Just ommit the /boot in your kernel... command.
If you would like to create the symbolic link you would have to type or was it don't know. I always get it wrong. anyhow only one should succeed. checkout if you want to know more.

|

There is a new version 0.94 of grub available, that fixes broken boot of grub 0.93.20031222 which did always boot into the grub console. (See: Bug 39392)
However this comes at a price: Background images for grub are broken with 0.94  |

OK, I'm still having the same problem I was having. I've confirmed that grub, fstab, and my kernel compiles were pretty much correct.
The configs are exactly the same as I last posted them, except I replaced my reiserfs partition with ext3. The contents of my boot directory are...
System.map-2.6.1 boot config-2.6.1 /grub kernel-2.6.1 /lost+found
Contained withing the grub directory are....
e2fs_stage1_5 ffs_stage1_5 grub.conf.sample minix_stage1_5 splash.xpm.gz stage2 xfs_stage1_5 fat_stage1_5 grub.conf jfs_stage1_5 reiserfs_stage1_5 vstafs_stage1_5
The lost+found directory is empty

I have one small suggestion. Here:

- Cannnot open root device "hdaX"
Are you getting something like this error?
| Code: | VFS: Cannot open root device "hda7" or 03:07
Please append a correct "root=" boot option
Kernel Panic: VFS: Unable to mount root fs on 03:07 |
Make sure your grub.conf reads two times the same (hd0,X) entry. like | Code: | root(hd0,1)
kernel (hd0,1)... |
|
From my expierience, this is 80% of the time caused by an incorrectly configured kernel, specificly either:
[+]IDE chipset (or SCSI controller) support not compiled or compiled as a module (and no initrd).
[+]filesystem support used on root partition not compiled or compiled as a module (and no initrd).
[+]support for MSDOS partition tables not compiled (CONFIG_PARTITION_ADVANCED -> CONFIG_MSDOS_PARTITION)(it happened!)
On fresh installs it's often caused by not having edited /etc/fstab during the install process, and it still contains lines like "/dev/ROOT / ext2 defaults,noatime 0 0".
Solution for both kinds is obviously rebooting the LiveCD or, in the former case, just a sane kernel and fix the configs.
HTH |
well, i'm having troubles with that
[img]www.felipebas.brturbo.com/Gentoo1.png[/img]
it's a fresh install under vm-ware, that emulates a scsi controller/drive
fstab:
[img]www.felipebas.brturbo.com/Gentoo2.png[/img]
grub.conf:
[img]www.felipebas.brturbo.com/Gentoo3.png[/img]
i'm not quite sure that the scsi controller was compiled, either the support for MSDOS partition tables... how can i see if it those two things were compiled, and if not, how can i fix it?
i'm a noob... remember that when you answer this post |

It considers my hard drive as "hde" because it's a seperate ATA bus (2 normal IDE, and 2 ATA100 on my motherboard, and I made sure to enable the chipset in the BIOS).

0.94 does NOT fix the - boot to grub command line issue.
you'd think it was tested first, does the developer use lilo? yes, nasty dig... but honestly... |

I am getting the 'cannot open root device...error
i have tried everything in the forum and i have gotten nowhere. i have even emerged grub .94
my boot is ext3, root is reiserfs, both compiled into the kernel. msdos, vfat, ntfs in the kernel as well.
i am using gentoo-dev-sources.
grub.conf
| Code: |
default 0
timeout 30
splashimage=(hd1,0)/grub/splash.xpm.gz
title=Gentooooooo!
root (hd1,0)
kernel (hd1,0)/bzImage root=/dev/hdb2 vga=791
title=Windows XP
...
|
fstab
| Code: |
/dev/hdb1 /boot ext3
/dev/hdb2 / reiserfs
/dev/hde1 swap
/dev/hda1 /mnt/windows ntfs
/dev/hde2 /mnt/mediatank vfat
/dev/hdf1 /mnt/isotank vfat
|
what am i doing wrong? is there something that i need to pass for reiserfs? |

Can you verify these?
| Code: |
$ cat /usr/src/linux/.config | grep DOS_PART
CONFIG_MSDOS_PARTITION=y
|
Gives me "0000:00:07.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT8233/A/C/VT8235 PIPC Bus Master IDE (rev 06)". Check your kernel config to support yours." |

i get this error, 0.94 did not help me 
i did start from stage3 install, i did update it...upgrading grub did not help...i know it works correct when starting from stage1 install, how odd that seems to be... |

Try the lspci command as root
-nbrown
BTW, I'm having the same VFS please append an appropriate root option error too. Here's another thread where I found it first. If any one has any ideas please drop a note in either of these threads. |

ok... let me fly my n00b banner here...
after an lspci i decided to triple check to make sure that i had compiled support for my ide controler on my mobo, nforce2. it was not there.  i had added support for my silicon graphics controller for my other two hds but not the controller on my mobo. after a quick recompile i was able to boot fine and am now emerging gnome... 
other things that i ended up trying, if this helps anyone else:
downgraded grub to .92
emerged grub with:
| Code: | | CFLAGS="" emerge grub |
i had read on another thread that any kind of optimisation breaks grub.
i don't know if my playing with grub did anything. at least it is working now.
man i feel like a n00b... |

Fix for the below problem, not listed on the first page.
| Code: | VFS: Cannot open root device "hde9" or 21:09
Please append a correct "root=" boot option
Kernel Panic: VFS: Unable to mount root fs on 21:09 |
Solution: (from deepthought, many thanks) | Quote: | t's just about disabling the "Mount devfs at boot time" switch in kernel config. Or replace the "root=<something>" kernel boot option (cf. /boot/grub/grub.conf) by something devfsish, for example "/dev/discs/disc0/part3" for the harddrive normally refered to as "/dev/hda3".

It should be OK if it's in a partition of its own.

This is what I get when I boot:
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel (hd0,0)/boot/kernel-2.4.22 root=/dev/hda3
Error 15: File not Found
I know someone had a similar problem, but I couldn't disseminate how to fix it.  |

maybe it is

|
if you're using the recent gentoo-sources. Otherwise try with tab-completion or post the output of "ls ..." like ideoneus described in his very first posting. Make sure there is a boot symlink in /boot, or just try
"kernel kernel-2.4.22-r5 root=/dev/hda3"
