Against better judgement, I allowed my 14z to install W10. It performed like a dog, but worked OK. However Office 10 was unusably slow, possibly because I was running a 32-bit version. My troubles really began when I tried to uninstall Office. First W10 wouldn't reboot on restart. I tried to run the recovery disk from my initial installation of W8, but this crashed with a disk error. I ran full diagnostics, including disk partitions, which were all fine. On reboot, it failed - I just get beeping after about 20 seconds. I have repeatedly tried to restart holding the F12 key but it just doesn't activate. Same with the F2 key for set up. It just will not go into a boot sequence or access the BIOS. Lights are flashing and Disks are whirring, but I just get the beeping starting up after about 20 seconds.
How can I break in? My Ultrabook is only 2 years old and I cant afford a new one!
