VMPlayer can be very useful, especially for trying out Linux distributions, but while there are lots of the different distros. on the VMWare website available for download I already had a few iso files of Linux hanging out in my documents, but VM Player cannot open straight .iso files, it's run through a .vmx file which executes the .iso file, so you need this vmx file to boot up the .iso file....

Software:
VM-Player (free)
--downloadable from here
Notepad(or other basic text editor)/Kate
Any *.iso file
A .vmx file (there is one available to download here ("resul.vmx"))

resul.vmx
Download

Step 1: Editing the .vmx File

I downloaded DSL (Damn Small Linux) from the VM-Ware website just to try the player out when I noticed that all it was was a plain *.iso file with the *.vmx file, double click the *.vmx file starts up VM-Player and then boots the *.iso .

A lot of files can be edited with notepad (or similar program) including this vmx file...

-Right click on the *.vmx file and choose "open with">"notepad".

(Second Pic.)

The ninth line is the only line of text that needs editing, this tells the player what *.iso file to open for booting....

Now put the *.iso file you want to boot into the same location as the *.vmx file, mine are all on Desktop. Select the *.iso file you want to boot (in my case Fedora Linux) then press F2>Ctrl+C which copies the files name. ;-) then you can just un-select the file. (Picture five)

Now go back to Notepad and select the File name, Do not select the quotations too >Refer to image four. Then press Ctrl+V which will paste the file name you copied earlier.

Step 2: Save.

Next step is the save the file, Notepad, File>Save As, make sure you save the file type as "All files" and the file name has .vmx on the end. Also make sure it is saved in the same directory as the .iso file you want to boot

Step 3: The Proof of the Pudding Is in the Eating.

Next thing is to test it see if it'll work.....

Double click (default on windowz) the edited *.vmx file which *should* then start-up VM-Player....
