China DOS Union

Expert, please help~~~
If you don't handle it, then only DOS will boot. If you rashly use sys to transfer the system files, Win2000 won't boot either.

I just didn't handle it~~ now I can't get into WinXP~~
How do I fix it?

Could you explain it in a bit more detail?

To put it simply, actually the best method is to first boot the system with the MS-DOS 7.10 boot disk I made. After booting, run the following commands under DOS:

SYS A: C:
SRCBOOT C: C:\BOOTSECT.DOS /S
BOOTPART WINXP BOOT:C:
Then add the line for booting DOS into BOOT.INI;
If necessary, also copy A:\MSDOS.SYS and A:\LOGO.SYS to C:\
.......................
I did it this way.... and then I couldn't get into WinXP~~~~ I could only get into DOS

I used the boot disk made by wengier, and after booting
I used these commands~
SYS A: C:
SRCBOOT C: C:\BOOTSECT.DOS /S
BOOTPART WINXP BOOT:C:
Then after rebooting it went straight into DOS~

Don't post carelessly.
