Create virtual disk for VirtualBox (VB)
– Manual, default at C:\Program Files\Sun\VirtualBox\doc, section 9.10 Using a raw host hard disk from a guest
– list all drive to ensure it drivename, e.g. PhysicalDrive[#|0,1,2,3]

– create rawdisk, e.g linuxhost.vmdk, winxp.vmdk…. , mkdir first if required.
(for me, I need to create all 4 drives, don’t know why, I expected only 0,3)

RAW host disk access VMDK file c:\Users\{YourUsername}\.VirtualBox\HardDisks\linux.vmdk created successfully.
– Run VB as administrator (this make me confuse too, I am power user…yet, UAC isn’t turn off)
– Virtual Manager > add those created virutal disk files (*.vmdk)
– create a new virtual machine
System: uncheck “Enable IO APIC”
Harddisk:
Enable additional controller: SCSI (LsiLogic)

N.B. : only add winxp.vmdk & linux.vmdk, blank screen with (00:00:03.291 Guest Log: BIOS: Booting from Hard Disk…) on VB log (right click VM, show log..)
– turn on VM, with 4 drives, now got GRUB 21 error.
good, at least it got the disk now….
– download Super GRUB disk, mount it as CD-ROM
follow this link:
http://www.supergrubdisk.org/w/index.php5?title=Howto_Boot_Linux_only
unmount, reboot, RORA !
– one more thing, install linux Guest Additions, manual section 4.3
sudo sh ./VBoxLinuxAdditions-amd64.run
