You can use some MS-DOS diskette.
WinXP let you format a minimal MS-DOS diskette:
Use the appropriate option in "format diskette" dialog.
You will then have a diskette that can boot wour PC with the MS-DOS
portion of Windows ME (sorry, I don't recall this MS-DOS version, surely
7.2 or 8.0).
There are ONLY the core system files on this diskette( no foreign
keyboard support for instance, no fdisk or anything like this).
Some old Windows 98 Emergency Repair Disk can also boot your PC with
much more support (fdisk, format, CD support...)
Some third party products can also make it possible for you to build
some boot-diskettes with a lot of extra features, such as Windows
Network support : you can access your Windows network shares from a
computer that is booted with such a diskette, and use any dos based
tool (ghost, partition magic) in conjunction with the access to
network shares
