Using Osdimg to create an ISO Windows PE

Hi Everyone,
I'm being puzzled with the error when I try to build an ISO of Windows PE.
The command I use is:
Oscdimg -n –bc:\winpe_x86\etfsboot.com c:\winpe_x86\ISO c:\winpe_x86\winpe_x86.iso
(And Typed it in not copy and paste since there is a bug about that)
I get an the following:
ERROR: Could not open boot sector file "c:\winpe_x86\etfsboot.com
Error 3: The system could not find the path specified.
I can ask for help to anyone? Please?
Regards.
Lewis

It cannot find the file etfsboot.com
Make sure it is in the location you specified... in your case:
c:\winpe_x86\etfsboot.com

Hi everyone,
I found the problem.
It seems that the file that was in the root directory is not a valid copy, I copied the one that was installed on c:\winpe_x86\boot to the root.
Thanks,

c:\winpe_x86\etfsboot.com
I'm encountering the same problem as above... But even when I'm searching for the bootfile on the entire C:\ I'm unable to find the file... Where should I look for this file? And am I supposed to just copy the file?
Edit:
I was using the ia64 instruction for a server installation. When I'm using the x86 instruction it prompts automatically... So I'll use another server to test install this. Thanks anyways!- Edited by HenkDeGoudvis Thursday, February 04, 2010 11:26 AM update info

note that there is no space between the -b and the bootfile path!!!- Proposed As Answer by Christian Lagerhorn Monday, March 01, 2010 12:55 PM

Not sure if you guys found the solution, but had the same problem.
I copied the command from the instructions and pasted it into the command window. I resolved it by typing the command directly, it seems that the copying messed up the double quotes.

I had a space between the -b and the path.
Once I tightened it up, I was fine. I put the two WAIK files I needed in WAIK-bits: oscdimg.exe and etfsboot.com
So, to create a bootable ISO, this worked for me.
.\WAIK-bits\oscdimg.exe -m -n -b.\WAIK-bits\etfsboot.com .\DVD-FILES .\DVDout.iso

Dear Lewis,
i also faced the same problem.
First verify the paths and filenames are correct and type the full command manually.
Thanks
Vijay,

Hi
I used the file named efisys.bin because the etfsboot.com files was missing too. This is on an ia64 processor and it worked I tried different ways that did not work but it seems this will work.
oscdimg.exe -n -bc:\winpe\efisys.bin C:\winpe\ISO C:\winpe\winpe.iso

Only use ia64 if you are using an Itanium processor. Otherwise use amd64.

Thanks SW...I think you deserve some points for this. I'm using the x64 environment and ran into the missing etfsboot.com error. Turns out I had used ia64 instead of amd64 and that was the problem. I also just noticed that you posted this on my birthday! Thanks for the gift.
