Hi,
I just installed Windows Insider 10 (the latest version as of 6.30pm 7th-June-2015 Sydney time). After prompts to reboot so it can complete the installation, it fails to load anything (see attached video).
The external HD that is in the video is a recovery disk for windows 8.1 (created immediately before the download). Unfortunaltely no UI shows so I cannot get into F8 mode to try and fix the problem. All the video, graphics drivers were up to date before
installation. This clip is <30 seconds but the laptop was running for nearly 24 hours before I gave it a hard reboot (press and hold power button, then recorded the video).
MY CD drive is broken and the company that I bought the laptop from refuse to take it in (it is still under warranty) so I cannot use the Windows 8 CDs to reinstall Windows :/
Thanks for your time
Matthew

Update:
Got the chance to try and run the BIOS tools on startup. The laptop in question is a Toshiba Satellite L850 pskg6a-00r00h. The manual says that F2, F8 (and some forum replies say shift-F8) are the keys tp
press for loading the BIOS menu on startup, but I follow the instructions to the word and nothing happens. I tried removing and placing the battery back in, removing the battery and running the power from the power cord, cleaned the RAM stick, checked the
voltage on the CMOS battery and nothing has changed from the original problem.
As a test I tested to see if StickyKeys would work by spamming the shift key 5+ times, which reacted as normal (the beeps).
Also tested if the laptop had defaulted to try and output to an imaginary second output (by attaching an external monitor to it and using the keyboard commands for switching outputs) and that did not do anything.
