fedora 17 freezes at loading screen at CD-based installation

[makhzanji]

I'm trying to install F17 on my laptop (Toshiba A-665 ... 4gigs RAM, nividia gforce GTS350M,core-i7 1.7 GHz processor), but the liveCD boot freezes about 3/4 of the way through the loading icon... EVERY TIME. I've checked the image, the LiveCD (using Fedora 17s own media checker) and re-downloaded / rewritten the ISO about a thousand times now. Conclusion: the ISO is fine, the media is fine. The Fedora live environment just WILL NOT BOOT, i even tried to install other Distros of linux (Ubuntu 12.10, Opensuse 12.2) and both of them gave me the same problem exactly.

To clarify:

I turn on my laptop push F12 to select CD\DVD as boot device Fedora boot options appear hit enter on the first option screen flashes white-ish, little cursor at top left (about 3-5 seconds here) little icon appears on screen, starts filling up ~3/4 of the way through, the icon stops filling At this point the the CD Drive stops spinning, as does the disk-usage light on my laptop. And i can't open the DVD Drive tray, with no response AT ALL. No "could not find this, that, or the other thing" errors. No response at all from the keyboard, I have to hold down the power button to reboot.

I get exactly the same result (with different progress bar) when I select "Trouble Shooting" and then "Boot in something-or-other graphics mode."

please help !!

Does your computer have an Intel on-board GPU as well as the nVidia one? If so, you will need to disable it in the BIOS first. This is a common laptop problem these days. I have a Lenovo with both Intel and nVidia GPU's - works fine with Windows (uses Intel for most stuff, and nVidia for high-performance graphics), but for Linux you have to disable the Intel GPU in the BIOS since Linux doesn't yet support that dual GPU configuration.
