Hi,

My Windows Vista OS is on Partition 1 (with Boot flag ON) and I am trying to boot it using RAW partition access
My partition tables entries are as shown below. I provided explicit access to partition 1 and created an mbr MyWindows.mbr

I followed this excellent tutorial http://forums.virtualbox.org/viewtopic.php?t=9697 to create VMDK for Windows Vista.

But when I create VMDK using this command
"VBoxManage internalcommands createrawvmdk -filename rawDiskXP.vmdk -rawdisk /dev/sda -partitions 1 -relative -mbr MyWindows.mbr"
VMDK created shows me full size harddisk of 300GB whereas it should have been only 131 GB.
If I try to boot Windows VISTA it throws me an 0Xc000000e Error. I understand the error and it is because of hard disk partition not being detected properly.

Please HELP me understand how to get past this error.

You have specified the whole disk instead of just the partition...
In case that the windows partition is the first one, try with: /dev/sda1

Hope this helps...
