Grub Error Collection [Part 3]

Hi Nimlot.

How did you copy your kernel to /boot? Did you copy the bzImage file or did you copy other file? Please post the contents of your /boot dir. Do ls -l /boot if you chroot or ls -l /mnt/gentoo/boot outside the chroot.

I copied the bzImage like so:

Well, you clearly have a problem with your kernel file. No regular 2.6 kernel is only 26Kb!!! As a comparison my hefty 2.6.12 for my AMD64 is 2.5MB+. You should confirm that you hadn't a problem copying the file or that make completed sucessfully the compilation of your kernel.

Thanks, something must have gone wrong the first time I compiled. Recompiled and works fine now.

nihil39,
have you tried reinstalling GRUB into the MBR? In your case, you would need to do

Sorry, my misteak! :oops:

It's quit, instead of exit.
I still can't imagine what is causing your error. Can you copy & paste your grub.conf file? It seems ok, but just to be sure.

Right.

Been looking through this tread and cant seem to find an answer to my troubles.
My HD partition scheme is as follows:

sniggit,

there was a post in the last 48 hours in this forum with the same question. Basically, you've enabled support to boot from NFS and have to disable it. You can check that in https://forums.gentoo.org/viewtopic-p-2913755.html#2913755
I've also seen that you've started a new thread in https://forums.gentoo.org/viewtopic-t-407557-highlight-nfs+boot.html . Never double-post.
I'm going to ask the moderators to merge the threads.

SOrry for the noob question, but I'm not sure what HD values to put in the following code.

hda1 is my windows drive (with MBR)
hda6 is my boot
hda7 is swap
hda8 is root

I'm assuming the hd0,0 do not apply to my configuration, but i'm not sure how to do it correctly.

Well I have try to install a lot of times and always failed and give up. This Friday, I said to myself to give it another go. From Friday to yesterday, I have installed and re-installed probably more then 10 times from different errors to network problems. When it did installed, I get the stupid GRUB GRUB GRUB all over the screen after reboot. So I said to myself, probably I did something wrong and re-install it again and same thing happens. Until 2:00am this morning, I start looking for answers. I finally figure it out. Because I had install GRUB previously, and have to remove it first. So I use LILO to wipeout Grub. Load and behold after it reboot and now it displays only LILO all over....

After further investigation, i realize that the BIOS is set to Auto to detech Harddrives which is a no no. After changing it to User Type, everything works. Now I have to install xdm, gnome, kde.....

Molum,

Reinsalling is a bad habit users aquire from another operating system.
You can use your liveCD to recover a gentoo sstem that won't boot by doing the following.

1. Mount your partitions as per the handbook, including proc and swap (swapon)
Do not use fdisk or mksf because you partitions and filesystems are OK

2. Run chroot /mnt/gentoo /bin/bash
and the following two commands from the handbook.

Your system is now back exactly as it was before you rebooted and it didn't work.
You can fix it from here ... and try again.
No reinstall required.

hey guys,
i dont know if this is a problem with grub, but it has to do with it

ok first:
i have two hdds:
1) hda, on which linux is installed
2) hdd, on which winxp is installed
well ... after a successful compilation of a new kernel, i copied it into my boot partition and then rebootet. but instead of entering the grub menu i only got an error that i should insert a boot disk ... after a few reboots it still didnt vanish, and i eventually came to realize that both my mbrs were corrupted ... so i put in my winxp cd and easily repaired the mbr of my windows hd. but unfortunately i have no bootable linux medium :O ( and no, there is no chance of burning a bootable linux cd, i tried it like 100 times, but my system never boots a cd i burn ). now im here on my windows box trying to repair my hda's mbr.
first i had a look at my mbr. i used a program ( mbrwiz ) to read the partition table of hda. it seems to be correct. and the last two bytes are h55aa so this is correct too. that means, something has to be wrong with the first 446 bytes of the mbr. following i copied the mbr to a file and i merged it with /boot/grub/stage1 ( i dont know if this can work at all

) ( the first 446 bytes taken by stage1 and the table taken by the original mbr ). then i wrote it into the mbr.
now, every time i try to boot with grub i only get "grub grub grub" and so on ... i have already tried the hint with setting user type hdd in bios but it didnt change anything.
so my questions:
1) can this way actually work ?
2) if yes what did i do wrong ?
3) if no: is there another way i can repair my mbr ? do the first 446 bytes always look the same ? if so can someone give me his/her mbr ? XD

well, i dont know if there is anything else to say. as always, english is my third language, if you dont understand me or if you need additional information just ask me again

was auch immer,

Grub MBRs vary from user to user. The MBR has the location of stage1.5 hard coded into it at grub install time. There may be other differenceces too. Its unlikely you can patch up your MBR.

Any linux bootCD will do to rescue your install, such as a magazine covermount, even a boot floppy.
You can use a DOS boot floppy with loadlin and a kernel too.

Its unlikely installing a kernel even a broken one, will make a mess of your MBR.

I dont know if someone posted this already, but can someone just show the layout of what a finished grub.conf file looks like?

NeddySeagoon · Posted: Fri Dec 09, 2005 7:41 pm Post subject:

moddolicous,

Everyones grub.conf is different. There is a sample in yor install at /boot/grub/grub.conf.sample and the one that goes with the install, as per the guide is at http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=10

Thanks NeddySeagoon. So what should I type to see the grub.conf.sample? Would I just type grub.conf.sample? If it helps I'm not using genkernal.

moddolicous,

If you are booting from the liveCD, (I assume you are because you need grub working to boot normally)
You must first mount your partitions as you did at the beginning of the install. Thats the
