Today I replaced my win98 partition with winxp (wanted to test captive acces to ntfs and still need win sometimes for specific programs that dont have linux alternatives)
I thought I restore the MBR with liveCD and kanotix-installer, but when I
tried that I got error:
Could not mount /tmp/root-23257/win partition within /dev/hda3!
Maybe this has to do with the setup of my partitiontable:
hda1 /boot
hda2 /windows
hda3 /root
hda5 /home
Does anybody know how I can manualy restore my MBR so I can boot kanotix again? |

| Did you restore the MBR to the Kanotix partition, it might be a good idea to post your menu.lst. While others have had luck, I stll think "captive" can bork your system |

do you mean , mount only root partition (= / /dev/hda3) and not /boot (=/dev/hda1) before I do :
grub-install --root-directory=/media/hda3 /dev/hda ? |

his Part. list has a missing / as root-fs. So he cah restore his mbr as often as would. He will get this errors very time he wantes to boot.
Look at his 1.st post what kind of partitions are available.
#########################################
Maybe this has to do with the setup of my partitiontable:
hda1 /boot # Ok here reisdes vmlinuz and /grub/
hda2 /windows # here windows boot
hda3 /root # Home of user ROOT
hda5 /home # Home of other users
#########################################
where is hdaX / ? # wher the rest dirs should go like /etc /proc /sys .... |

Wouldn't "/etc /proc /sys ..." go to hda3 /root or no
I am confused |

Fixed! I followed john's advise but that didn't work the first time.
Now I booted from liveCD and mounted /dev/hda1 and /dev/hda3 and then
copied everything from /media/hda1 to /media/hda3/boot and after that opened a root console and:
grub-install --root-directory=/media/hda3 /dev/hda
then a reboot and MBR was ok again , could boot to kanotix and winXP again.
Thanks everybody. |

Piper, the main-directory in all *nixe is / and is called ROOT
from this point all other subdirectories and mount-points live under /; /etc # where the conf-files are found.
/boot # where grub kernel.. resides.
/root is the exception it is not the ROOT of the Partition, but the home-directory from user=root
when / is missing on a partition from where will you got the infos storing loading Programms etc..
you need a mountpoint / to get linux to work. |

I see, and feel embarrassed on this, pretty simple and I misunderstood completely, thanks for pointing that out to me, it cleared things up for me on this matter, what was I thinking  |

@piper, doesn't matter. first when I read the orig. post, it was a bit missleading, by 'how to restore a mbr'.
normaly rewite this with grub-install or when win should used as the only OS, boot with win-cd and while in repair-mode fix-mbr and/or fix-boot does the job.
The wall was to large to see the door. Next the other a. for the fist post 'taped the door with not helpfully infos'.
The handling of directories and their structure thrue boot, was blown away.
I only do the comments which line is right, and at last I asked for the root of the hd where the struct. for dirs is put.
May be we should use a wallpaper with the structured boot-proccess.
The Q. to others with good drawings: Who can make the wallpaper? |

Do you mean of a typical Linux directory tree? Here's a starting point.
There's an old (1999) book named Learning Debian GNU/Linux that O'Reilly has online as part of its "open books" with this graphic:
Page URL: http://www.oreilly.com/catalog/debian/c ... pa_01.html
Things haven't changed a whole lot. The thing that's hard for people to understand is that there's one partition mounted as / and all other partitions are mounted on "mount points" (directories) below it, like an upside-down tree. These days, usually in /media, instead of /mnt. |

I found this on a website:
11. I have a separate boot partition on GNU/Linux (or another UNIX-like system), and GRUB seems not to handle this situation correctly.
This is often reported as a bug, but this is not a bug really. This is a feature.
Because GRUB is a boot loader and it normally runs under no operating system, it doesn't know where a partition is mounted under your operating systems. So, if you have the partition /boot and you install GRUB images into the directory /boot/grub, GRUB recognizes that the images lies under the directory /grub but not /boot/grub. That's fine, since there is no guarantee that all of your operating systems mount the same partition as /boot.
There are several solutions for this situation:
1. Install GRUB into the directory /boot/boot/grub instead of /boot/grub. This may sound ugly but should work fine.
2. Create a symbolic link before installing GRUB, like cd /boot && ln -s . boot. This works only if the filesystem of the boot partition supports symbolic links and GRUB supports the feature as well.
3. Install GRUB with the command install, to specify the paths of GRUB images explicitly. Here is an example:
grub> root (hd0,1)
grub> install /grub/stage1 d (hd0) /grub/stage2 p /grub/menu.lst
Now in my situation, /boot on /dev/hda1 and /dev/hda3 as root partition,
would suggestion 3 be right or should it be altered and if so, how? |

John,
I tried another distro which I didn't like but it overwrote my mbr. I came and did a search, followed your directions and now have my kanotix mbr back. Just want to say thank you.

piper,
I could have if I had remembered where to find it. I loaded the liveCD and looked around. I guess I missed it. Where would it be? in case this happens again.

