Facts: hda1 ntfs primary
hda5 ntfs (logical in ext.)
hda6 fat "
hda7 fat "

I removed hda6 to install linux (partitions renumbered):
hda1 ntfs
hda5 ntfs
hda6 fat
hda7 ext3 (/) mdk
hda8 swap
hda9 ext3 (home) mdk

Then I removed hda6 (fat) to install another linux flavour (partitions renumbered again-normal):
hda1 ntfs
hda5 ntfs
hda6 ext3 (/) mdk
hda7 swap
hda8 ext3 (home) mdk
hda9 ext3 (all in one) rh

Now after chaging menu.lst with the proper changes in kernel and root I got: INIT NOT FOUND, TRY PASS INIT= OPTION TO KERNEL when trying to boot mdk.
Now I know there is internal reference to the partition numbers where the system was.

Could please anybody tell me if there is a easy way to fix it up?
thanks, never happened before.

When you move partitions around (or renumber them) you have to change you bootloader (either lilo or grub) to tell it where / is now located. You also have to change /etc/fstab to tell where all of the partition mountpoints are.

Thanks for replaying.
I've updated fstab:
before after
/ hda7 hda6
home hda9 hda8
var hd10 hda9
swap hda8 hda7

I updated menu.lst :
kernel (hd0,5)/boot/vmlinuz root=/dev/hda8 init=/dev/hda6 mount=devfs acpi=off vga=788
initrd (hd0,5)/boot/initrd.img

Still getting these errors:
pivotroot: pivot_root(/sysroot, /sysroot/initrd) failed: 2
Remounting devfs at correct place if necessary
kernel panic: No init found.try passing init= option to kernel

If I try booting without initrd.img (I hate initrd.img always comment this line) get these ones:

Instead of pivotroot:
mount-devfs-fs():unable to mount devfs, err=-2
warnig: unable to open an initial console
kernel panic: no init ...

I appended init=/dev/hda6 to no avail like kernel options.
If I mount the partitions from the other linux everything seems fine.
thanks for your help.
Can I do anything more to fix it up?
------------------------
why newbie people like me never think the right way?
I've read fstab hundreds of times just because I like to mount devices from command line (I do not like supermount or automount or ...)

ok everything fine now.
LINUX IS BOOTING.

In menu.lst there was an error ( mine of course). The kernel option root must say the root / and this is hda6 not hda8 that is /home.
Change the root option and linux is working ok.
thanks a lot jailbait (song of ted nuget, isn't it).
