wimboot and Emulating drive 0x80

[NiKiZe]

What is the actual issue you are seeing, is it a hang?, if so when? do you get any error messages etc?

You could try building ipxe with debug enabled to get more info about where in the boot process any issue pops up.

small note about bootmgr.exe it should automatically be extracted from the .wim file - so should not be needed as initrd (and on rare occasions I have seen it being an issue due to wrong bootmgr being provided)
