Taking my first Linux course and, ironically, I think I've hit a problem that could be fixed by someone proficient in Linux!As part of the course I'm taking, we're required to download and install CentOS 7. I'm having problems with the installation part.Some context:Downloaded the 'DVD ISO' file from official websiteFile name: CentOS-7-x86_64-DVD.isoFile size: 4.33 GBRunning OS X El Capitan v10.11However, when I double-click on the file I get the following error:The following disk images couldn't be opened:  Image: CentOS-7-x86_64-DVD-1511.iso  Reason: no mountable file systemsI would delete and download the file again but I don't have a stable and/or fast connection, so I would rather not do that as it is a real pain.Is there a way to fix this? I did some research online and didn't find satisfying solutions. My first thought was perhaps the file is corrupted due to my bad connection but it seems to be a common problem, so perhaps it isn't that?
How do I install CentOS?
centos
To install centos you needA virtual machine for try Centos,on Mac os you can tryvirtualbox or parallel.Try directly on a pc,but will erase your current osor you can partition hard disk and get dual boot,or installon different internal or external hd(linux can run on usb devices,of course usb3,usb2 works but is really slow)Is impossible to run linux by click on dvd dmg/img!Maybe in the future...
