A tape drive operates as a bootable device for a PC. In a first mode, the drive operates as a normal tape drive. In a second mode, the drive emulates a bootable CD-ROM drive. Application software for backing up and restoring computer system data causes the PC running the software to generate a bootable image comprising an operating system including the PC hardware configuration, and data recovery application software. The bootable image can re-build the PC in response to a disaster, such as hard disk corruption or system destruction. The bootable image is stored on tape in front of a file system backup data set. In the second mode, the tape drive boots the PC and restores the operating system and application software. When loaded, the application software switches the tape drive into the first operation mode and restores the file system backup data set to the PC.
