If you install multiboot, it is a good idea to install Windows before installing the Linux system because :
- Linux in the installation, you can choose to install the bootloader in the MBR or individual partitions of the boot sector, and the Linux loader can be manually set menu (m1,m2 in the previous article diagram), so you can be in the Linux boot Loader the option to add Windows to the boot.
- When Windows installs, its installer will actively overwrite the MBR and the boot sector of its own partition, you have no choice, and it does not allow us to choose the menu function.
Therefore, if you install Linux and then install Windows, then the MBR boot loader will only have Windows options, and there is no Linux option, because the original MBR Linux boot loader will be overwritten. If this is really the case, is it necessary to reinstall Linux once? Of course not, you just have to use a variety of methods to deal with the contents of the MBR. For example, the use of Spfdisk (http://spfdisk.sourceforge.net/) software in Chinese to install the Identification Windows/linux management program, but also can use the Linux rescue mode to save the MBR.
