Windows 8.1 preview (64 bit) on VirtualBox

The installation procedure is pleasant and easy. Here is how:

1. download binary and get key from Microsoft here,                                                                                          license key: NTTX3-RV7VB-T7X7F-WQYYY-9Y92F
2. create virtual box VM  (suggested version 4.2.18, which supports 8.1 directly)
3. follow the screen to install.

Windows 8.1 64Bit

There are two catches:

• 0x000000C4 error  & fix  

Root cause:  windows version not match VM;  

Solution:  make sure VM is created for windows 64bit if you are installing 64 bit version.

• Installation abort - space issue.

make sure your VM has at least 2GB RAM, and 8GB of hard disk space
