No bootmgr.exe

[ylafont]

I am trying to boot a .wim file with wimboot and get the following:

Emulating drive 0x81
FATAL: no bootmgr.exe
Press a key to reboot

LABEL Microsoft Windows 8.1
MENU LABEL ^D) Windows 8.1
com32 linux.c32
APPEND wimboot initrdfile=winpe/bootmgr.exe, winpe/bcd, winpe/boot.sdi, winpe/boot.wim
TEXT HELP
Windows 8.1 Installation CD
ENDTEXT

Is there a fix to this?

This is a PXELINUX configuration. Are you sure that you have shao's custom patch that makes it possible to chunk all of the files together in the same way as iPXE does it? If not, it won't work. You can create an initrd manually with all of the files to continue using pxelinux, but my suggestion would be to use iPXE to do it directly as suggested at http://ipxe.org/howto/winpe.
