Dual boot - DOS 6.22 and Windows 7 Pro

Hi,

Here is what I did:
1) Install "DOS 6.22" on a fresh 500GB Harddisk.
2) The "DOS 6.22" can bootup successfully. It is on a FAT 2GB partition.
3) Then install "Windows 7" on a 100GB NTFS partition.
4) The "Windows 7" can bootup successfully. However, I can't bootup the "DOS 6.22" anymore. In Windows 7, the DOS partition is not assigned any drive letter and therefore I set it as "F:"
5) Install the "EasyBCD 2.1" on "Windows 7" and add an entry for "DOS 6.22".
6) I notice that a folder "NST" is created on the "F:" (the DOS FAT16). There is an "AutoNeoGrub0.mbr". Also there is a "ANG0" file on the root directory on "F:"
7) Everytime I want to boot from the "DOS 6.22", it just brings me to a "GRUB" prompt.

The "real-mode boot sector" is strange that the "path" points to "\NST\AutoNeoGrub0.mbr". I think this is the reason why the "GRUB" prompt always comes up.

Does anyone see this problem before? How do you solve this eventually?
Thank you

How did GRUB get involved? It would have been easiest to just use 7's bootloader and add DOS to that.

EasyBCD uses GRUB internally to load DOS.

I don't know! The "real mode boot sector" just pointed to the GRUB loader after I added a new entry for DOS. And it cannot be modified.....

There seems to be something wrong here - are you guys using EasyBCD 2.1?

It looks like I'm going to have to re-test this. It was working perfectly the last time I tried it...

I was replying to CG's question in the previous post about the version of Easy in use.
The answer was in point 5 of the OP (Original Post)
