Windows 7 won't boot 'No bootable device'original title: Windows 7 won't boot after forced shutdown. I recently got a new laptop (Lenovo Idea. Pad y. 55. 0p, in case it's relevant) that came pre- installed with Windows 7 home premium 6. It's been fine and problem- free, until this morning. It booted fine, logged in fine, connected to the internet fine, then. I was checking my e- mail and I had to do a forced shutdown. When I turned it back on, it displayed the Lenovo logo fine, but then the screen went black and gave me this message: "PXE- E6. Media test failure, checkcable. PXE- M0. F: Exiting Broadcom PXEROMNo bootable device - - insert boot disk and press any key"The problem here is that I can't do that, as my laptop didn't come with any sort of disc (not sure if it's supposed to, but I didn't notice until now so it's a bit late to fix that). So, what can I do?
