I have Kubuntu 12.04 installed on a Dell Studio 1537 laptop, which is prone to occasionally overheating and turning itself off. This has happened a few times before, but without consequence. Yesterday, this happened and I haven't been able to boot since. Some updates were being installed at the time of the crash.
The GRUB menu appears as normal, but none of the options (normal or recovery, or any of the kernels listed) will boot. The dots on the boot screen continue to move indefinitely (I've left it booting for over an hour) but the hard disk access light turns off after a short while and nothing else seems to happen. The system will then not respond to anything except turning the power off. I have a Windows dual boot which works normally, and a bootable Tinycore usb stick. I don't have a live CD, but I can make one if necessary. The following debugs are from attempting to boot in recovery mode (kernel 3.2.0-27-generic):-
Distribution: Ubuntu 12.04 LTS, Kubuntu 12.04 LTS, Scientific Linux 6.3

Rep:
Once you get this problem straightened out, I would urge you to get to the bottom of your laptop overheating. I have a Toshiba laptop, and I had the same problem with it randomly turning itself off due to overheating. In the end, I had to take it apart, reseat the heat sink with new thermal past and generally clean it out. That seems to have solved the problem. I'm not suggesting that you take apart your laptop, but maybe it is worth getting it serviced. It should not be overheating.
The OP indicated the recovery option doesn't work. If Tinycore has a current fsck.ext3 that would be my first priority, else get a liveCD that does.
I concur on cleaning the laptop - I have a 1645 (a 2+ year old i7) and it requires the back taken off it and washed (yep, washed) twice a year. The venting is ridiculously small, and easily clogged by dust here. I also clean the fan each time.
No had it shutdown on me.
I have managed to get it fixed with the help of a live CD. I have taken my laptop apart and tried to clean it before, although this seems to make little difference. Overheating tends not to happen if I remember to prop it a few centimetres above the surface of a desk with books though.
