The computer wishes to boot a program from a portible device, E.G. Flash drive, CD/DVD etc.
'Cause my brother fell my laptop on the ground and I don't know if it's already broken. I'm so scared 'cause this laptop is so expensive. :(
This depends on your expertise and preference. Typically I suggest setting your optical media drive (CD/DVD/ETC) as your first boot device, but this tends to slow down your boot time ever so slightly as the drive seeks in order to figure out if the disk in the drive is bootable media or if there's even a disk in the drive. It makes installing boot-level media far easier, however. If you know what you're doing and know how to manually open the boot menu without going into setup, then set your hard disk as your first boot device, followed by your optical media drive, then finally any other medium such as floppy drive, removable media, etc.
Faulty hard disk Nonbootable media in a drive
I hope you have taken back of OS in storage device,use that media for resroring OS. Insert a media boot with xp bootable CD , at start up you will see for auto mated system recovery press F6 or F2 go for it choose media to restore, it's done.
First thing is, the CD has to be a 'Bootable CD'.Change the 'First/Primary boot device' in the bios setting to 'CD ROM'. Ususally it will be floppy disk, by default. Insert the bootable CD into the CD drive. That's it!!

When a computer boots up and the optical drive does not contain bootable media, the system will move on to the next boot device in the BIOS boot order. This could be another optical drive, a hard drive, a USB drive, or a network boot, depending on the configuration. If none of the boot devices contain bootable media, the computer will typically display an error message such as "No bootable device found" or "Operating system not found."
To boot from a DVD in Ubuntu, first, insert the DVD into your optical drive. Restart your computer and access the BIOS/UEFI settings (usually by pressing a key like F2, F12, ESC, or DEL during startup). In the boot menu, set the DVD drive as the primary boot device. Save the changes and exit, and your computer should boot from the DVD.
Your computer will not boot, it will probably freeze.
You may have lost the boot record on the hard drive or the hard drive may have failed. Try booting from a floppy or CD, whatever rescue boot device you have. If you can look at the C: drive from the alternate boot device you may have just lost the boot record. If you can't get to the C: drive you may have either a drive or a controller failure.
