I have a Alienware M14xR1 with 16 gigs of ram and nVidia GT555M with Optimus + Intel HD3000.
I installed my Ubuntu from a USB stick to another USB stick. Did not use the startup disk utility, and literally installed it on the USB stick after wiping it with diskpart in windows. I have a need for Installing Ubuntu on USB, not a LiveCD Startup disk or installation on the HDD.
When I try to boot it normally, it won't boot. No boot splash screens, no reports. No crashes, or something. Just a plain black screen. However, LiveCD USB would boot well.
I put into some efforts with trying some answers in the community, such as appending nomodeset to grub parameters, appending "console=tty1 acpi_backlight=vendor acpi_osi=Linux". I tried CTRL+ALT+F1-6 after some time letting my notebook to boot, and no signs.
I also tried booting into GRUB screen by holding SHIFT on boot, but it just shows "GRUB LOADING." and stops there.
Is there probably a solution for solving this problem and letting me into booting Ubuntu?
P.S. I have succeeded booting into Ubuntu in my USB using VMWare before, so I'm suspecting on my hardwares.
EDIT: I'm using Ubuntu 12.10.
