Theres some good tutorials on this subject area at http://www.pendrivelinux.com/

The relevant tutorial for 7.10 is at http://www.pendrivelinux.com/2007/09/28/usb-ubuntu-710-gutsy-gibbon-install/

You will need at least a 1Gb memory stick that you can empty of all data.

You can also run Ubuntu from inside a "virtual computer".
Take a look at InnoTek's Virtual Box - http://www.virtualbox.org/ Or Microsoft Virtual PC - http://www.microsoft.com/virtualpc/ Also check the Ubuntu Wiki for issues with MS Virtual PC https://help.ubuntu.com/community/HowToConfigureUbuntuForMicrosoftVirtualPC2004.

Virtual Box is probably easier for Ubuntu than VirtualPC. These are both about 20-30Mb downloads, and are free (zero cost) for non-commercial use. You will require a reasonable spec computer with at least 512Mb of ram and more than 4Gb of free hard drive space

It seems as if the "apt get" command needs a active internet connection. is there any other way to get the applications, maybe from another pc with active internet. I cant set up my internet seems as if hardware is not being detected, will work on this once i get the pendrive to work

if you download the following packages:

ftp://ftp.ubuntu.com/ubuntu/pool/main/s/syslinux/syslinux_3.36-4ubuntu5_i386.deb
and
ftp://ftp.ubuntu.com/ubuntu/pool/main/m/mtools/mtools_3.9.10.ds1-3_i386.deb

Instead of the apt-get install line, copy the files over, and use:

sudo dpkg -i syslinux_3.36-4ubuntu5_i386.deb
then
sudo dpkg -i mtools_3.9.10.ds1-3_i386.deb

The wget line will also want to donwload from the internet, just download the following file, and copy it over.
