Dual Boot USB installation with OSX and Windows I have a 16gb USB pendrive that I want to partition to be able to use it as a Window 7 and Mac OSX install drive (probably using a bootloader?!?) 

I want to be able to use it on our Macs and PCs as a single all-singing all-dancing install drive.

Can anyone point me in the right direction to a guide to do this? is it even possible? I have both Windows and Mac machines at my disposal.
I just bought three 8 GB thumb drives to use as OS X, Linux, and Windows 7 installers.

I suppose you could split the thumb drive into two 8 GB partitions and create two installers.  Whether or not both are visible on Macs and PCs is unknown.  I suppose it will depend on the hardware.

To create the OS X installer, you need only run the following from Terminal.app.  Note the partition name, I used "Untitled" for the script below.


  /Applications/Install\ OS\ X\
  Yosemite.app/Contents/Resources/createinstallmedia  --volume
  /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\
  Yosemite.app --nointeraction


To create the Windows installer, you take the Windows installation ISO file on a Mac, go here and scroll down to "Creating a Windows flash drive installer on an OS X computer".
