error booting after grub

[loft306]

Ok there is your problem right there you didnt edit the /dev part of /etc/fstab as stated in the handbook to apply the real device names to replace

/dev/BOOT

with the correct

/dev/hda1

and

/dev/ROOT

with

/dev/hda3

&

/dev/SWAP

with

/dev/hda2

as stated in this chapter in the gentoo handbook http://www.gentoo.org/doc/en/handboo...ap=8#doc_chap1
along with any fs types and options nessasary

and on the grub.conf everything there checks out with what is in /boot so that is ok.

Just go ahead and fix the above and you should boot rite up!

im pretty sure i didnt do most of the things your talking about and if i did it was probably wrong

but heres what you asked for the fstab thinggy

but when i compiled the kernel i chose the pentium4-2.6.12 something, im pretty sure of that.

Now the problem is all too clear. You never set up your /etc/fstab file correctly.

Boot back up with the Gentoo install CD, mount the partitions as before then do nano /mnt/gentoo/etc/fstab.

The options in your /etc/fstab where is says:

/dev/BOOT
/dev/ROOT
/dev/SWAP

You need to change those to reflect the actuall locations. If you followed with handbook exactly it would be something like:

/dev/hda1
/dev/hda3
/dev/hda2

If you need more help with this, re-read Chapter 8 of the handbook.http://www.gentoo.org/doc/en/handboo...ok_part1_chap8
Once you get these correct the system should boot no problem.

my fstab should be ecactly like you guys are saying and like the handbook is saying in chapter 8.

This is perplexing

what is the output of

cat /boot/grub/device.map

and is the error exactly the same? or did it change slightly? either way could you paste it again please

And also once you are chroot'd into your install please paste the output of

cat /usr/src/linux/.config | grep CONFIG_EXT3_FS

even though you used genkernel it may of missed support for the ext3 filesystem

[nimwa2]

the error is exactly the same its asking for root device as before

>>Activating udev
>>determining root device...
!! The root block device is unspecified or not detected
Please specify a device to boot or "shell" for a shell...
boot() ::



my device.map output:

(fd0) /dev/fd0
(hd0) /dev/hda

my CONFIG_EXT3_FS output:

CONFIG_EXT3_FS=y
CONFIG_EXT3_FS_XATTR=y
CONFIG_EXT3_FS_POSIX_ACL=y
CONFIG_EXT3_FS_SECURITY=y

any idea what i could do? or should i just try to install all over again?

I got exactly the same issue. I also got a lot of other issue (i'm using a pretty non standard setup - bootable RAID 1 setup on intel ich6r using SATA hdd).

unfortunately i do not remember how i solved this exact one. but basically the problem is that initramfs is being loaded correctly, but that is unable to load the kernel properly.

one of the things i did was to remove the space in line (from your grub.conf)
"root (hd0,1)" changed to something like
"root(hd0,1)"

I'm not sure why but this fixed one of the first problems i got. surely woth trying.


the grub.conf file to change would be in /mnt/gentoo/boot/grub if you have not chroot'ed but mounted the partitions.

HTH.

[nimwa2]

it didnt really fix it. ive set root to hd0,1 and in my fstab ive set it to hda1 but is there a possibility that my kernel or boot thinggy is not even in hda1??
