Answer 2

Answer:

A bootable device is a kind of storage hardware, such as hard drive, USB flash drive floppy disk drive, DVD, CD-ROM drive, which contains necessary boot files and drivers for loading the operating system. BIOS is a program in computers used to load the operating system and execute the boot operation. The “no bootable device found” error is actually reported by BIOS. It means BIOS cannot find or locate the boot device or the boot files on the boot device are incorrect.

Explanation:

• A computer cannot ‘boot’ if it does not have the Operating System.
• An operating system is system software which handles software and hardware resources and gives services to computer programs. The computer system requires an operating system for “boot”.
• A Loader in the computer systems is a unit of the operating system which is primarily responsible for loading the libraries and programs.
• An assembler in the computer system is a program which interprets software programs written using “assembly language” into “machine language”.
• when a computer powers on and starts up, its BIOS and CMOS will check the system setup, hard drives, and then boot the operating system. If something goes wrong during the process, the operating system won’t be launched successfully. Besides the physical damage of hard drive, the following causes can also make your Windows not to load successfully:
• The hard drive’s system partition is damaged.
• Computer hard disk MBR information is not right.
• The operating system’s files and folders are damaged.
• The system BIOS does not support the hard drive.
• Multiple hard drives have been connected to your computer, then the computer cannot detect which one is the primary hard drive containing the operating system & system applications.
• Some bad sectors on the system hard drive.
