Hello guys,

I had Toshiba Satellite with windows 8 installed.I need to install ubnuntu from usb, so changed the windows advance settings like

security booting: disabled
booting mode: changed to CSM
Boot : USB first

Now my problem is:

I can't access the windows or BIOS.I can't boot from USB with ubuntu.I cant see event the TOshiba logo screen.All i can see is :

Check your cable connection,NO bootable device

Please help,
Thanks
