vorticies82,
Please post your grub.conf. Its much easier to spot an error that to try to second guess what you might have done.
I will guess though
You only changed the title=. The kernel line points to the old kernel.

| Ok, I managed to fix it through trial and error. For some reason, it is looking for my grub directory in /boot/boot/grub instead of /boot/grub. I put my new config file there and now it works fine. How would I go about changing grub to look in /boot/grub instead of /boot/boot/grub? |

Hi.
You should have your kernel line in /boot/grub/grub.conf as /boot/kernel* and you seem to have removed the symlink /boot/boot to /boot. You just need to remove the /boot/boot dir and make a symlink in /boot to itself as
| Code: | # rm -R /boot/boot
# cd /boot
# ln -s boot . |
If you create anything inside /boot/boot/grub you should first copy it to /boot/grub.

Hmm I have a really weird one for all of you... When I start up I have to put the chainloader +1 to boot into windows. For some reason the chainloader +1 does not show up in grub even though i have it saved.
Here is my grub.conf
default 0
timeout 10
splashimage=(hd0,1)/grub/splash.xpm.gz
title=Gentoo
root(hd0,1)
kernel /bzimage root=/dev/hda4
title=Gentoo2.6.12
root(hd0,1)
kernel /kernel-2.6.12 root=/dev/hda4
title=Windows
root (hd0,0)
makeactive
chainloder +1
The chainloader +1 is listed and I cant boot into windows unless I edit the line in grub.
Thanks in advance |

How about changing root to rootnoverify? |

Nope no such luck...  It does does not work. This might help any other changes to the grub.conf file are saved and show up in grub but when you try to boot windows the chainloader +1 is not added to the windows option.
Thanks so far. |

|
|
Im installing Gentoo on a friends computer and everything seemed to go fine until we rebooted and Grub started to load. It gives an Error17 which i found out means the partition exists but it cant mount it. The grub.conf file is:
| Code: |
default 0
timeout 30
splashimage=(hd1,2)/grub/splash.xpm.gz
title=Gentoo Linux
root (hd1,2)
kernel /kernel-2.6.12-gentoo-r4 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hdb1 udev
initrd /initrd-2.6.12-gentoo-r4
title=Windows XP
root (hd0,1)
makeactive
chainloader +1 |
The root parititon is /dev/hdb1 and the boot is /dev/hdb3. Windows is installed on /dev/hda2. Grub was installed using grub-install /dev/hda, was that right? Should it have been grub-install /dev/hdb? If its wrong how can we uninstall grub from /dev/hda and get it on /dev/hdb?
Edit...well we fdisked the mbr and reinstalled grub on /dev/hdb, but we get the same error.

Does it make any difference if you spell chainloader correctly ???. |

Guilty_Spark343,
You may have a broken keyboard too - your post was in all capital letters. Thats condsidered to be shouting. Please don't do it.
Anyway, on to your problem. info grub says
| Code: | 8 : Kernel must be loaded before booting
This error is returned if GRUB is told to execute the boot sequence
without having a kernel to start. |
You probably have an error in your grub.conf file. Check it over. Post it here if you want us too look it over with you.
Please don't shout again.

Sorry about the thing of the capital letters, i wont do it again.
Right now im at work, but ill post the grub.conf file here as soon as i get to my home, thats at night, but ill do.
Isnt there a way to load the kernel from the grub prompt, or im just saying stupid things??
What do i have to do in order to look to my grub.conf file using the cd?, cause its obvious i cant see it if im in the grub prompt. |

| Posted: Mon Jul 11, 2005 10:09 pm Post subject: Yet another dual boot question |
|
|
I recently moved from fedora to gentoo and I'm having difficulties booting my WinXP partition. I was able to dual boot just fine under fedora, but foolishly didn't save my grub configuration. Windows is installed on the second partition of hda and the first partition is the Dell utility partition. Gentoo is on hdb.
Here's all the relevant info I could think of:
| Code: |
root@kepple ~ # tail -n 5 /boot/grub/grub.conf
title=Windows XP
rootnoverify (hd0,1)
chainloader +1
makeactive
root@kepple ~ # fdisk -l /dev/hda
Disk /dev/hda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 4 32098+ 16 Hidden FAT16
/dev/hda2 * 5 4862 39021885 7 HPFS/NTFS
root@kepple ~ # fdisk -l /dev/hdb
Disk /dev/hdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/hdb1 1 5 40131 83 Linux
/dev/hdb2 6 130 1004062+ 82 Linux swap / Solaris
/dev/hdb3 131 19457 155244127+ 83 Linux

Hi.
I would take the boot flag from /dev/hda1 and although it shouldn't be relevant, I would swap the chainloader +1 line with the makeactive in /boot/grub/grub.conf.
You didn't misteakingly tried to install GRUB in (h0,1), did you? If so, you cleared your Windows boot loader. In that case, you'll have to start with the XP installation cd, choose the recovery console and run fixboot. Hopefully, that'll do the trick.

Thanks for the suggestions Jorge. I tried both, but to no avail. When I try to boot windows grub just prints out the entry and hangs. I really don't think I accidentally installed grub on hda, but I'll try to dig up my windows disk and see if that fixes it.
Thanks for you help, and if you have any other ideas, let me know. |

I loaded the kernel manually from the grub prompt, but after the system starts to boot, it comes up with the following:(:
VFS: Cannot open root device "sda3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel Panic -not syncing:VFS: Unable to mount root fs on unknown block(0,0)
How do I solve this  ???
My partition is as follows:
/dev/sda1 = boot
/dev/sda2 = swap
/dev/sda3 = root
Thanks for the help |

@romalong,
can you post the remaining output from GRUB? Did you look at the first page of this thread and tried what is suggested for the error 15?
About the entry in /etc/fstab for mounting windows partitions, if you have NTFS, you can use something like
| Code: | | /dev/sda3 /home/win ntfs noauto,user,uid=atlantis,gid=users 0 0 |
This is what I've been using for years. I've recently been told about the use of umask and after reading the man page for mount, I would suggest that you use instead
| Code: | | /dev/sda3 /home/win ntfs noauto,user,umask=000 0 0 |
if you want more than one user to have access to the disk. If you want any user to be able to unmount the disk, even if he/she didn't mount it, you should replace user with users.

1. You're welcome.
2. Doesn't GRUB say anything else besides what you've posted? I would assume that you get some extra info. We need that to help you.
3. Don't you want to mount them? That's what I undestood from
| romalong wrote: | | also what should i enter for windoz in fstab? |
your comment.
4. Ah. I was confused by your mixing of /etc/fstab and /boot/grub/grub.conf. What you want is
| Code: | title Windows XP
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
makeactive
chainloader +1 |
Assuming that your windows boot partition is in /dev/sdb1 or /dev/hda1.

do i actually need to use these map(s)?
bthw, i couldn't boot windows as well 
my sdb drive has got three partitions, the first one has got MBR for windoz and FreeBSD (not present now), could this interrupt GRUB to boot windows?
the sda drive is only for linux and the system is going to use its MBR for both OSes |

Ok.
In that case post the output of

| Code: | # parted -s /dev/sda print
