China DOS Union

GNU GRUB is a very powerful and practical multi-boot manager. Through it, you can easily achieve the boot of various operating systems or boot from IMG image files. Now there is the DOS version of GRUB (namely GRUB for DOS), which can be directly loaded in the DOS command line or CONFIG.SYS to boot other operating systems, and can also install GRUB to the MBR of the hard disk through GRUB for DOS, so that the GRUB multi-system boot interface will appear as soon as you start the computer. The method to install GRUB to the hard disk MBR is:
1: First copy the two files stage1 and stage2 to the C:\GRUB or C:\BOOT\GRUB folder;
2: Run GRUB for DOS, then enter the commands:
root (hd0,0)
setup (hd0)
That's it!

If it is a floppy disk, you can also use this method. The method is to replace hd0 with fd0 and copy the stage? file to the corresponding folder of drive A.

It is recommended that everyone test and use it!

Okay! Give a download link, there are many posts and I can't find it for a while.

I think when using in the hard disk, it's not as good as using spfidks, just placing it in the MBR, so that you don't have to worry that after the C drive is formatted, there is nothing left.

GRUB is also placed in the MBR. It supports IMG, direct multi - system, while SPFDISK does not support it (it can only support independent partitions).
