Brand new Dell XPS 13 Ultrabook with Windows 8. 256 SSD, 8 gigs of memory, i5-3317, non touch screen. Working fine for 2 months and now will not boot after Dell logo. Have been on tech support three times still not solved. They sent a USB recovery drive and does not boot. They sent an optical drive and the windows recovery disc; still not working! Not a novice at this but fully stumped. Cannot get to a C prompt, cannot get into Safe mode. Am able to get into BIOS but is limited in what can be done there. Diagnostics says everything is fine. Am ready to go back to Windows 7 until they work the bugs out. Please help and thanks in advance.
