Problem with booting any non-linux iso from grub2 menu

Problem with booting any non-linux iso from grub2 menu

Dear Grub2's developer team,

I've spent several days trying to do something I get using grub4dos:

- booting a Windows 7 Installer ISO (with bootmgr) from the menu and...
- booting a Hiren's Boot Cd ISO also from the menu

Other ISO's (any linux-based iso) work fine.

Could you, please, tell me exactly what I have to write in the .cfg file to
boot a Windows 7 (and XP, if it is not much..) ISO ? And what about Hiren's
Boot CD??

I have to say that I've looked for those topics on Google, and there isn't
anybody who solves the problem...or that is my conclusion after hours and
hours looking by Google...And in the official manuals (and non-official
others) I've found for Grub or Grub2, also say nothing to respect.

Please, help me!

Best regards.

Windows doesn't support loading from such config. While it's possible to 
simulate disk through BIOS it won't get you far as windows will lose the 
disk the moment it uses native drivers

AFAIR Hiren is DOS-based. You can try load it using memdisk from 
syslinux package as intermediary (remeber to use linux16 and initrd16). 
But even under DOS some tools may choose to use direct access and so 
will fail.
I feel like it's more appropriate to use GNU/Linux CDs in most cases 
which is aware of it being loaded the peculiar way rather than using tricks.

I've documented the issue in manual now.
