Fedora urgent!!!!

When it boots up, you should get an option to boot up to the previous kernel.  Right at the beginning as soon as the Fedora Image appears there's normally a 3 or 5 second count down, if you interrupt that you should hopefully be able to select the previous kernel and boot up normally and then resolv the issue.

nope only the grub screen

Hi,

I hope this will help!

Hi,

To find stage1 file in fedora use following command at grub> prompt

grub> find /grub/stage1

and then follow the instructions mentioned in my previous post.

Hi,

Output of above should look like this

grub> find /grub/stage1
find /grub/stage1
 (hd0,0)
 (hd1,0)

In my case there are two entries as i am having two different version of Linux installed, you may find only one entry.

it returned only hd(0,0)

What happens when you type

boot

on the grub prompt?

Next: your one and only partition seems to be (hd0,0), thus the kernel will reside relative to
(hd0,0)/boot
That is:

root (hd0,0)

would be right.

error 8 : kernel must be loaded before booting

HI,

Actually its a bug and you check more details over here

https://bugzilla.redhat.com/show_bug.cgi?id=450143

The best solution for your problem is to re-install grub, as follows

1. Boot  with 1 cd of OS.

2. on the prompt type
: linux rescue

3. Select language, networking options etc  and finally after booting use

# chroot /mnt/sysimage
# grub-install /dev/hda  ( use /dev/hda for ide or /dev/sda for sata)
# exit
# reboot

I am using fedora over vmware and i mounted the iso but it still directly goes to grub screen

HI,

Recheck boot option in vmware, and vmware's bios available for linux vm, right now i dont have vmware installed on my system and hence cant chk the exact booting options, still i will try to recollect meanwhile just give a try I am sure that it boots from image also.

Hi,

Found this solution on the  web  http://pctechnow.blogspot.com/2008/01/vmware-how-to-boot-from-iso-image-to.html

i am checking also please find me a way all my sites down :(

This works on irst installationf of guest os

Hi,

I dont think so, It should work later also, try once again and when it will boot from the image at the first installation screen where you use to hit enter to begin installation, on that prompt instead of hitting enter you need to type

:linux rescue

and then hit enter

Hi,

Otherwise download rescue cd for your fedora version and burn it if it is very urgent.

i have opened now in live mod there was no rescue opt. like cent os i will check from terminal

do you know how could i open in rescue mode on fedora12

HI,

When you boot from the cd there may be a menu and you need to select rescue mode from that menu.

You must boot your vmware off the fedora cd. this is either the the real cd/dvd drive connected to your system or an iso image of the fedora cd.
you can configure vmware to use the cd (image).

check this :(

Hi,

Visit http://docs.fedoraproject.org/install-guide/f12/en-US/html/s1-rescuemode-boot.html

Hi,

Also have look at "16.2.1. Reinstalling the Boot Loader" mentioned in above URL

i could not open rescue mode :(

the problem there is no boot prompt

boot from installation cd  Fedora-12-i386-DVD.iso or Fedora-12-x86_64-DVD.iso
chose rescue existing system

Hi,

I think you are using Live cd instead of Disc 1 of fc12 download it from here.

http://fedoramirror.hnsdc.com/releases/12/Fedora/i386/iso/Fedora-12-i386-disc1.iso

I am downloading now i will check in ten minutes

I have downloaded and do the things given on the site i think we are on the right way please write me an email cahit.eyigunlu @ gmail.com i will send you my remote desktop admin info please check for me it will be complete in a little trick in my opinion

Hi,

But in my opinion you should not give control of your system to anybody (Including me) as it may not secure also it might be  against the policies of Expert Exchange.

