I have an toshiba sattelite c50. It won't boot any longer from any bootable device (hdd, (intern, extern)cdrom, usb)
All the bootable devices are MBR partitioned and work on other laptop/pc.
situation before problem occurs:
- (bios settings) See images for my bios settings>
security tab https://ibb.co/jFvPcm
power mngmnt tab https://ibb.co/jSe6q6
advanced tab https://ibb.co/bDu6q6
advanced sub menu https://ibb.co/kvfeA6
Mainoverview (seems to be oke, just an overview)
Boot menu in bios (recognizes all devices internal, external)
Boot menu retrieved after hitting F12 (while booting) is oke, can boot from any device.
Hdd with xen hypervisor for test purposes (running 2 fedoras) Perfect booting without problems.
Till now (yesterday): i wanted to boot as normally my laptop but now he doesn't boot but give me an message "No bootable device -- Please restart the system".
New RAM memory tried from another laptop and reverse -> retrieve same error
i try an live linux usb and an internal, external cdrom to boot but --> same error
- To see if any hardware is broken i pulled out any hdd, cdrom and boot only from usb but --> same error.
- hdd and usb tested on another laptop an pc --> boot perfect, devices oke.
- Battery and bios battery pulled out for a whole night, i resetted bios settings via bios interface but --> same error.
All the hardware is well recognized in the bios.
Boot menu retrieved after hitting F12 (while booting) displays the boot-devices menu and when i entered an boot device the 'boot menu page' just refresh and do not boot.
I dont know what to do with it anymore. Can anyone help me with this issue?
