this forum is my last chance. I have a Acer Aspire X3470 and I am trying to boot ubuntu live USB. I already tried to boot from the Ubuntu desktop image 12.10 and 13.04 but with the same result. When I boot my pc I see the grub menu and I select the first entry for booting without installation. After that I see that my USB device tries to read some data (I see it on the led) and then it stops reading from the device. Afterwards nothing happens and all I see is a black screen.
I already tried the following boot parameters with no result:
- delete the quiet and splash entries
- nomodeset
- xforcevesa
- vga=normal
- radeon.modeset=0, radeon.modeset=1, i915.broken=0, i915.broken=1
- acpi_osi=Linux, acpi=off
- acpi_backlight=vendor
My PC has the following properties:
- Windows 8 pre installed
- GPT
- Acer Bios (newest firmeware)
- Secure Boot, Legacy boot
I already tried all kind of combinations for secure boot and legacy boot and I disabled the fast boot option. After selecting the grub menu entry the menu disappears and everything I can see is my black screen (but the screen device is on just as the backlight) nothing more. I tried to force grub to be more verbose and to show me what he is doing but with no success. I have no hint what happens in background and why ubuntu is not loading.
I copied the ubuntu desktop images with win32 disk imager, unetbootin and usb live creater always with the same result :-(
Thanks in advance
@Solved: Hello I solved the problem. The usb stick was formated with fat and should be formated with fat32.
