Creating a bootable medium - O&O DiskImage ToGo
O&O DiskImage ToGo function automatically turns an external hard drive that you select to store an image on (or USB flash drive with enough storage space) into an O&O DiskImage boot medium, and marks this disk as the preferred storage medium for future system backups. As soon as you connect this external USB hard disk to your computer, O&O DiskImage automatically creates an image of all internal drives and the data partition onto it.
This makes it easy to create a recent backup. And, if something really happens to your computer or you want to transfer your system and all your data to a new computer, then with the O&O DiskImage boot medium you can restore the image stored on it with just one touch of a button, without the hassle of searching for the boot medium and the external hard drive with the backup.
Creating a bootable disk with O&O DiskImage is possible by going to the menu item Tools -> Create bootable disk. This feature detects those options available for creating a bootable disk within the system. It will then copy all the files that are required for doing this. To begin the process, click Create. Once this step is successfully completed, click Finish.
