Abstract: In example implementations, a computing device is provided. The computing device includes abasic input/output system (BIOS), a first storage device to store a first operating system (OS), a second storage device to store an alternate OS that is accessible by the BIOS, a volatile memory, and a processor. The processor is in communication with the BIOS, the first storage device, the second storage device, and the volatile memory. In response to a determination that the first OS is unavailable, the processor is to cause the IOS to load the alternate OS from the second storage device into the volatile memory, disable access to the first storage device, and cause the BIOS to execute the alternate OS from the volatile memory.
