Have a brand new Lenovo Y50-70 running Windows 8.1. Wanted a Ubuntu partition so that I can run Kerbal Space Program in 64-bit. download 64 bit image of Ubuntu 14.10 and pendrivelinux's Universal USB Installer to burn it into a bootable USB. Go into BIOS and set it from UEFI to Legacy and to check legacy first as well as check to make sure USB booting was enabled. Booted into usb nice and quick but it looked kinda glitchy so I ran Ubuntu's built in integrity checker. It said two files were missing/corrupted. Booted up back into Windows 8.1 no problem and ran md5sum's on both the Ubuntu iso and the Universal USB Installation program. Both checked out. Ran USB installation program again because I thought it might've been a fluke because I had a bunch of programs running simultaneously the first time around (thank the gods for 16 gigs of RAM) but I get the same glitchiness and the integrity tests says two files are missing/corrupted. Problem is this time around Windows won't boot no matter what, I've tried the auto-repair, I've tried system restore as well as setting the BIOS settings back to their factory defaults. Finally I got it to boot on safe mode with Networking. I ran the W7F Diagnostic tool and here are my results. Tried running CPU-Z but got an error dialog box reading 'The error code 0x43C (1084) occured during initialization. Do you want to display the error log file?' I've included that error log file as well. Unfortunately the RAMMon program failed to functioned as well giving the following error message: 'Unable to load Directlo driver Unexpected Error' Anyways I've been up today almost 11 hours so I'm thinking I'm going to sleep right now and let my antivirus do a full scan while I sleep to see if it picks up anything. For full disclosure this laptop has had trouble connecting to a wifi router as documented here -->>(hxxp: bit ly 1ubEIC8) Also I ran a full Malwarebytes Anti-Malware scan and came up with over a hundred false positives (some included registry keys) which I accidentally put into quarantine while I was unsuccessfully trying to Ctrl+A them so I could include them into the exceptions list all at once instead of one by one. I do enough of that mind-numbing work at my day job. I appreciate any help you can give me. I consider myself pretty tech savvy, but I always end up having to learn new things.
