DasBoot Quick Start Guide

What is DasBoot?

Do you have a shiny new music player in your pocket? Or perhaps you have a flash drive or small portable hard drive? Now you can turn it into a Mac OS X diagnostic, repair, and maintenance tool. DasBoot allows you to take any third party boot CD/DVD (such as those shipped by SubRosaSoft.com Inc, Prosoft Engineering Inc, Alsoft Inc, or Micromat Inc) and quickly create a bootable diagnostic device that contains all of the utilities you may wish to install.

You can make your music player boot and repair Mac OS X computers without erasing it, or taking away your ability to play music. With the help of DasBoot you get to carry all the tools you’ll need with you. But unlike expensive third party alternatives, you’ll have plenty of space left over in case you need to recover data, or want to keep playing music.

DasBoot devices run software much faster than a CD/DVD repair disk. In addition, you can re-configure the device at any time to add new utilities, updated versions of software or newer versions of Mac OS X.

DasBoot has been tested with the following disk utilities and data recovery tools, but will also run many others: CopyCatX, FileSalvage, MacForensicsLab, VolumeWorks, Drive Genius, Data Rescue, DiskWarrior, and TechTool Pro.

Users of DasBoot must have purchased licenses to install the various disk utilities, and own an appropriate disk utility bootable CD/DVD to use as the source disk.

System Requirements

DasBoot is programmed to run on the following minimum specification:

  • Apple Intel Mac
  • Mac OS X 10.5 to 10.6
  • DVD-Rom drive for Boot CD/DVD
  • Bootable CD/DVD from 3rd party (The Mac OS X installer disc will not work)
  • Bootable device (FireWire drives, iPods, USB Flash drives, etc…) iPod Touch, iPhone, iPad, and iPod Shuffle are not supported.

Running DasBoot

Launching DasBoot

Once the DasBoot application is in the Applications folder, double-click the file icon to activate the software. The user will first be greeted with the DasBoot splash screen.


After a couple of seconds, the splash screen will close and the user will be presented with the screen below. Click on the SubRosaSoft.com Inc button if you would like to find out more information about the company’s other exciting software products. To continue to work with DasBoot, click Start and the main screen will appear.

The program will prompt you to enter your administrator password. This allows DasBoot to use the full power of the Mac OS X operating system. If you don’t have a bootable CD or DVD inserted into your CD/DVD drive, DasBoot will automatically request that you insert one to be used as the source disk.

Insert a Boot CD or DVD

Once a bootable CD is inserted, the main window will be updated immediately. Information about the bootable CD/DVD will be displayed on the source panel, while the destination panel will be populated with all volumes (other than the startup drive) formatted with HFS Plus.

Using DasBoot to Create Bootable Devices

From the Source Panel, you can select a source CD or DVD from the popup menu. The source disc must be a bootable CD/DVD that you have purchased from a disk utility such as those shipped by SubRosaSoft.com Inc, Prosoft Engineering Inc, Alsoft Inc, or Micromat Inc.

The destination panel will display all volumes (other than the startup drive) formatted with HFS Plus.

Quick Tip: Booting Off USB Devices
USB devices can only be used to startup Intel-based Macintoshes. For PowerMac, you will need to use FireWire based devices (such as earlier generations of iPods, FireWire based flash drives, or standard FireWire hard drives) as your startup drive.

DasBoot will automatically detect many applications that can be added to the bootable device. In addition, you can select the applications you would like to include on your bootable disk. Simply drag and drop the application of your choice into the list below to add it.

To ensure the correct operation of each application, you should first install it into the computer’s Applications folder (do not drag directly from an installer CD).

Installing Apps

You can select the default language on the bootable device you plan to build with DasBoot. By selecting from the Language popup menu, you can set the language to US English (the default), Japanese (日本語), or German (Deutsch).

Language Selections

To continue building the DasBoot device, click Start the DasBoot Process.
A warning dialog will inform the user that the process is irreversible.

Can't be undone

If you run Mac OS X 10.6 and create a DasBoot device based on a third party Mac OS X 10.5 DVD, many Apple utilities will NOT work since they are not backwards compatible. For example, Disk Utility from Mac OS X 10.6 will not run under 10.5.
The microdrives found in many digital music players and portable storage devices are not designed for extended use. Using these devices for long periods can cause them to overheat and may void the warranty on the devices.

