assuming virtualbox is installed and running,
click new (top left)
click next in the new window
you will need to add the vm name and o/s type from the drop down boxes
click next
add base memory (i use 512 - but this will depend on how much physical memory you have))
click next
create new hard disk
click next + next
check dynamically expanding storage
click next
you need to add the location where you want your vdi - or just leave it at default
and you need to set the maximum size of the virtual disk (i use 20gb)
click next + finish
click finish again
you have now created your virtual hard drive
now click settings
click CD/DVD-rom
check - mount cd/dvd drive
check - iso image file
click the little file icon
click 'add' at the next window and navigate to the .iso
click select
click ok
click start and you should be on your merry way
good luck
