Migrating from Parallels Desktop to VirtualBox

Posted by

If you’re upgrading to Mavericks and don’t want to have to pay for a new Parallels version then you can use the free VirtualBox.

In this scenario I’m going from Parallels 4.0 to Virtual Box 4.3.10. If you are migrating from a later version of Parallels you might be able to skip the first 7 steps.

  1. In the Parallels folder open Parallels Transporter
  2. Click Continue
  3. Select Express
  4. Select Virtual Machine
  5. Select Virtual Disk
  6. Choose your Parallels virtual machine
  7. Click Migrate
  8. Wait about an hour
  9. Find the .pvm file for your converted virtual machine.
  10. Right click and select ‘Show package contents’
  11. Right click on the .hdd file and select ‘Show package contents’
  12. Copy the .hds file to somewhere else
  13. Rename the .hds file to .hdd
  14. Open VirtualBox
  15. Create a new Virtual Machine with the .hdd file from above as the virtual disk.
  16. Run your virtual machine!

Problem creating partition with Diskpart for OS X install

Posted by

When preparing your hard drive for an OS X 86 install you will generally need to create an active partition with an id=af using the commands below.

list disk
select disk x [x is the number of the disk where you want to install your leopard on it]
list partition [Now diskpart should tell you there’s no partition on the disk, if it show up a partition go ahead and type delete partition]
create partition primary id=af
active
exit

Unfortunately sometimes when you reach the line “create partition primary id=af” you may hit a snag when diskpart brings up an error message stating “the arguements specified for this command are not valid”.

To fix this, you need to go the disk management facility in windows (right click my computer – manage) then storage. Select the disk and right click it, it should now offer you an option to “Convert to MBR disk”. This is instead of GPT. Select this and retry the create partition command. The partition should now successfully create!
