If you have to install 64bit Windows Vista, 7 or Server 2008 than you may come across an error that goes “Select CD-ROM Boot Type“. This will happen when you try to boot from the hard drive after the Windows DVD has copied over some of the files during the first phase of installation. We searched the internet and came across hundreds of people begging for assistance over this error and we have the solution here and tested it recently with Windows 7 64bit Enterprise.


  1. Take your CD/DVD/ISO and copy all the contents to your computer.
  2. Download OSCDIMG.exe from here: CLICK HERE FOR DOWNLOAD
  3. Now load up the command line and run the following command “oscdimg -n -m -bc:\windows7contents\boot\etfsboot.com c:\windows7contents c:\newwindows7dvd\newwindows7dvd.iso

The program will produce for you a brand new ISO to use that will not give you the “Select CD-ROM Boot Type” error in the future.
