The most common bootable device around is the hard drive. That is if its formatted.
So lets say you have a clean hard drive with nothing on it. Well get to your nearest computer and format it and install a new OS on the hard drive.
You dont have to buy expensive ones since there are many free OS like Ubuntu or Fedora etc etc.
all you have to do is format a CD to install the OS image and install it in your hard drive.
Also a CD and a DVD disc can be bootable even a portable USB all you have to do is format them so they can be able to boot.
wow this happens to me alot you have to either press F12 or F11 when it says no bootable devices and then move to the section that shows what bootable devices there are and screw around a little and switch what order things boot and after a few it should work i dont know what type of laptop it is exactly you have so i dont know what exactly the devices you have on it
Bootable devices are pieces of hardware that the BIOS can load an operating system or special program off of. These can be floppy drives, CD drives, hard drives, USB flash drives, tape drives, SD cards, and certain ROM chips.

Secondary storage device is USB and also the external hard disk are external devices these are best for external memory.
list of external devices: 1.Mouse 2.Keyboard 3.Speakers 4.hardrive (external) 5.Microphone Do you think these aren't essential? External devices such as external hardrives, come in place when internal hardrives cannot be installed. Duh
A bootable device is, as the name suggests, any storage device that the computer can "boot" from. In this case the word "boot" refers to the loading of the operating system. So any device you can load an operating system from is a bootable device.In modern computers, the hard disk is generally the primary boot device. However most new computers can also boot from a CD-ROM or DVD drive (usually for the purpose of reinstalling an OS to the hard disk) so it is also a bootable device. Many systems also have the ability to boot from USB thumb drives or external hard disks and back in caveman days, floppy disk drives were also popular boot devices.
External devices can carry out all sorts of different functions.
the need for devices to function without an external power source
External devices are used for storage just like internal devices but with the added bonus of being portable and not requiring space inside your computer. This usually comes at the sacrifice of access time or write times. Depends on the interface used for the external device.
External. Internal devices would be something like a CD Drive, while an external device is a keyboard or mouse for example.
