I did a horrible misstake. Please help! (kernel-upgrade)

Hi!
Today i got message from YOU about new kernel.

I run the upgrade and minimized the YOU to tray. Then i really forgot about this and did a shutdown for adding more memory. So what happens is that i break off the kernel-upgrade and now it refuse to start up as normal.

It boot up to cli and KDE refuse to start because there is no graphic-driver that work. So i try to install the Nvidia (v185.13 Beta) but it refuse to complete compiling new driver-module becaust there is no kernel-source for the new kernel. I check and i only see the olde kernel-source.
Then i boot up in the old kernel, but i still have to reinstall Nvidia-driver. Now it goes a little more, but then it says it can’t load the nvidia.ko and this maybe is because the driver is compiled in the wrong version of the kernel.
I also can’t re-run the YOU because i have no network. I try to start network but only “lo” is awailable. There is no eth0 or wlan0. Maybe there is some driver-issues.

So is there any way to fix this?

You can boot the install dvd to repair that. Did you use the dvd?

No i didnt try to boot from dvd! How do i repair from dvd?

Boot as for Installation
Then at this screen: Installation/11.1 DVD Install - openSUSE
Choose Repair Installed system
Choose expert repair when asked and go to software packages. You need to lockdown the entire system of packages except the kernel packages (kernel, kernel-base, kernel-extra)
Accept

P.S. Make sure it doesn’t change your bootloader settings
