I bought this Lenovo Thinkpad 540-T (64-bit) a little over a year ago. Had I known all the obstacles EFI was going to throw in my face, I never would have. I didn't want Windows, I wanted Ubuntu and installed 14.04. Somehow back then, I made a mistake, I don't evwanten remember what it was, and wiped out the Windows boot. I didn't mind that too much, I hated Windows 8.1 and never wanted to use it. I could still boot Ubuntu and things were ok. They stayed okay until kernel 3.13.0-48 came out. With this kernel, my USB and WiFi were broken. I then made the mistake of installing grub (v1) and this at least allowed me to boot up the previous kernel 3.13.0-46 which worked fine.

I wanted to get beyond this state today, and a helpful fellow on X-Chat Ubuntu told me to reinstall grub2-EFI, which I did. Probably I should have told him about my screwed up EFI configuration, but I didn't. The result now is that whenever I reboot from the hard drive EFI comes up with a nasty "Secure Boot" message telling me that my disk image is unrecognized. I was able to boot from a CDROM, which is how I'm here now, but I don't have access to my hard drive. I've also made a bootable startup stick from that CD using "Startup Disk Creator", but I want access to my hard drive. Will there be a way to configure this USB stick as a boot device that will allow me access to my system as it was. Or am I going to have to pull all my data off and get the hard drive reloaded with Windows and start all over?

Never mind! Just turned off Secure Boot in the BIOS and everything is fine!
