booting my kernel
 

Recently i compiled my own kernel for my laptop.I fixed and installed the grub-install /dev/hda1.Now when i want to boot the kernel when i chose it i get an error message saying:
The format is unregognized or unsupported.Any suggestions

Can you post your grub.conf file?

If at first you don't succeed, try, try again.

OTOH

If at first you don't succeed, you're running about average.

why '/dev/hda1' against '/dev/hda' ?
of course it is ok on condition that you have any bootloader installed on MBR.
regarding the error: looks like filesystem is not compiled into the kernel.

Below is my grub.conf
when i try to boot my kernel i get
Error 13:Unsupported mpla mpla dont remember

Well I am far from a kernel master but shouldn't you have a different initrd image for the new kernel. It looks like your using the same exact image for both kernels.

Crashed_Again is right. So just mark this line as a comment and try again.
BTW: I know that the boot process diagnostics are scrolling fast but it is your business to give us so much info as possible so next try to decode 'mpla mpla ...' :)
