HP Pavilion M6 1025 have problem with random blue screens. Please help.

Hi everybody, I have a strange problem. For about 3 months my notebook Pavilion M6 have problems with blue screens. The show on diffrent time -randomly and then after reboot to laptop generates an error that no boot media is installed (hard disk failure?), but some minutes later he boot's normal. I've got such problem before and hp on warranty replaced my hard disk and it was for some time OK. I don't bealive, that the hard disk is again broken. Currently I'm working on windows 8 and here comes the blue screens - the older disk works with windows 7 and no bluescreens appear - "only no boot media problem". I'm working on Ubuntu 14.04 too and there are no problems with crashes or other weard behaviours - so i think it's not a hardware issue. Could somebody help me with my problem?
