Windows 7: DVD ISO build Method by Microsoft

Hi Chris,

Nice tutorial.

MS use an app. called cdimage.exe.



In the tutorial , you are using oscdimg.exe - in terms of what you are doing here, it does the same job.

oscdimg.zip

It is probably easiest to put oscdimg in system 32 - so when you open a cmd prompt, you are right there.



oscdimg.exe -u2 -m -b[path to bootable image file] -h[path to windows files] [path and filename to create]

-u2 Creates UDF file system 1.02

-m Allows creation of image file larger than 700mb CD limit

-b Indicates the location of the boot image

-h Includes hidden files

-l Sets volume label of DVD, if you like. -l[Disc name or label]

-t Sets the date and time , if you like. -t[MM/DD/YYYY:HH:MM]



Note: Space before each command switch. No space between switch and path. Do not include the brackets in the path. If the path includes spaces, enclose it in "".

With cdimage.exe ver.2.52(108 KB):

-Place your folder Windows 7 in your C:\ drive.
-Place your cdimage.exe in your C:\ drive.
-Run Command Prompt "as Administrator".
-When Command Prompt appear, type "cd\” without the quotes to change to C drive.
Type (copy/paste this) the command cdimage -m -u2 -bC:\Windows 7\boot\etfsboot.com C:\Windows 7 C:\Windows 7.iso and you will see that it’s creating Windows 7 ISO image.

Hello,

Couldn't you just use a program like ImgBurn to do the same thing much easier, or am I missing something again?

Hi Shawn,

The ETFSBOOT.COM program creates the CD boot sector.

Some 3rd party burning apps. do not seem keen to accept it as a valid boot image.

I haven't tried ImgBurn to do it - you may need a number of manual settings to get it work.

Give it a go if you have the time and see if you can get it to work.

To avoid using command line tools - the easiest is Vlite.

Just run as admin on the vlite.exe. Click Install Wimfltr>next.

Tick Bootable.iso>next. Browse to Windows Files>next. Select Create Image>next. Select a place to put the .iso>next. That's it.

To avoid any extra downloads , it's worth getting hold of vlite v1.1.6

Hi brink. I attempted this method before and I does not work because it does not have the boot sector info.

Ah, I see now. I haven't messed with it any in Windows 7, but ImgBurn does have an option to do something similiar to this that may work as well.

Haven't tried it - but you might get ImgBurn to work if you extract the boot image from a dvd and save it somewhere ( Build mode - at the bottom right).

Then go to Advanced >ISO9660 and check the box about Don't add the ;1 Version number. ( Inexplicably, EFTFSBOOT.COM doesn't set the filename up in the expected ISO standard - that may overcome the problem).

I got it to work .

a) Either use ImgBurn to extract the bootimage from a bootable dvd. Imgburn labels it .ima.

b) Or extract the boot image from an iso on the HD using PowerIso/Ultraiso, it will saved with .bif.

c) Or browse to etfsboot.com in the windows files - it is in the Boot folder.




Under Mode tab, Select Build mode:



Select File >browse to the windows installation files folder ( I was using vista pe I wanted to make bootable)



Follow these settings under Advanced> ISO9660 Tab:



Follow these settings under the Options Tab:



Follow these settings under Advanced> Bootable Disc Tab :

Browse to boot image - either the one you extracted from dvd or .iso



OR select etfsboot.com in the windows files Boot folder:



Select Destination:



Click the Build button:



There you have a bootable .iso :

Very nice SIW2.
