Virtualizing Windows XP on disk to VirtualBox

(no success so far, still a black screen :/)

For 16 GB : begin at 22h27 of dd, end at 22h38 (apparently I've got 50 MB I/O throughput which should take me approximately 5 minutes to end up, or rather 10 minutes if I/O include read/writes : 16 GB * 1024 / 50 MB/s / 60 seconds * 2 to get the result in minutes )
ok confirmed :

At approximately 70 MB writing on disk, it should end up in 5 min (well, yes it took 5 min :D)

VBoxManage convertdd vmwin.dd vmwin.vdi
Converting from raw image file="vmwin.dd" to file="vmwin.vdi"...
Creating dynamic image with size 17708995584 bytes (16889MB)...

first boot of VM newly created using vmwin.vdi results only in a black screen and 1 CPU running at 100% till stopping the VM :/ some possible reasons : boot.ini configured with the parameter /burnmemory = 4096, the RAM is reduced to 4 GB (reduces the RAM another 4 GB, which leaves the virtual machine with 0 GB of RAM o_O) migration with VMware, driver lsilogic vs ide...

Seem the option for VBoxManage has changed:
VBoxManage convertfromraw vmwin.dd vmwin.vdi

reasons for black screen of death when migrating windows xp to VirtualBox
looking for the reason why I've got a black screen, cursor blinking when first booting windows migrated to VirtualBox

apparently not related due to upgrade due to guest additions due to upgrade blue screen when moving VM

intelppm.sys virtualbox There are a few Windows device drivers that does not play nice on VirtualBox' hardware. A similar problem may exist with intelppm.sys, which can also cause a hang of the guest OS.

Trying yet another time

Some objectives:
md5sum vmwin.*
2e795421f05f0140be240182c7e39551  vmwin.dd
066303a8b37a2a178f378413741d838d  vmwin.vdi

I made a backup to my USB drive, formatted as ext4 (better for files 12 GiB large... than fat32)
df -h .
Sys. fich.     Taille Util. Dispo Uti% Monté sur
/dev/sda7         50G   44G  4,1G  92% /media/data1

hmmm I won't be able to work on this, copying on another laptop ;-)
