China DOS Union

I've been busy installing machines these past two days, and having to boot from a boot disk every time is too much trouble.
Can I put the boot disk onto drive C:? It just needs to have the boot disk function; I don't need anything else.
I heard from a net friend that format c: /s can do it, but I tried several times and it still didn't work. Afterward there was only the command.com file on drive C: (there may have been other hidden ones too; when I ran antivirus it seemed to show 4 files). Booting from drive C: still wouldn't work, and then I copied the data from drive A: to drive C:, but that still didn't work. I'd like to ask if there's any way to do this? Thanks!

Which DOS are you using, and what exactly is the hard disk situation?

I'm booting with a 98SE boot disk. The hard disk is a bit old, it's a 4G Seagate; I don't know the exact performance specs. The memory is also very small, it seems to show only 28M, hehe!
So under normal circumstances, if you boot from a boot disk, can format c: /s make drive C: bootable?

Don't use a WIN boot disk. Please download a DOS boot disk here and try it, for example an MS-DOS 7.10 boot disk.

OK, I'm trying it now, thanks!
I'd also like to ask: if I directly extract the image onto drive C: of another hard disk, can I boot directly from drive C:?
