>Popular MBR code programs were created for booting PC DOS and MS-DOS,

>the fdisk partition table scheme to be in use, and scans the list of
>partitions in the MBR's embedded partition table to find the only one

>volume boot record (VBR) of the active partition.

>此外在维基百科VBR的页面(http://en.wikipedia.org/wiki/Volume_boot_record)上有说明:
>The code in volume boot records is invoked either directly by the

>择译如下:

>If you intend to dual-boot Windows, then you should avoid installing
>GRUB to the MBR. The reason for this is that Windows occasionally
>overwrites the MBR, for instance, when you reinstall it, and that
>could be quite often. When that happens, your Linux system will seem
>to disappear as your system starts booting directly into Windows,
>bypassing the boot menu altogether. To avoid this, install GRUB to the
>boot sector of the active partition instead.
>
>想双引导win的话, 为了避免重装win把mbr覆盖导致linux"不见"了, 建议避免装mbr上, 应该装在活动分区.

>There’s an exception to that rule: If you are installing Linux to a
>secondary hard drive, and no part of it will be on your main hard
>drive, then you must install GRUB to the MBR, and take your chances
>with Windows overwriting the MBR with its own at some future date. If
>this happens, you’ll have to use a Linux rescue CD to get GRUB
>reinstalled. (I’ll cover this procedure in the future.)
>
>以上规则有一个例外: 如果把linux装在从盘, grub必须安装在mbr, 然后乃自行搞定win的问题吧.

>If, however, Linux will be the only operating system on your computer,
>it’s perfectly safe to — and you must — install GRUB to the MBR.

>然而, 如果linux单系统环境的话, 装到mbr里吧!
