i have seen this ( cant post link) How to migrate existing Windows installations to VirtualBox
but when i try cat /dev/sdg | VBoxManage convertfromraw stdin OutPutFile.vdi NUMBEROFBYTES
i get this
OutPutFile.vdi NUMBEROFBYTES
Converting from raw image file="stdin" to file="OutPutFile.vdi"...
Creating dynamic image with size 0 bytes (0MB)...
VBoxManage: error: Cannot create the disk image "OutPutFile.vdi": VERR_INVALID_PARAMETER
what am i doing wrong? also if i do get this to work will i still be able to run windows 7 in dual boot as i currently do?
thanks for any help
