Problem at booting with new kernel

Hello

I am using debian and downloaded a new kernel 2.6.28.2 and compiled successfully using

make
make modules_install
make install

in the final step it shows " GRUB is installed. To automatically switch to new kernels, point your
default entry in menu.lst to /boot/vmlinuz-2.6.28.2rakesh "

then i updated grub with update-grub command and opened menu.lst but it does not have any

and booted my system and new kernel is not working

then i check my menu.lst

title Debian GNU/Linux, kernel 2.6.28.2rakesh Default (single-user mode)
root (hd0,5)
kernel /boot/vmlinuz root=/dev/sda6 ro single
savedefault

there is no entry for initrd.img ..

Did you forget
mkinitrd -o /boot/initrd.img-2.6.28.2rakesh

Even after adding initrd ,if you are unable to boot. Post the error messages

hi

i installed yaird and then created new img using
mkinitrd.yaird -o /boot/initrd.img-2.6.28.2rakesh

and added the same into /boot/grub/menu.lst under

kernel vmlinuz-2.6.28.2.rakesh
initrd /boot/initrd.img-2.6.28.2rakesh

error after executing rebooting:

/sys/block/sda/dev : no directory
