(adsbygoogle = window.adsbygoogle || []).push({}); Hi everyone I recently has an issue with my Toshiba Satellite which was on windows 8.1. Basically I can't boot without it being in CSM and not in uefi I had to disable secure boot and all. I had also downloaded 8.1 on my usb drive as a recovery drive basically. Now I had installed it on the c drive but still am unable to boot it on uefi and on a secure boot. If anyone could help me with this issue that would be great thanks
