This is actually reverse of almost all guides out there.
What I'm trying to do is boot a build of iPXE using Windows BOOTMGR. I've already got it working successfully with Grub4Dos and Grub (as well as through normal PXE as well), but I can't figure out how to make it work with Bootmgr.
My reason for doing is is that I don't really want to install grub on every computer I want to be able to boot iPXE from.
The reason I can't just use PXE is that I plan on having the relevant computers abroad, and iPXE is used to download the boot images over the internet.
From what I've read, I can use a file stored on the disk as "Bootsector", such as Windows XP's NTLDR, but I can't seem to generate a file that is acceptable for this purpose, even though the USB and HD images buildable are about the same size...
Any ideas/help would be awesome.
