one, problems with installing a 64-bit system in a virtual machine on a 32-bit system using VirtualBox

This machine is a 32-bit Win7 system, want to install 64-bit window server2008 64-bit system above, the result is not supported by CPU, prompt "Attempting to load a 64-bit application, however this CPU I s not compatible with 64-bit mode. " This error.

    But Baidu query its own CPU model, found that the model from the hardware support 64-bit system, then why the virtual machine can not be installed in the 64-bit system. The reason may be that the vt-d parameter in the system is not set, the default is disabled, you need to manually change to Enabled, which is the hardware virtual machine technology.
    Enter the system's BIOS settings, press F2 in the boot when you can enter, and then through the location to find the settings, modify it, the last F4 save changes to restart the computer is OK, of course, different brands of the computer into the set BIOS interface different, set the shortcut keys are different, Here you can find a similar location to set it up. Reboot and then continue installing window server2008 64-bit system, sure enough, passed.

Make sure there are enough free space on the disk and that the disk is working properly. Operation can be resumed afterwards. " This error.
    When I set the disk size of the virtual machine system, I set the first time to 10G, prompted in this error, I look at the disk space is too small, and then I reset the system size, set to 50G, resulting in the second installation process to copy files to 60% The appearance or the hint disk space is not enough, this let me tangled up, why? By finding the data found, is my disk format is not correct, I stored the virtual machine system of the format of the letter FAT32, the format of the maximum support 4G files. So when the file grows more than 4G during the installation, there is a problem.
    I want to add a disk, through computer-management-Disk Management--add a, need to format, and then convert. OK
