It usually happens when the boot record is corrupt, or the storage is corrupt. To fix the boot error, you must use the advanced recovery drive and run the bootrec /FixMbr, bootrec /FixBoot, bootrec /ScanOs, and bootrec /RebuildBcd commands.

The location can be anywhere, including fixed storage devices, USBs, and DVDs. Technically speaking, BIOS or UEFI only looks for loading information and will boot wherever the OS or Recovery solution is available.
