Grub has its own command line for manually troubleshooting and repairing boot problems, and SGD provides access to this.Īfter detecting operating systems, hit “c” to enter the command prompt. It is not, however, completely without such features. While this is great for keeping the size down, it means that SGD has some room for improvement when it comes to powerful recovery tools. Repairs #Īs noted above, the Super Grub Disk is just a smart Grub installation, not a suite of tools. By simply selecting our detected OS, we can load up Linux or Windows and use whatever repair or recovery tools the OS offers. In this example, we’ve got Windows and Linux installed, but the hard drive’s MBR is broken so we can’t boot either. Choose that option from the main screen and verify that the results are accurate to what you have installed. Bypassing a Broken Bootloader #įirst, you’ll want to make sure it detects all existing operating systems. If it does not boot to SGD, check your systems BIOS settings to make sure the device you want to boot from is higher on the boot order list than your hard drive. Once complete, restart your system with the CD or USB stick inserted. For USB, try the excellent tool Lili USB Creator.

If you wish to boot from USB, the tool UNetBootin should do roughly the same job for USB.įrom Windows, you can find the Burn ISO Image option in your favorite CD burning program or use a free burner app such as Deepburner. The hybrid ISO can handle being installed to a CD or USB device, however CD method is recommended as the burning tools are generally more reliable and easily available.įrom Linux, you can burn the ISO file to CD with just about any CD burning application such as Brasero’s Burn Image option. This image should work on both CD and USB devices.

There are multiple editions available, however I’d recommend that you download the most recent hybrid version available.

You can download the unbelievably small Super Grub Disk ISO file from here. You can use SGD to bypass or repair a broken bootloader, but it can’t recover lost files or run virus scans or other such application-level tasks. This means it can handle all the tasks that a bootloader can handle, namely launching your OS. The Super Grub Disk is essentially a cleverly configured Grub installation on CD.
