Yes very easily. You create a new VM Disc drive in the Parallels wizard and when you get to the third screen you are given a choice of creating an Express Windows/Typical or Custom drive. Here you choose Custom and click continue. In the next window you choose the amount of RAM and number of CPUs you want to allocate to the VM. Click continue In the next window choose the Bootcamp Partition as your Hard-drive and again click continue In the next window check that the Bootcamp Hard-drive name corresponds with a primary Hard-drive- This is Important ! Click continue Next Window is for setting Shared Networking and Internet Access for the VM - Recommended you leave this as default which is Shared Networking Click continue In the next window choose whether to allow the VM or OSx to have resource priority. Click continue In the next window you give a name to the VM. Below this is a reveal triangle. Click and expand this . You are offered a tick box for a desktop launch icon (If you are a Tidy Mac pedant you will probably want to un-tick this !) For a Bootcamp drive leave the share VM option un-ticked as well You will see a box with the path to the folder where all created VM images are stored (the default is to a new folder in YOUR ~/home/documents folder- But you can change it here if you must). Click create. In Parallels 4 you are now presented with a VM menu with the name you gave earlier. Click the start button or choose Start from the Virtual Machine Menu Bar. If you have set finder to show all Hard drives you should see the Boot camp Windows Partition disappear (Some under the bonnet terminal/unix commands actually find the Windows formatted partition FAT/NTFS and dismounts it from OSx to mount it within the created Parallels VM !) Windows will now boot up and you will have to enter your password as applicable. Eventually your Windows Desktop will load up. (One thing through you MAY find that Windows wants activating again - So a telephone call to Microsoft may be needed in the next three days ) Next you will need to install Parallels Tools (within) Windows to allow a seamless experience and after another reboot of the Windows VM you are now ready to go. Job Done. One other thing you can set in preferences if you want to share folders default applications, drives and security levels between Osx and Windows. If you choose to share folders or the Windows drive with Osx the Windows drive remounts on your Osx Desktop as a shared drive with both READ and WRITE permissions - using the included Mac Fuse application and whether formatted FAT or NTFS ! You may now want to experiment and perhaps try a Linux Distribution or two (for free) within Parallels - Try Ubuntu 8.10 thats nice (the later 9.04 version of Ubuntu has some problems in Parallels 4 - You can't install the Parallels Tools for one and sound is also poorly handled-Just a thought !)
