I have been unable to boot Linux from a USB on my acer aspire 5750G laptop It goes through the boot and then freezes half way through. it has done this with every type of Linux I have tried. Before anyone asks I have tried every single one of these boots on my desktop computer and they work perfectly every time. This freeze only happens on my acer aspire. I have tried it on a Toshiba laptop as well and it boots perfectly again. I have tried almost everything, I say almost because posting on a forum like this is the only thing I haven't tried. Please be clear I'm not concerned with installing it onto my laptop I just want it to run off a USB. Please I really want this to work.
Looks like a video driver issue. Select the nomodeset option (under F6) at the "Try/Install" screen. Skipping some of the video install stuff is possible by typing a character at the screen with the two little icons at the bottom (a keyboard and a little stick person), then select language, ... If that doesn't get you through, try one of the alterative installs which have even less video dependence. Once you are running, you can install the appropriate proprietary video driver, and maybe add nomodeset to the /etc/default/grub file on the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" line after the splash.
Have you tried choosing "the nvidia graphic card in the bios in order to use only the Intel integrated card (choosing 'integrated' instead of 'switchable')"?
