Hello everyone, i seem to be havin a little trouble creating an ISO with student D/L Windows 7 pro 64 bit i followed the instructions from the link
Make bootable iso from student d/l
downloaded the OCSDIMG file and put it into my windows system32 folder
ran the cd /d C:\windows\system32, succesfully.

ran the oscdimg -u2 -b"C:\Documents and Settings\David\Desktop\expandedSetup\boot\etfsboot.com" -h "C:\Documents and Settings\David\Desktop\expandedSetup" C:\7.iso and when i hit enter i get
ERROR could not delete file "ubC:\expandableSetup\boot\etfsboot.com"

and takes me back to a C\windows\system32 prompt.
