Hi all
I want to load linux using kernel image files only(which were taken from already installed system).
While doing like this i am getting error as ,
Kernel panic:No init found. Try passing init= option to kernel.

can anyone help me?

One of the reasons for this error is change in Hardware. Since you took the kernel image files from another system hence this error.

thanks for the reply. Both hard disk are running in same system.
But the error is coming.

init needs to be set for the new location in the system...., not the best way to do things...

I am copying the image files from SATA to PATA. what i thought is, In PATA itself new location will be assinged to init.
When i booted the PATA, i just unplugged the SATA drive. Here the problem is the root file system.
While booting,
getting message as,
Mouting root filesystem
switching to new root,
then only error as Kernel panic:No init found. Try passing init= option to kernel.

thats self explanitory, no "init" found,
you dont have init in the location that the boot loader is looking, and more than likely kernel is set for init to be in another location as well..
moving an installed image from one type(sata) drive to a totally different drive type(ata) can cause total caos to the install...
its not just a case of having the correct drivers, but altering the whole install to recognise the location difference...
I would be inclined to fresh install the ata and then transfer all data from the sata drive...insuring that the first boot drive is the new one...

Thanks for your reply.
My goal to boot a linux by copying kernel images.
Thats why i have copied the images from already installed system. am i missing any other files for booting?
