I have a hp envy running Windows 8.1. I recently ran a system restore, and ever since it has run the hp logo, then gone to a black screen and stayed there. Things I've tried: Boot in safe mode: No change. Startup Repair: Said it couldn't fix it, but I can't get to the log file to find out why (is there a way to access windows explorer from the startup repair menu? Maybe using the command prompt?) System repair:Said there wasn't enough hard drive space. Another system restore: Didn't work, blamed my antivirus. (McAfee) Full system reset: Said there was a drive partition missing. Does anyone know what I could try to resolve any of these? I have access to everything in the startup repair menu(f11), as well as the BIOS, but I'm not really sure where to go from there.