Just give a try man, im here to help you out! Dont worry. Its not that difficult.

i have got an email is not that you ?

no problem for one time i was using ee for a long time as a premium

ok then please check this out i have complete the steps as given below but when i restart server it still comes to grub
fd.png

Hit enter

# chroot /mnt/sysimage
# grub-install /dev/hda  ( use /dev/hda for ide or /dev/sda for sata)
# exit
# reboot

I have this screen but still returns to the grub :(
fd.png

Now review file "/boot/grub/grub.conf" if it looks fine type reboot.

grub.conf is empty :S

Past output of following cmds here

# fdisk -l

# ls /boot

can you do a  ls of /boot/grub/
and see what files are in there

Paste output of following cmds here

# fdisk -l

# ls -R /boot

Is /boot returns command not found
and fdisk -l result as given below

i am so sorry i take your so much time but i am very very pleasure for your help
fd.png

# ls -R /boot result

Hi,

R u sure your grub.conf is empty, try

# cat /boot/grub/grub.conf

nothing returned and i checked with vi still empty

if grub.conf is emty you can make one with vi
change the vmlinuz and initrd of this file in the last good working kernel version
in this example and it should work

Hi,

Also i do understand your situation man, i am also working on your problem just to help u out as early as possible and not just to earn the points, i could earn point by providing solution on other questions rather than spending much time on single problem!

Im also a sys and storage admin and i very well understand the ur pressure in such situations!

I wrote the grup.conf and this is the final which one do i select ?
fd2.png

i tryed both and the image adresses are wrong in my opinion where could i find the img adresses ?

Hi,

That file is of fc11 and it may not work directly, you need to change according to your environment specially following entries

root (hd0,0)
        kernel /<ur-image>  ro root=< ur root part.>
        initrd /i<ur initrd image>

Hi,

Correct image names are in ur screen shots provided earlier.

i found this 2 ->
initfarms-2.6.32.9-70.fc12.i686.img
initfarms-2.6.31.5-127.fc12.i686.img

and it returned me error 19 : linux kernel must be loaded before initrd

for both selection

can you give a screen shot of your grub.conf now ?

i only changed

initrd /initrd-2 xxxxxx
to
initrd /initfarms-2.6.32.9-70.fc12.i686.img
fd.png

The last problem encounter by this line in my opinion :
        kernel /vmlin
uz-2.6.30.10-105.2.4.fc11.x86_64 ro root=/dev/mapper/vg_harryfedora11-lv_root rhgb quiet

you should have this
title Fedora (good)
        root (hd0,0)
        kernel /vmlinuz-2.6.31.5-127-.fc12.i686 ro root=/yourdevice rhgb quiet
        initrd /initrd-2.6.31.5-127-.fc12.i686.img
yourdevice you can see with  the command  lvm lvdisplay

i also install fedora 12 to my system on another vm and i get grub.conf :

default=0
timeout=0
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.31.5-127.fc12.i686)
        root (hd0,0)
        kernel /vmlinuz-2.6.31.5-127.fc12.i686 ro root=/dev/mapper/vg_lin-lv_root noiswmd LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=trq rhgb quiet
        initrd /initramfs-2.6.31.5-127.fc12.i686.img


but that is not solved :(

how could i find the kernel sourcs

this part :

 kernel /vmlinuz-2.6.31.5-127.fc12.i686

because i tryed on the grab it returnd me file not found

under /boot see picture above

:(((((
i checked kernel is ok but i still got the kernel must be loaded before initrd
fdd.png

I found that :

I wrote kernel/vmlinuz
but it must be kernel /vmlinuz

now it returns no error but stays on black screen with only one dot ?

last screen

Take a moment to clear it all up by using the find command at that grub> prompt to locate the boot partition and see what GRUB is naming it. Example...
grub> find /grub/stage1

i am not able to return grub now but it wrote hd0,0

what do you mean  can not return to grub ?
can' t you press esc
grub> find /grub/stage0
gives ?
grub> find /grub/stage1
gives ?

for both of them error 15 file not found :(:(:(:(

you need to change root (hd0,0)
if i see it right you have 3 hard disks
do a fdisk -l
to see from wich partition and hard disk you boot

it is already root (hd0,0)  
and i have only one hdd :(

I have installed all system from the begining thanks to god my customers have their backups :D
and now i am getting daily backup of Vm disk

Thanks for your attention
