Lenovo Notebook V470 Installation Win8.1 X64-bit system, shutdown black screen, power LED light

The previous WIN7 X86 system used for a long time, the software industry installed a lot, now use a bit of cards, and recently decided to reinstall a system, the background found that there is a thing to develop the WIN8 X64 bit, download a ready to install directly, and since then began a full 2 days of tangled

Issue 1: Lazy ready to install with WIN7 hard drive, failed

The prompt partition is not supported by the active partition, so think about converting to basic partition, using the DiskPart command, after installing win 8.1

Issue 2: Use win 8.1 X64 to partition with partition, after installing the system, shut down the crash BUG

Install the system, in a step restart the computer when the crash, I forcibly shut down, restart continue to install, know completely installed into the system, resolution and other problems is the system driver did not install, as long as the installation update can, WIN8 from the driver installed, but found as long as a shutdown on the crash, Back and forth Drive Uninstall install new, completely invalid. start to suspect that the WIN8.1 system is a problem, or incompatible with the cause, I will change back to WIN7 it

Issue 3: Reload WIN7 X64 found, also is the shutdown crash bug

X64 words I use is Burning disc installed, so do not use mode 1 to solve the problem, change the X86 I do not know not to try,
