i just made MS-DOS 6.22 Floppy IMG File , it loads RAMDRIVE.SYS , EMM386 and HIMEM.sys drivers on boot , then copies Windows 2.03 files to ramdrive and runs Windows. but when i try booting into it, it stucks at "Starting MS-DOS" . then Dosbox-X reboots

I guess EMM386 may cause issues sometimes. Can you try disable the EMM386 driver and see if it helps?

Can you try a different version of EMM386.EXE and/or HIMEM.SYS?

My understanding is that some older versions use an undocumented instruction on 286 and 386 processors known as LOADALL if it thinks doing so will allow access to extended memory without the time consuming task of switching to and from protected mode.
