I've encountered the same error on my first boot up of lfs. Edit your lfs entry in grub with (root=/dev/sda8) as the boot option "root" to (hd0,7). Below is the entry for my lfs build and it is on /dev/sda5.
Example: title LFS (Linux for Scratch) 6.4 root (hd0,4) kernel /boot/lfskernel-2.6.27.4 root=/dev/sda5 savedefault boot My fdisk, Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x58455f47 Device Boot Start End Blocks Id System /dev/sda1 1 261 2096451 82 Linux swap / Solaris /dev/sda2 262 5483 41945715 83 Linux /dev/sda3 * 5484 12010 52428127+ 7 HPFS/NTFS /dev/sda4 12011 60801 391913707+ 5 Extended /dev/sda5 12011 13315 10482381 83 Linux /dev/sda6 13316 21148 62918541 83 Linux /dev/sda7 21149 60801 318512691 83 Linux I hope this helps, cheers! :) On Sat, May 23, 2009 at 1:10 AM, srikanth tiyyagura < [email protected]> wrote: > I am working on lfs project .
