Hi, I have a problem when installing *.vdi on windows 7 64 bit (server PC HP xw8400). I've tried to add & remove the RAM, re-install the OS, and re-install the virtualbox, yet it always showing an error. In other case, when I try to install it on Linux (Kali linux on laptop) and on Windows 7 64 bit (ordinary PC/non server) it didn't error and works well. Here I attached the log file. Anyone can help me, thank you in advance.

You don't "install a VDI". A VDI is part of a VM, and if you have a working VM then the procedure for moving it is described here: viewtopic.php?f=35&t=55003.

What is the guest OS?

Maybe this will shed some light on the problem https://www.virtualbox.org/ticket/11810
