It’s pretty simple: a small tool and 15 minutes of work
I had to help a user in the migration from an old laptop (with serious motherboard issues) to a new laptop.
The old PC was equipped with Windows XP, it contains almost 6 years of data and some old copies of licensed software (with an old version of Lotus Notes) of which had been lost licenses and install media.
Data and software migration was so difficult: the old laptop stops responding when the CPU temperature exceeded 20 degree.
So i choose a virtualization solution: I open the laptop, i pull out the hard drive and i mount it in a SATA-USB box.
The goal: create an image of the physical disk to use in a virtual machine to run from VirtualBox in the new computer.
With only a Windows PC , without downloading a live distro of Linux I decided to use an official Microsoft tool.
The tool is Disk2vhd , and allows you to create a disk image from a physical disk (or from a running machine): the image format is VHD (Virtual Hard Disk — Microsoft’s Virtual Machine disk format) which fortunately is fully supported by VirtualBox.
The use is very simple: just start the utility, select the disk you want to import and choose the directory in which to save the image. The procedure is also quite fast: a 60GB disk was imported in less than 15 minutes.
Once the image is created, I created a new virtual machine and, when choosing whether to create a new disk or use an existing one, I chose the second option and specify the path of the file just created.
To avoid boot errors caused by the change of hardware, I made a few small changes to the configuration: in the System section I modified the chipset tp ICH9 and enabled IO PIC.
After starting the virtual machine, I installed the VirtualBox Guest Additions and created a shortcut on the desktop to start the emulated machine.
