Brand new Toshiba Satelitte L40D-B Model: PSKRGC-002001 Windows 8.1 pre installed 64 bit AMD A6-6310 APU AMD Radeon R4 Graphics RAM: 6144 MB Clock: 1.80 Ghz HDD Toshiba 686 GB Bios 1.00 English Trying to install Ubuntu14.04.1 from usb stick (tried several different sticks, checked them) This is a maintream laptop. I have already install numerous Ubuntu and other distros. I tried Fedora 20 and Ubuntu 13.10 on this computer with the exact same result: I have no other computer available, and no cd/dvd
I tried to install with secure boot and UEFI on at first, then turned off secure boot then turned off UEFI
With secure boot and uefi on, the install strarts, then a grub screen asking me to choose between live, install, oem install and check for disk defects. I tried them all repeatedly. The screen goes dark and after 10 seconds, the computer reboot. with secure boot off and uefi on, same thing with both swcure boot ad uefi off, first i could go to the language page of the install. Choose english. Then same thing. The computer reboots. I switched live usb creator (windows) for unetbootin to make usb stick. Same thing except unetboot screen (blue) instead of grub (dark) I tried then to partition HDD with windows. Same thing.
