I can't boot anymore!

["Axel Gallus" <uh5d@rz.uni-karlsruhe.de>]

Yesterday, i have resized my debian partition with partition magic from
windows.
After that, i was not able to boot from that debian partition - what happens
is that
it displays "GRUB" and the system halts.

So i made a netinstall cd (ca.180MB http://www.debian.org/CD/netinst/) and
tried a
"rescue root=/dev/hda2" , but it says it can not find a kernel called
rescue.

Then i tried a "linux26 root=/dev/hda2" , and it says "unable to mount root
fs on unknown-block(0,0)".


So, how can i restore my system?
