Bootable ISO - Create from an Older ISO

How to Create a Bootable ISO from an Older ISO​

   Information

This small how-to covers just the fundamentals....

• Extract a Boot Sector file
• Create a new ISO with the extracted Boot Sector file

Here's how:

   Note

I use UltraISO for this method, but the basics should be the same for most ISO editing software

Firstly, open/run UltraISO (or similar)
1. Insert a Bootable DVD (e.g. Windows 7) Click Bootable then Extract Boot File from CD/DVD...

2. Select the drive and destination for the BIF file then click Make

3. You will be presented with the following message. Click Ok then 'Close'.

4. Browse for the files you wish to have created into a Bootable ISO.

5. Click Bootable and Load Boot File..., and browse for the file you just created.


You can type *.* into the filename bar to view the new file



6. Click the Burn Icon to burn the new Image to disk, or Save As to save the newly Bootable ISO.

Hope this answers a lot of people's questions

Nice tutorial Shark.

I assume that is for when you have the windows files and you want to make a bootable .iso.

Ultraiso is saving the bootimage file etfsboot.com , with a .bif extension.

If you don't have a paid version of PowerIso, Ultraiso, etc - pretty much any burning suite you have will make a bootable iso for you.

It will ask for the windows files - you know where they are - so browse to those, and it will also ask for the bootimage file .

It is called etfsboot.com and is inside the windows files in the boot folder here :



Very few app. can utilise etfsboot.com - so extract the boot image as per the tutorial, using the free versions of PowerIso, UltraIso, or MagicIso - and use that .bif or .img you extracted when asked.


Just browse to it when asked by your burning app.

Ah, cool, nice addition

Isobuster extracts a .img file - your burning app.will probably happily pick that up.



EDIT : Vlite is probably easiest method. Browse to the windows files, click Bootable .iso , create image

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.

Hi, welcome to the forums.

Yes you can, there's no tie to version numbers. The RTM if downloaded from MSDN or Technet will be bootable anyway
