I have three linux images (kernels) installed.
3.0.0.17.30 generic
3.0.0.16.29 generic
3.0.0.12.20 generic

I can boot into other kernel versions with no problem, but when Im trying to go into 3.0.0.17.30 generic, a red screen appears and then nothing happens. it just got stuck there. No HDD activities. Nothing.

What should I do ? I have updated some files today. May be its causing that. I can not delete 3.0.0.17.30 as when Im trying to delete through Synaptic it shows I will be removing

3.0.0.17.30 generic
