I dont think you will, But i think we should go for it and try for an install, so here is what I would like you to try when you have your Iso on pendrive,
set the dell up next to the mac so you can follow this..
1, plug in the dell
2 insert usb into drive
3 switch on the dell and tickle F12 as it switches on [this should bring up the short boot menu]
look down the list and find usb click on it and enter, after a few seconds it should start to load to Ram, [you do not need a harddrive at this stage]
4,when it is loaded check everything works ok [wi-fi, sound, graphics] easyest way to do this is click on the wireless icon find your router and enter the password, when loaded go to your favorite music vidio site and pick something your familiar with, if it plays ok and the picture looks good you can then decide if you want to take a chance on installing.
5, double click the install button the iso will then check the components of your machine this may take several seconds to a couple of minuets, then provided the harddrive checked out ok it will start to install [if it fails at this stage the harddrive is probably shot]
watch it install when it asks about partitioning choose use complete disc, you will also be asked if you wish to install non-free/proprietary drivers tick the box for yes and enter
you will need to enter information as it installs so keep an eye on it, a typical linux installation can take from 10 to 20 minuets [far less than windows]
if it installs you will get a message do you wish to re-start now, accept
now sit back whilst it re-boots then it will take a couple more minets to clean up the installation and get rid of the install files,
then if all goes well we will have a working linux lappy
Sorry this is a long winded back to basics description but I am trying to cover as much as I can
[bed time is 23-00 gmt/utc] I will be about till then for more questions
