I tried converting my PC using disk2vhd
several times with no success. I check all partitions including hidden system partitions and create single .vhd
file from it. I did it before with Windows XP and Windows 7 and both boots in Virtual Box without problems.
For Windows 8.1 I always get No bootable medium found
when trying to boot the VHD.
Are there any special steps to take in either creating VHD or attaching it to VirtualBox to make the system boot? I need it for an emergency backup before I wipe up the system and upgrade to Windows 10.
