Hi guys ,
Recently i m using Fedora 8 , but i want to reinstall my system not from Fedora 8 DVD , but Directly from hard disk, and i dont want to use DVD to boot my sytem.

For this purpose i create a ISO image of my Fedora 8 DVD to the destination folder /root/Sulphur.iso
and mount this iso image and copy the vmlinuz and initrd.img file to the destinatin folder /fedora/

after dont this two step i modify my grub.conf file with the following options

title Fedora8 ISO
root (hd0,2)
kernel /fedora/vmlinuz
initrd /fedora/initrd.img


and ther reboot my sytem , and choose the Fedora8 ISO

but it show me the error .

Kernel /fedora/vmlinuz
Error 15:file not found


i dont know what wrong i did with my configuration.

Thanks In Advance

Best Regards

To be fair on us not knowing if you have get everything right it would be useful if you show us the output of

The listing of /boot/grub/menu.lst that is doing the booting would be helpful too.

It is possible that the vmlinuz is just a symbolic link to the kernal in /boot. In any case you need to tell the kernel where to find itself with the parameter "root=/dev/sda3" and the read-only parameter "ro" in the kernel statement.

The root (/) partition is my lvm partition .
here is the output of fdisk -l

And this is my grub.conf file

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

Go into command mode, type 'kernel /', then hit tab.
Grub will show you what what he sees on that root device.

kernel command is not found in my system
any subsitute of this command

If you want Grub to assist you then put a # in front of these two statements temporary and lengthen the time you can play with the Grub screen (marked red below).
When you see the screen press "c" key to drop into a Grub Prompt.

You then tell Grub the root partition and type part of the kernel name like this
do not press return but hit the tab key. This causes to go inside /fedora directory to find all files that matches "vmlin". You will be given a list of files. You then type the rest of the file name.

You can do the same for the initrd statement.

Type this line to give green light to fire up the Linux
But like I said you need to tell the kernel where to find the root. Grub only load the kernel and the "root=" parameter must be present otherwise the kernel will not find the system files. You existing Fedora boots to "FirstVolGroup00/FirstLogVol00" which is the LVM in /dev/sda9.

You are not listening.

• Boot grub
• Hit esc to get into grub console mode
• enter 'c' for command mode
• type 'root (hd0,2)'
• type 'kernel ('
• hit tab and a list of what grub sees will be returned.
• now chose what you want, using the tab key to complete names
• repeat for initrd
• enter 'b' to boot with these parms

It is my 'lab notes' on using Grub that I put up to help others. If I don't write things down, I forget them. Very popular, many hits a per day.

I have done what you are trying to do with FC8 and FC10. It works well. Good luck.
