Hi @ all,
here is the official build way (by Microsoft) to create a bootable Windows 7 DVD.
I´m using build 7600.16385 64 Bit for this How To.
Extract the files to C:\7600.16385
Download and install WAIK from Microsoft:
Download details: Windows® AIK for Windows ® 7 RC
Open a cmd (Start > Run > cmd) and go into this folder:
cd C:\Program Files\Windows AIK\Tools\amd64
run this command, now:
oscdimg -u2 -m -h -b"C:\7600.16385\boot\etfsboot.com" "C:\7600.16385" "C:\7600.16385\7600.16385.090713-1255_x64fre_client_en-us_Retail_Ultimate-GRMCULXFRER_EN_DVD.iso" -lGRMCULXFRER_EN_DVD
This will create a bootable "untouched" dvd iso like from microsoft. (see screenshot)
