 Warning: For Windows, there is no support for booting from a BIOS/GPT partitioning scheme. If you have already installed Windows with a BIOS/MBR partitioning scheme do not convert the drive to GPT! Windows will fail to boot if this is done - irrespective of the bootloader used to chainload Windows. One can either install Windows in UEFI mode and use an UEFI bootloader (which uses GPT), or possibly restore/install Windows on a BIOS/GPT hybrid MBR. Warning: For Windows, there is no support for booting from a BIOS/GPT partitioning scheme.

 +===BIOS / UEFI===
 +BIOS(basic input/output system) is the program a personal computer's microprocessor uses to get the computer system started after you turn it on. It also manages data flow between the computer's operating system and attached devices such as the hard disk, video adapter, keyboard, mouse and printer.
