Hi

Im trying to get rid of that multi-second delay there is, while pxe booting into WinPE. (Without WDS)

I have read here: http://www.syslinux....rch/014174.html that you will use dhcp option 252 to point to a wpad.dat file on a webserver, which contains the path to the BCD file, so the bootmgr.exe knows where to find it.

Has anyone here experienced with this? Heck, I dont even know if I have done it right? My dhcp is currently

next-server 192.168.1.3

bootfile boot\pxeboot.n12

option 252 ascii "192.168.1.3:85/wpdat.dat"

The above configuration is from my cisco router, which does give me the opportunity to experience with this

"boot\BCD, bootmgr.exe"

Im not sure what Im doing wrong? Any help will be very appreciated guys!

Well, surely you miss a leading backslash and you have "wrong" quotes (when compared to the given source):
http://www.syslinux....rch/014174.html

Option 1) If DHCP option 252 (wpad) has been provided in the format "\path\to\BCD\file", "bootmgr.exe" will simply load that file from the TFTP server and use that as the BCD-file.

You can try with:



"\boot\BCD", "bootmgr.exe"

but cannot say if the issue is that one.

As a side note, if you use a DHCP server that has been developed to provide among others that option through BINL, you should have not the issue, and if at the end of the day what you are looking for is a faster PXE booting, you may want to experiemnt with alternative approaches, http/sanboot or wimboot:
