I need to boot my MacBook from an external disk so I can repartition the internal HD using iPartition. I was thinking about using a USB-C flash drive for that.
Can someone tell me how I can create such a beast (preferably with iPartition added to it so I can actually run it).
iMac, OS X Yosemite (10.10.5), Core i7, 27"
You could just install OS X on to an external drive. Then you can boot from it and use Disk Utility. The need or use of iPartition is not required.

I need iPartition because I need to resize the existing partition (without losing its content) to make room for a new one.
And how do I create a bootable external drive with Yosemite? I don't have the Install OS X from that release.
Disk Utility can resize an existing partition without losing its contents.
If you previously downloaded the Yosemite installer, it should be available from the Purchases tab of the App Store app.
Have you looked at the free SuperDuper which creates bootable backups?
Lanny, how fast is Disk Utility on such a task and how energy-intensive is it? I want to boot a MacBook (USB-C) from a bootable flash drive connected to the USB-C port (so it cannot be charging at the same time, as there is only one port on the MacBook) and any manipulation I then do on the internal disk has to be finished before the battery is empty (with a safety margin to spare).
