I am attempting to install Windows Vista Ultimate 64-bit in VirtualBox, however I am encountering a problem that halts the Windows installation program from even executing; briefly described as follows:
< Windows Boot Manager >
Windows failed to start. A recent hardware or software change might be the cause ...
Info: Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode.
I have conducted a wide variety of Google searches to invest a fix for this particular problem; resulting in only bits-and-pieces of information which don't explain "fully" how to resolve this problem. From what I have read, all I know is I somehow need to enable "VT-x/AMD-V" in the BIOS. However, what never seems to be clarified is whether this is referring to the BIOS of the virtual machine, or the BIOS of my actual, physical notebook PC. And if it is the BIOS of the virtual machine, then how do I enable "VT-x/AMD-V" or even access the BIOS of the virtual machine?
I would greatly appreciate some simple, straight forward assistance in this matter as quickly as possible.
