img to iso

English Applications
#1

I have an img file (openelec) which I would like to use on a flash stick. suse imagewriter will only see an iso file.
Can someone recommend a method of either installing the img file to make a bootable usb stick
or to convert the img file to an iso.

#2

This is a stab in the dark
But just try this:
Make a copy and rename it to have the .iso extension

But likely you read the direction @openelec ?
There seems to be some specific directions there but not related to a .iso

#3

Thanks - I renamed to an iso and used suse imagewriter - it works perfectly.
The instructions on openelec are more windows centric or too complicated.
So this method should work for all img files - I noticed that lots of videos are stored as .img

In principle no, img are hard disk images and they usually use the old fat file system, iso’s are CD images where files are orginized according to the ISO 9660 file system, suse image writer probably supports img files it could be that the img extension wasn’t added to the list.
There are a lot of applications that can open img files (atm no linux apps come to mind) 7zip for windows can list and extract files from hard disk images (iso’s too)

#5

AFAIU, imagewriter doesn’t really care about the underlying file-structure (payload). It is used for low-level copying ‘bit-by-bit’ to a given medium, similar to the ‘dd’ utility. As long as the ‘image’ file contains a valid file-structure for the media concerned, then the device written to will contain a bootable system. (So, while IMG and ISO archival formats themselves are different, what really counts is that appropriate data is written to the desired target media.)

Explained well here:

Thanks for the explanations and links. They do explain a lot.
So it looks like dd will do a bit by bit copy including an mbr. Suse imagewriter will create the mbr and go to the correct spot to start the program

As far as I know, imagewriter does the same as dd, but graphically.
