. From their finish loading. Put it on hdb.

Now duel booting using XP boot manager (My Preference. I don't like third party boot managers.)

Use your rescue CD to boot to Fedora.
Hit enter at the boot prompt.
Hit enter for English
Hit enter for us
Setup network select no
At the rescue screen select continue
At the next rescue screen hit enter
Now you have a prompt sh-3.00#
At the prompt type in chroot /mnt/sysimage
If hdb2 is Not your boot partition, change it as appropriate. Type: df then determine which hda#
Run the command dd if=/dev/hdb2 of=boot.lnx bs=512 count=1
You should see
1+0 records in
1+0 records out
Type ls and you should see a file named boot.lnx
Put a blank floppy disk in your a: drive
Type mcopy boot.lnx a:
It should have copied the file to your a: drive

Now reboot to Windows

Copy boot.lnx to your root directory
Right click on your boot.ini file select properties and uncheck read only click ok
Double click your boot.ini file and add one line at the end it should read
C:\boot.lnx="Fedora Core 3". Then save it. When you reboot your XP boot
manager will come up and you can chose Fedora it jumps to the Grub Boot manager on your
second drive.

My file looks like this

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(0)(1)\windows
[operating systems]
multi(0)disk(0)rdisk(0)partition(0)(1)\windows="Microsoft Windows XP Pro SP2"
/fastdetect /NoExecute=OptIn
c:\boot.lnx="RedHat Fedora Core 3 Project"

You call it anything you want

Oki !
