I have several problems with my ubuntu 12.04, which I think interrelated. My first problem is that recently my kernel got updated to 3.2.0-29 (I'm not sure whether it was just generic or generic-pae). Since then my virtual box was not loading displaying an error code Kernel driver not installed (rc=-1908). So, I tried many work arounds, suggested in several threads with no use. I tried to remove, reinstall virtualbox from different sources, no use. When I looked at my synaptic and found that old kernels to be present (3.2.0-27 & 26). In the event of removing them, thinking that they may be causing problem with virtualbox, I accidentally removed my all the kernels, so I couldnot boot. Hence I followed method adviced in this thread How to restore a system after accidentally removing all kernels? (detail method). I didn't know which kernel to install. As my pc has more than 3gb ram, i used generic-pae.
So now when I boot my computer everytime, I'm prompted to grub2 loader menu asking which kernel to use. But I have only one kernel. It also asks whether I should repair kernel (but repair doesnot work, it displays same menu again). I updated grub, but no use. I want to your help on this. I want my laptop to boot & load automatically.
Second is if I run virtual box it displays same error code, described earlier. If I run sudo modprobe vboxdrv the problem gets solved for this boot. But when I reboot, same problem with virtual box.
I greatly appreciate your assistance on this.
Thanks in advance