The microdrive is usually the most fragile component of a digital music player (such as the first and second generations of the iPod Mini). If the device is out of warranty it can be very difficult to replace the drive.

The user can click Cancel to stop the process, or click OK to proceed with the operation. Clicking OK will bring a progress box to the foreground at the top of the window. This provides the user with live updated information on the progress of the DasBoot creation process.

In Progress

When completed the user will be presented with a final dialog box confirming the completion of the copying process. The user should close this by clicking on OK, at which point he or she can begin using the DasBoot device as a bootable diagnostic, repair, or data recovery tool.

Appendix: Questions & Answers

Can DasBoot work with iPods formatted for Windows machines?

No. DasBoot will only work with Macintosh formatted iPods.


I have been successful starting my Intel-based laptop with an iPod startup disk made using DasBoot and a Universal startup CD for DiskWarrior. While the CD can startup a PowerPC based PowerBook, the iPod doesn’t work on that system. Am I missing something?

USB iPods will not boot non-Intel-based Macs. You will need an iPod with FireWire connection to boot the PowerPC based machines.

Can I use the OS X installer CD/DVD as the source disc?

No. Only third party bootable CD/DVD discs such as SubRosaSoft’s FileSalvage, CopyCatX, VolumeWorks; Alsoft’s DiskWarrior; Prosoft Engineering’s Data Rescue II and Drive Genius will work. For a forensically sound bootable device, use MacForensicsLab Inc.’s MacForensicsLab (MacForensicsLab.com) as the source disc.

I have a 17” MacBook Pro and I am trying to use my first generation iPod Mini as a DasBoot startup device. However, it doesn’t show up on the Startup Manager screen (holding down the <option> key during startup). Suggestion?

We have experienced a situation when microdrive based iPod Mini connected via USB to a 17” MacBookPro failed to appear on the Startup Manager screen. However, switching the connection to FireWire solved the problem.

Tried using DasBoot with my Diskwarrior CD to a FireWire drive. The copying process counted up to some 9800 files, then just sat there doing nothing. What gives?

  1. Reformat your external drive and try again.
  2. Check your CD/DVD. Can you use Disk Utility to clone the CD/DVD to a disc image? If not, The CD/DVD may be a problem.

I connect a brand new USB thumb drive to my MacBookPro, insert a bootable CD into the CD drive, and launch DasBoot. The CD shows up OK, but nothing shows up as destination. What gives?

The thumb drive is probably formatted on a PC and DasBoot will filter any non-HFS Plus partition from showing up in the destination window. You will need to reformat the thumb drive to work with DasBoot.

I used DasBoot to make my iPod into a bootable trouble-shooter. As a source disk I used the TechTool Deluxe CD that came with my AppleCare Protection Plan. When I tried the DasBoot device on my Mac, the iPod spins down and nothing happens.

If possible, check the CD to see if it’s bootable on the system you were running the DasBoot device on. In some cases, it will begin to boot but not go through the whole process. You may want to try another CD that has no problem booting all the way to the application.

DasBoot cannot see my iPod, but iTunes has no problem detecting it. What happened?

The iPod has to be formatted with HFS Plus, and it has to be running in Disk Use mode, else it will not show up as a destination.

I’ve added an application not on the list of supported applications and it won’t run. What should I do?

Some disk utilities will require the user to copy additional components in order for the utilities to function properly. For example, older versions of SubRosaSoft’s disk utilitiessuch as FileSalvage, CopyCatX, Prosoft’s Drive Genius, and etc… install a couple of application support folders into the Library folders of the drive and home directory. You may need to manually copy those folders over to your DasBoot device if your software fails to run properly under DasBoot.

How do I enable Disk Use mode?

To enable Disk Use mode, follow these steps:

  1. Connect the iPod to your computer while holding down the Option and Command keys to prevent iTunes from automatically syncing with the iPod.
  2. Open iTunes and select the iPod in the source list.
  3. Click the Summary tab.
  4. Select the option to “Enable disk use”.
  5. Click Apply.

 I would like to make an archive copy of the DasBoot device. What application should I use?

The fastest software duplication system for Mac OS X, CopyCatX from SubRosaSoft.com will make a perfect image of your DasBoot device.
