Once you have either created the CD/DVD or flash drive, start up the problem computer. Watch your screen for the "boot menu" option, and press the corresponding key as soon as you see it.
Select the appropriate device (USB/Flash) or (CD/DVD) and move it to the first position using the + or - keys.
Press <F10> and confirm to save and exit.
The computer should now restart and attempt to boot from the device you have selected. It will take a few minutes, but you should be presented with a screen asking you for a name, to set up your network, and a couple of other basics.
:step1:Once the Ubuntu desktop has loaded, you should see a folder icon on the left panel. Click on that to open up a window that is most likely within your Ubuntu user directory.
Now, along the left side you should see a Devices
section. Under the devices section, you should see your laptop's hard drive with a size indicated beneath it.
Click on the hard drive to open it up in the explorer.
Navigate to C:\Users and select the user account that you have your data saved under.
You should now be able to view your user data as it is stored on the hard drive. Insert your flash drive and open a new window.
Once you have clicked on your flash drive in the Devices
section, you should be able to click and drag your data to the flash drive. Note that you can use CTRL+click to select multiple non-consecutive files, and Shift+click to select multiple consecutive files (all inclusive).
