How do we do that?
If you are using Windows
Choose preferably a program made to handle the downloads, such as Free Download Manager, which is a program under a GPL license, or a torrent client, such as Transmission.
When the download of an ISO image of your future distribution will be done : NEVER extract it! It would become useless…
Once your download done, verify the integrity of the dowload using a program which checks the MD5 digital fingerprint of the ISO file, and compares it with the file having a .md5sum extension name coming along with the ISO.
For the first one, a version in French is available, “la version en français”.
We can also use Install-winMd5Sum.exe
You can also burn the ISO image with a program such as InfraRecorder, another Free open source software for Windows. Use a low speed to burn, (for example 5x) on a CDROM, the result is often more reliable that way.
If you already use GNU/Linux
Open a console, type the command md5sum, followed by the -c option, and the name of the md5 file which should be located in the same directory as the ISO image which goes along with it. For instance:
md5sum -c name-of-your-file.md5sum
once the command line entered, the console should return the following message back:
By having the ISO image and the md5sum file coming with it in the same directory, some burning software check the md5 for you before proceeding.
