virtualbox.org

Hello,
I installed windows 7 ultimate 64bit version some time ago and I installe VBOX version 4.0.2 to run Linux guest (slackware) and xp guest. As I already had a complete and working XP installation on another disk connected to the pc as PhysicalDisk2 I would like to use as boot disk for my XP Vbox VM. I have created the vmdk image using

VBoxManage internalcommands createrawvmdk -filename c:\dwl\winxp.vmdk -rawdisk \\.\PhysicalDisk2

and I got the file winxp.vmdk. Then I created the XP VM pointing to that file as disk image. Unofrtunately when I start XP VM the system start to boot, I can see the first XP splash screen but after a while I got a BSOD saying: UNMOUNTABLE_BOOT_VOLUME.
I tried to give full access to all disk structure (I can access that drive under W7 as E:) with no result. I give full access right to me, administrator, everyone, creator owner... nothing change. BSOD and continuously reboot. I had a look to the Vbox logfile reading some entries like these:

00:00:03.774 Display::handleDisplayResize(): uScreenId = 0, pvVRAM=0000000008f00000 w=640 h=480 bpp=0 cbLine=0x140, flags=0x1

So I guess I have some issue concerning with disk access rights, but I am unable to understand how to give the requested access privilege to Vbox. Does anyone have any suggestion to help me ?
Thank you in advance for your help.
