When I have first time rebooted Fedora 5(during the installation process) error 15 occur and the system did't load(any system because i'have also Windows XP on another physical disk).And I don't know what it means?

Grub error 15
After hitting return in the grub prompt you get something similar to this one?

Code:

Booting 'gentoo Linux'



root (hd0,0)

Filesystem type is ext2fs, partition type 0x83

kernel (hd0,0)/boot/kernel-2.4.20 root=/dev/hda3 vga=792



Error 15: File not found

Press any key to continue...

15 : File not found

This error is returned if the specified file name cannot be found, but everything else (like the disk/partition info) is OK.

If it's the kernel that it's missing (bzImage, kernel...):make sure that the file it is referring to exists on your boot partition.

To find out what the exact name of your kernel is, first boot from the live-cd or into your existing linux installation. Then mount /boot if you've got a seperate partition, or mount / if you don't. Then do the following:

Code:

cd /boot

ls

This will list all the kernels that you've got on your boot partition.

If your kernel is missing make sure that you compiled a kernel either with genkernel or make menuconfig

Code:

 cd /usr/src/linux/

make menuconfig

and you copied it to your boot partition.

Code:

cp /usr/src/linux/arch/[your architecture, e.g. i386]/boot/bzImage /boot/

However if this error is caused while trying to install grub. And is similar to this one:

Code:

grub> root (hd0,0)

 Filesystem type is xfs, partition type 0x83



grub> setup (hd0)

 Checking if "/boot/grub/stage1" exists... no

 Checking if "/grub/stage1" exists... no



Error 15: File not found

First of all make sure that you changed root(hd0,0) and setup (hd0) according to your systems specifications.

It may also be possible that grub uses other numbers for your drives than your kernel. So although it may be hda it could be that it is not hd0. However usually this is not the case.

Or else give this line a try provided by dirtboy

Code:

grub-install /dev/bootdevice

If all else fails make sure that your partition is not somehow corrupt. Be sure that you are able to great symbolic links.

Hope this helps.

Thank for help but maybe I have wrongly describe my problem and I have manage this problem in another way.Because my structure of HDD is as follows:
/dev/hda
/dev/hda1 ntfs (windows XP)
/dev/hdb
/dev/hdb1 /boot
/dev/hdb3 VolGroup00
/dev/hdb2
/dev/hdb5 vfat
First I have change IDE-0 to IDE1 in BIOS then I have changed in installation the order of disk(in advanced Boot ladder options) (because first was hda than hdb) and next I have entered form to option hdb and hdb1 the second one. And the system works proprely BUT!!!
I can't boot Windows

My grub.conf is as follows:

# grub.conf generated by anaconda
#
# 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.
# root (hd0,1)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title Fedora Core 5 (2.6.15-1.2054_FC5)
root (hd0,1)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.15-1.2054_FC5.img
title Windows XP
rootnoverify (hd1,0)
chainloader +1
I have made all the polsibillities of "rootnoverify (hd1,0)" line especially the content of bracket and always the system prints the massage that some error occure or just stop and do nothing.

Maybe you could help me with this problem.

I seem to remember reading somewhere that Windows likes to be on the first hard drive. Perhaps you could try asking grub to swap the drive labels for booting? I can't remember the exact command but it's definitely been posted on this site before.

But i assume that Linsnake didn't get to hit return...neither did I :p I think that Linsnake and I have the same problem. I have 2 hdds : first, primary master, hosts 2 ntfs partitions (on first, winxp, on second-> storage). Second hdd : primary slave : fedora core 5 . While installing Fedora 5 the installer offered 2 options : install GRUB on hda1 (first hdd xp partition ) or hdb (linux hdd) i selected hda1. When it boots it says : Loading GRUB Grub loading...... error 15 . :| I don't even get to see grub. :| I hope someone knows how to solve this. I think i will use some 3rd party bootloader because i have always had problems with GRUB with various PCs i have owned over the years and various linux distros :( . Since then i used lilo. But last night i didn't see lilo available :( . If i figure this out, Linsnake you'll be the first to know :P

one more thing see http://www.geocities.com/epark/linux...w2k-HOWTO.html and
make form point 3. You should manage (If I have managed:))

I thing before you will make the steps form this page you should first install one more time your windows xp because (on the master partition as previously)I think chosing in GRUB during your previous instalation of Linux hda1 you have overwritten some booting files form windows XP and because of that it don't want to run.What's more:
make 4 partition on the slave hdd

in order :
/boot ext3 112MB
/ ext3 (calculate it free space-(2*your RAM)-1GB)
swap 2*your RAM
/osshare vfat 1GB will be enough (this is to exchange the files between two os systems win and linux without any cd-roms:))

And in GRUB instal set "first sector of boot partition" and the booting files of linux will be instal on slave HDD in /boot on hdb1 partition I think.
