ive installed up to the bootloader and rebooted the computer. grub loads and i boot gentoo. it goes a bit and then stops and says "kernel panic - not syncing : VFS : Unable to mount root fs on unknown-block(1,0)"
what should i do?
thanks

You're using Grub?

I think that it's saying it can't mount something at the first partition of the second HD.

I dunno the exact problem, but you may want to go back into your GRUB config and double-check all the HD values you gave.

Remember: 0,0 is /hda1 and 1,0 is /hdb1.

Agree with Cabhan - it definitely sounds like a GRUB issue. Post the contents of your /boot/grub/menu.lst file if you can.

Along with your menu.lst, you will need to post your ./etc/fstab

i am having the same problem....so i thought i would horn in on your helping...the only thing i have added to the default config for genkernel is trying to mount my second HD in fstab and changing the timeout to 15 from 30




my /boot/grub/menu.lst looks like:

default 0
timeout 15
splashimage=(hd0,0) /grub/splash.xpm.gz

title=Gentoo Linux 2.6.12-r4
kernel /kernel-genkernel-x86-2.6.12-gentoo-r4 root=/dev/ram0 init=linuxrc ramdisk=8192 real_root=/dev/hdb3 udev vga=0x317 video=vesafb:mtrr,ywrap


+++++++++++++++++++++++++++++++++++++

my /etc/fstab looks like: (i am leaving the commented lines out since i am re-typing not copy-paste-ing)

/dev/hdb1 /boot ext2 defaults,noatime 1 2
/dev/hdb3 / ext3 defaults,noatime 0 1
/dev/hdb2 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,ro,user 0 0

/dev/hdd1 /home auto defaults,noatime 0 2

none /proc proc defaults 0 0

none /def/shm tmpfs defaults 0 0


+++++++++++++++++++++++++++++

now my mobo is OLD...so it doesnt recognize my main HD as hda, the bios labels it primary slave, with no master...there is only one hd on the primary ide ribbon, the secondary has the cdrom as master and the HD as slave, thus the hdb and hdd and no hda's


thanks for any help or insight you can give me...

One problem I can see with your config is the line:

"splashimage=(hd0,0) /grub/splash.xpm.gz"

in menu.lst

Assuming that it's supposed to be pointing at the /boot partition, it should actually read:

"splashimage=(hd1,0) /grub/splash.xpm.gz"

You have it pointing to /hda1, which doesn't exist.

thats what i thought , but when i changed it to hd(1,0), it will hang at boot doing nothing but a black screen and then eventually reboot to repeat the process...i think that (hd0,0) is what i need, because even though it doesnt seem to make sense the little penguin icon shows up that the splash image is pointing to during boot, it's just that once it goes far enough in the boot process i get the kernel panic error, preceded by "UDF-fs No partition found"...i cant even ctrl-alt del...i have to reset with physical button....

You seem to be missing a root line for your kernel.

[intellect]

i am not sure what that means or how to fix it....
