So a .iso is currently downloading onto my flash drive. After that, what do I do? I'm just scared of deleting Windows 7 and all my files.

Hi, David. I will need to know what you want to do. Do you want to create a bootable USB drive with Ubuntu 11.04 in it? – JohanSJA Aug 4 '11 at 6:41
You may find this answer helpful. Before you proceed please make a full backup of your windows installation. – Takkat Aug 4 '11 at 6:47
I have a USB 2.0 4GB flash drive. I have a laptop running Windows 7 which has a bunch of important files. I would like to install Ubuntu 11.04 "the proper way" by dual booting it. I install the .iso file from onto the flash drive. When I open the file, it gives me an option that I don't understand (I'm brand new to Linux and CD/USB burning and what not in general). I do know the flash drive is G:... – David Aug 4 '11 at 6:55

If anyone could help me, I'm getting very frustrated :D – David Aug 4 '11 at 7:08

Go to ubuntu dowload page and follow their, very clear, instructions (There is a big red button there, ``show me how''). If you want to do something a little bit more exotic tell us what you want to do.

Awesome, I wasn't aware of those "show me how" thingies - very nice. – Sergey Aug 4 '11 at 7:43

You're doing it a bit wrong. You shouldn't copy the ISO file to the flash drive - you need to use some program to "burn" that iso file to a CD or to a flash drive. Burning a CD seems to be a bit easier than preparing a flash drive - for the latter you'll need to somehow "open" the ISO image and extract usb-creator.exe program from there, so you'll need some software to work with ISO images anyway. Windows

Then you'll need to reboot your machine, enter BIOS setup and choose your flash drive/CD as the first boot device. Then you reboot with the usb drive/CD inserted and you get to the "live" ubuntu environment, from where you will be able to start the installation process. The installation process should be easy even for an inexperienced person - there are just 6 or so questions. And it won't erase your files unless you explicitly tell it to remove the Windows partition.

Having a backup of your important files is a good idea in any case, even if you weren't installing Ubuntu.

Another thing to mention - you could install VirtualBox and practice installing Ubuntu inside a virtual machine first.

Also, you could order a CD from if you still having trouble with preparing a usb drive
