he is telling as follows............
{
root (hd0,0)
filesystem type is ext2fs, partition type 0*83
kernel /boot/kernel-2.6.21.5 root=/dev/hda1

Error 15:file not found

well sir i'm doing the lfs on slackware 12.0 thanks in advance

Who is saying these things?
Is this what you get when you try to boot a new kernel?

Check your assumptions:
Maybe the kernel is not in (hd0,0) ... i.e. hda1? Do you have a separate /boot partition?

yes this what i get when i select the host system at the boot menu of LFS



ya i have check the boot of the slackware 12 and the os is fount in the hda1....i have use (had0,0) in the boot menu...is it the prob abt the kernel's name???

Well, what you see is grub's boot menu. grub is the bootloader, it is used to load you operating system(s), Slackware and LFS in your case. grub is looking for the LFS' main component -- the Linux kernel. Kernel is a file located somewhere on your hard disks. Hm, it looks like we don't know where you put it.
First. Did you compile it at all? If so, did you name it properly (name "kernel-2.6.21.5" does not correspond to any version of LFS book)? Check this. Did you place it in the proper location? The last LFS (v. 6.3) says the file should be named "lfskernel-2.6.22.5" and be placed in /boot directory of the LFS partition. Check this, too, and reply.

i have compiled the lfs kernel and it is lfskernel-2.6.22.5 its the 6.3 version that i'm using...i can get the lfs interface when i select the lfs option in the menu...the prob is that i caan get the interface of the slackware 12.0 .

it give me the error in the post above when i select it..my prob is with the slackware to boot....

can u help me plz...

That should be easy, unless you did something to your Slackware. All you have to do is to:
1. Boot into LFS;
2. Mount all the disks/partitions that can potentially contain the Slackware's kernel;
3. Locate the kernel file (I don't know much about Slackware, so I'd suggest you first look into /boot and /boot/grub directories);
4. Edit the grub menu file (probably /boot/grub/menu.lst on your LFS partition) to contain the correct path to Slackware kernel.

Hope this helps (c) druuna
