Hallo nichos, As MilesAhead stated i think the Linux ubuntu is probably the best option it is only about 7mb file.
I use Macrium on all my machines. I havnt had to use it with Vista but i have successfully restored Windows Seven once & Windows XP three times each time without any problems during the restore or afterwards, i cant fault it.
Each time i just insert the CD and restart my computer & it will take you to the Recovery options.
One of our members kindly put together a small tutorial for Vista Forums & Seven Forums. I have attached links that you can click on & they will take you to them.
I think these Tutorials will best answer your questions
The one at Seven Forums has a lot of feedback that you may find of interest. I hope this is of some help; Image your system with free Macrium Image your system with free Macrium - Windows 7 Forums