Okay, I will respond as soon as I get the egg off of my face. I saw that but was afraid that would reinstall or repair back to the original and since I had d-u twice I didn't want to take a chance. Now I know and will feel safer when I try something new knowing I can get back to kanotix.
Thanks again, piper

hi everyone, im jumpin on this thread that looks like the problem im having. its been a while since i posted here.
it all started when i installed xp pro in a second hd (slave) next to the other hd with ubuntu dapper in it. i disconected the ubuntu drive to install since it kept telling me to install in the end of the hd with ubuntu on it (master) so i disconected the ubuntu drive and installed, it went ok, then i concected the master drive and the slave drive together and windows came up again and could not boot ubuntu. so then i played with the rescue cd from ubuntu succesfuly booting the ubuntu partition after changing the grub settings from the rescue cd and making it start with the mbr. so ubuntu came up but xp did not. so i thought to use a different distro and see if that would work, so i like kanotix and wanted to use it as well in the same machine. so i installed with ext2 (i think its called) since ext3 wasnt availble i imagine because i used it in the ubuntu partition?, anyway at the end of the kanotix install i had the kanotix and the xp partition at the choosing window at boot. so at least i had 2 out of 3. but i cant get to have ubuntu load with the other two at grub boot choosing screen. i hate to bother but i guess i cant solve this with out help. thanx
armando
ps
the kanotix install lives in the 30 last gb of the master hd next to the ubuntu install, the xp partition lives in a separate hd in the first 40 gb, there are 40 gb free at the end.
thanx again |

Fixing this should be quite easy: Just copy the boot stanzas needed for Ubuntu from /boot/grub/menu.lst on the Ubuntu root partition and add them to /boot/grub/menu.lst on your Kanotix partition.
If you need assistance with this procedure, please post both menu.lst files and the output of
Code:
su
fdisk -l
so I can see the partition layout.
P.S.: I'm pretty sure your Kanotix partition is formatted ext3 or reiserfs because the installer doesn't use ext2. Just see for yourself:
Code:
cat /etc/fstab

sorry but am more of a mac guy and know somethings about linux but i dont know how to get the stanzas from ubuntu /boot/grub/menu/lst, since i cant really boot ubuntu as my computer and my knowledge stand. i really thank you (and anyone else) 4 helping me.
also i forgot to mention that the version that i used to install kanotix is kind of old here is the reading of uname:
Code:
uname -a
Linux KanotixmandoBox 2.6.14-kanotix-9 #1 PREEMPT Wed Dec 28 10:17:53 CET 2005 i686 GNU/Linux
so it is formated in ext2, since its an old version, (how bad is this?), i guess i did worst by installing kanotix, but i was hoping to use it anyway, is ext2 a bad format?
thanx again.

There's nothing wrong with ext2, but ext3 and reiserfs are more advanced in that they support journaling, which speeds up data revovery after a system failure. They have other advantages as well, just search Wikipedia for ext2, ext3 and reiserfs to obtain more information.
Your drive setup is somewhat unusual because you installed Windows on the slave drive. But if it boots o.k., there's no need to change anything. In order to restore your Ubuntu install, I need to know the contents of /boot/grub/menu.lst on your Kanotix and Ubuntu partitions. Just boot your computer off the Kanotix LiveCD and open these files with Kwrite. Then copy the contents and post them in the forum formatted as "Code". |

hi again, i decided to reinstall everything, since it seems like its a mess. i tried to boot the xp partition and all it does is reboot and come back to the page were u select the system u are going to boot, also i could not find the ubuntu root either with kanotix live cd or with the kanotix partition. all i could see was the xp and the kanotix partitions, when i opened the ubuntu partition (or the one i thought it was root) all i could see was the lost and found folder. luckily i did find the ubuntu home partition so i took my documents that werent saved in a cd and burned them. so now i can just reinstall the correct way, dont know if i will include xp in it. since i was happy with just linux in it. thanx for the help.

| Hi djroadrash, actually a reinstall was not needed and was a easy fix, ockham23, just needed to see the menu.lst from /boot/grub from Ubuntu so you can edit it to /boot/grub/menu.lst on kanotix for kanotix, ubuntu & windows to show up in grub boot up. Kanotix will always show windows partition if you "don't" edit the menu.lst file. I would install windows first, (if you paln on reinstalling) then ubuntu and then kanotix, install ubuntu to the "root partition" and not the MBR so that ubuntu can be added to the kanotix by easily editing the kanotix menu.lst |
