DiskWarrior now ships on a flash drive instead of DVD. If you plan to rebuild the directory of your startup disk, you need to start up from another disk capable of starting up in Mac OS X 10.5.8 Leopard through macOS 10.15 Catalina, such as the DiskWarrior Recovery flash drive or your Mac's OS X Recovery (the Recovery HD). OS X Recovery is available in OS X 10.7 Lion and later.

Whether started from the DiskWarrior Recovery flash drive, OS X Recovery or another disk, DiskWarrior can run from the flash drive to eliminate all damage to any HFS (Mac OS Standard) and HFS Plus (Mac OS Extended) disk directories, including your normal startup disk.

Click here for step-by-step instructions on starting up from the DiskWarrior Recovery flash drive or OS X Recovery.

The DiskWarrior Recovery flash drive ships with the ability to start up any 64-Bit Intel Mac that currently starts up in Mac OS X 10.4 Tiger, 10.5 Leopard or 10.6 Snow Leopard. If you have a newer Intel Mac, you can use the included DiskWarrior Recovery Maker to update the DiskWarrior Recovery flash drive to start up your newer Mac.

A green DiskWarrior Recovery disk icon indicates that the DiskWarrior flash drive contains the DiskWarrior Recovery as it shipped from Alsoft. This disk can boot any 64-Bit Intel Mac that currently starts up in Mac OS X 10.4 (Tiger), 10.5 (Leopard) or 10.6 (Snow Leopard).

If you have a newer Mac that currently starts up in OS X 10.7 (Lion) or later, you will need to update the DiskWarrior flash drive with the included DiskWarrior Recovery Maker. A DiskWarrior Recovery flash drive updated with DiskWarrior Recovery Maker will have a blue disk icon as shown below. Alternatively, you can start up from your Mac's built-in macOS Recovery.

3) Use the left and right arrow keys on the keyboard to select the DiskWarrior Recovery disk and then press the Return key.
