You can make your own ISO. The necessaries are all there.
I use this procedure. There have been follow up posts that it did not work for some, which I could not fathom. I have used this for a long time and it has never failed. (Best to prepare a dedicated folder for this.)
The needed file is too big to upload here, so download and unzip it from here:
https://onedrive.live.com/?cid=905852d5563ad391&id=905852D5563AD391!13344&ithint=folder,zip&authkey=!AFwVy9giSjmJobs
to the prepared folder.
Open an elevated command prompt and navigate to the prepared folder.
ESDtoISO C:\RecoveryImage\install.esd (First check that the file is, indeed, in that folder!)
Eventually you will see the command:
Select (i)so or (Q)uit. Obviously you select "
i"
In some cases, the command panel may report errors. You can ignore these, should it happen.
The process takes a while, according to your equipment. With my average gear, it takes about ten minutes. At that stage IT IS NOT complete. Wait and it will say exporting image, with a percentage countdown.
