So, after so many shutdowns, restarts and hard shuts I am forced to post a question here. I am sorry if I am wrong anywhere because I am totally frustrated by my laptop and Windows.
I have had an old Acer Extensa 4630 and recently got an HP ProBook 445 G1. I already have Windows 8 Enterprise and Ubuntu 13.10 installed on my old laptop. For easily moving my working environment I cloned the hard disk of my old laptop to my new laptop.
The Acer one didn't have hardware virtualization but the HP one does have VT-x. But whenever I tried to open VS2012 Express for Windows Phone, I failed to restart my computer and/or to hibernate/sleep/shutdown and it gets stuck at "five dots".
At first I thought it was a driver problem, so I tried everything from installing drivers to uninstalling multiple softwares and booting into safe mode. But then after innumerable attempts, I reset BIOS settings and then Windows finally booted. Then I tried disabling Hyper-V and re-enabled virtualization and it booted! But then again after enabling Hyper-V, it failed to boot. At last I understood that either the hardware virtualization or the Hyper-V needs to be disabled to Windows to load.
Every time I try to enable Hyper-V and h/w virtualization together, Windows gets stuck at the rotating five dots.
But I want to know why and I need a solution as I don't want to re-install Windows
Please help me out as I have already wasted my whole week doing system restores, cloning, installing and uninstalling.
UPDATE: I wasn't able to solve the problem, so I gave up. But Windows 10 seems to have no problem, so if you can, update to Windows 10 or get a different laptop.
