You will need to install the Windows 10 Insider Preview build on a device that has been previously activated with Windows 7/ 8.1 or with a Windows 10 product key. For more details please see the article: Activation in Windows 10. If you don't have a valid Windows 7 or Windows 8.1 or Windows 10 installed, an alternative is to download the Windows 10 Enterprise 90 day trial,  (Use Disk Management to shrink your existing Windows 7 / 8.1 or 10 partition), and install Enterprise on the new partition or unallocated space, activate it, then join the Windows 10 Insider Program.

7) After downloading the correct .iso file install HashCalc and validate the SHA1 hash value listed above is correct.


(Note: If the download is not corrupt, the value HashCalc returns will match the SHA1 value.)

a) Launch HashCalc and navigate to the location of the .iso file you downloaded.

(The default download location is: C:\Users\User account name\Downloads)

b) Remove all check marks from the list of HashCalc options except for SHA1.

c) Click the ‘Calculate’ button and wait for the SHA1 string of letters and number to be displayed.

Note: The hash value is not case sensitive as upper and lower case letters are considered the same.

8) Next use ImgBurn (or Gear ISO) to create a bootable DVD.


Note: When installing ImgBurn, choose the “Custom Installation (advanced)” option and remove the check mark(s) to eliminate unwanted options, including Optimizer Pro (I do not accept) which is not needed.

(The steps are the same for Windows 7, Windows 8 or 10), except you are not creating a Repair disc but a full installation DVD)

Note: Always use high quality DVD+R media and the slowest burn speed (4x or 6x) if offered a choice.

Note: Skip to step #4 to create a bootable Flash / Thumb drive.
