Although not essential, it's a good idea to verify the integrity of a downloaded ISO file. To do that, you'll need to check the ISO file up against its MD5 file, the latter which contains a data string that matches the ISO. If the string matches, the download went perfectly; if not, you'll need to download the ISO again or have a pre-made disc sent to you so you can avoid downloading the ISO.

Follow the directions for your platform:

Contents

Windows (All Versions)

  1. Download the correct MD5 file for your ISO file. You'll know the correct MD5 file because it's file name will match the name of your ISO file, except for the file extension, .iso and .md5, respectively
  2. Open the MD5 file in Notepad and copy the long string of numbers you'll see to your clipboard
  3. Download WinMD5Free
  4. Double-click on the icon for it. It will run without the need to first be installed and look like the below
  5. Click "Browse" and navigate to the ISO file
  6. Paste in the long string of numbers from the MD5 file in to the "Verify" section
  7. If the numbers match, your ISO file is good to go; if not, download again

Mac OS X

  1. Download the correct MD5 file for your ISO file. You'll know the correct MD5 file because it's file name will match the name of your ISO file, except for the file extension, .iso and .md5, respectively
  2. Download MD5 and run it.
  3. Click "Choose file" and navigate to the ISO and let it calculate the MD5 sum
  4. Open the MD5 file in Text Editor and compare the number strings
  5. If the numbers match, your ISO file is good to go; if not, download again
