... after two burning attempts in total, neither succeeded. The first time, they directly burned MSDOS.ISO into the disc. After it was burned, I put it into the CD-ROM drive and set BIOS to FIRST　boot (CD-ROM), but it didn't work, and the operating system again selected windows2000.
The second time, they extracted msdos710cd.iso and burned the extracted contents onto the CD. After burning, I inserted the disc into the drive again, and it still didn't work. It still went into windows2000 again ...

These two burning methods are obviously both wrong. An ISO file is a CD image file, and it should be directly written to the disc as a CD image, rather than being burned onto the disc as an ordinary file or extracted and then having its contents burned onto the disc. Taking Nero as an example, after starting it please choose "Open...", then select the ISO file you want to burn, and you can begin burning.

Re OP:
Wengier's reply only solves the CD burning problem, while obviously what the OP wants is how to get into pure DOS under XP and run Ghost.

As for burning iso image files, this post answers it more precisely:

As for how to get into pure DOS under XP, there is a post in this board's pinned digest index that systematically solves this problem. Link: http://www.cn-dos.net/forum/viewthread.php?tid=10788

Let me provide another piece of software:

This is a self-extracting installation file that supports grub+memdisk and VFloppy booting.

Thanks, you two brothers. I'll continue and try again following your methods. I believe this time it should work. Hehe, looks like that disc wasn't burned properly. It should be that those people in the shops out on the street don't know how to burn ISO images. Hehe, this time, with your guidance, boss, I can give them a lesson. Ha.....
