Problems when GRUB4DOS boots the system from the first partition of the first hard disk? - China DOS Union Forum

I made a bootable USB drive and used GRUB4DOS to boot some IMG tools from the USB drive, but why doesn't it work when I add the option to boot the system from the first partition of the first hard disk?

The MENU.LST file code is as follows:
# This is a sample menu.lst file. You should make some changes to it.
# The old install method of booting via the stage-files has been removed.
# Please install GRLDR boot strap code to MBR with the bootlace.com
# utility under DOS/Win9x or Linux.

# color blue/green yellow/red white/magenta white/magenta
timeout 30

20000,xp,2003 find --set-root /ntldr chainloader /ntldr vista,2008,win7 find --set-root /bootmgr chainloader /bootmgr This should be relatively normal. I have already used grub4dos. Is makeactive necessary?

This method isn't working, heh. I don't know if makeactive is necessary. I modified it according to the original MENU.LST file, heh

Why doesn't it work? Is there any error message prompted?

This situation is mostly because the mainboard regards the booting USB flash drive as a USB external hard drive, so hd0 is the USB flash drive itself, and the original first hard drive becomes hd1...
