In older versions comes up an error message when installing Windows 8 or 8.1 in the virtual environment, because the following SET options have incorrect settings:
Set the video memory from 16 MB to 64 MB
Set the memory (RAM) to 1024 MB
Use hard drive
VDI and not VHD.
And the operating system version: "Other Windows"!
PS: With VHD, it was always at 96% or 97% error and "Error code: 0x8007045D". The hard disk should be best set to 60 GB.
