I'm trying to install Ubuntu on my Windows 7 x64 computer with an USB flash drive.

I have put the Ubuntu 12.10 desktop amd64 ISO on my USB flash drive using both Unetbootin and Universal USB Installer and it works out just fine.

Restarting the computer, open my BIOS and boot from USB/put USB as first booting option, Ubuntu starts booting its installation GUI. Everything goes fine, I continue with the installation but when I come to the "choose how to install" I choose "Install Alongside of Windows 7" and press reboot to continue.

Then here's my question what's supposed to happen then? It reboots and then goes into Windows like nothing ever happend?

If I choose boot from USB again/if I had put it as primary boot option, I just comes to the installation GUI again, the same as before, not what password do you want or it starts installing but the very first Run from the CD or Install Ubuntu options again.

How do I get it to continue with the installation?

To clarify a bit more: It doesn't reboot unexpectedly but after the same step every time. So it doesnt start to install anything at all.

"Install Alongside of Windows 7" and press reboot to continue. - this should not be steps following up each other. What happened in between? The actual installation should happen rather than reboot before. – gertvdijk Jan 21 '13 at 16:51
@gertvdijk Before that everything was just normal, as it should be. With the install ubuntu then "Prepare to install Ubuntu", then "Set up wireless" (or sometimes I skip that step or I already connected using the normal connection menu) then I come to "Allocate drive space" and press Install alongside of Windows and then it reboots. – Osyx Jan 21 '13 at 17:07
