Don't click. I still need to ask you to help analyze.

I followed your method and used the MAP command to swap the hard drives. The commands are as follows

map (hdo0) (hd1)

map (hd1) (hd0)

rootnoverify (hd1,0)

chainloader (hd1,0)+1

boot

Then there is only a cursor flashing there and it doesn't execute.

What's the reason? Don't click. Help take a look in FastSLZ, thank you

Your first command was a typo? Try this:

map (hd1) (hd0)
map (hd0) (hd1)
map --hook
find --set-root /ntldr
chainloader /ntldr
boot

Haha, thank you Budian. It has been successful. :D

According to the above command, it's okay. It's the problem of my own hard drive. The MBR was lost, and it was fine after rewriting one. Thank you for your attention. I didn't expect to get a reply so soon.

There is also a problem, how to modify the built-in menu to prevent it from searching for the local MENU.LST. When starting up now, it always first shows the built-in find MENU.LST, and then shows my MENU.LST. It would be great if the built-in one can be used. I analyzed the dwarf's DOS toolbox, his is using the built-in menu, but there are two files, one is ARLDR and the other is argzs, and there is no MENU.LST in the boot directory.

I don't agree with modifying grub myself. What does it mean? That is, if you want to modify, submit the modified patch to the project maintainer. If the project maintainer thinks your modification is reasonable, he will accept your patch. Otherwise, I personally think that's making trouble.

As for GRLDR, what it executes preferentially is not the built-in menu, but menu.lst in the root directory. Only when there is no menu.lst in the root directory will it execute the built-in preset_menu menu.

So, unless you explicitly delete menu.lst in the root directory to ensure it doesn't exist, then your built-in preset_menu cannot guarantee that it will take over control. Although you can delete the menu.lst in the root directory yourself, other software may create this file. Therefore, the execution of your built-in menu is always not absolutely guaranteed.

I directly put the installation package on the USB flash drive. How should I boot? I have tried all the above methods, and it just restarts after the screen flashes. If I switch to ntldr, it shows a boot.ini reading error and then stops.

Boss, just use
title Install Windows XP (by Makubes)
chainloader /SETUPLDR.BIN
No need to write hd or something, this is simple and convenient, remember to be in the same directory~
