Error after booting default kernel version

[Gábor Hársfalvi <hgabi84@gmail.com>]

Hi,

I've used this tutorial ->
http://forums.debian.net/viewtopic.php?f=16&t=60019 - yesterday, and
after reboot the playmouth animation worked but before it arrived
login screen it showed me a black blank screen with a flashing cursor
- not mouse - and after more waiting it stayed there too.

I reboot after it and start with a previous kernel version number -
the number ends with 486, not 686 - with Rescue Mode. It started and
after Ctrl+D - when it needs - it booted the gui succesfully and
everything worked well.

I would like to start the computer with the newest available kernel
version number, what ends with 686, and what were the default when I
started the system before, but it doesn't work and give me the error
screen what I mentioned before.

Please give me help to repair this to boot the computer normally as
before it was happenned.

Thanks.
