We are trying to virtualize an old Windows NT 4.0 server in a bad shape. We've managed to create an vmdk image using vmware converter coldclone boot cd and we can successfully run it on vmware workstation which works flawlessly but we want to migrate it to Virtualbox.
When the VM is created as IDE or SATA controller it loads up to a point and then gets stuck on blue screen STOP: 0x0000007B INNACESSIBLE_BOOT_DEVICE and loads of text about .sys files.
If we change the controller to SCSI or SAS it just gives us a black screen "Missing Operating System" We've tried switch on/off IO APIC and Enable VT-x/AMD-v also switched between lsilogic and buslogic Always getting the same results.
Any help will be highly appreciated, many thanks in advance! :-)
