Naively, I bought a new Lenovo i7/6GB/1TB because it was cheap *and* it was one of the few laptops in the entire store that would still boot Linux from a usb drive without jumping through unknown hoops. All the others I tried with similar specs (many better laptops and all also with uefi boot) had some problem booting from usb - usually no 'legacy' boot setting or equivalent in the boot screen (no longer called BIOS settings). It came with Windows 8, which I assumed could not possibly be as bad as what it was said to be. Boy was I wrong.
Windows 8 is absolutely, abysmally, shockingly awful on a keyboard laptop. I have installed Classic Shell to give me back a start menu. I have learned to use ctl-alt-tab to get between the awful rubbish 'apps' and a quasi-desktop experience. I worked out how to get a command prompt. It's still only just bearable. I want this shit gone. Dead. Buried.
I had a talk to a guy in a small pc service shop - he says he gets at least two requests a day from customers begging him to remove Windows 8 and install Windows 7, but he tells me it seems it isn't possible on some new laptops to do this. He took a hard drive out of one machine, wiped Windiows 8 and installed Windows 7. When he put the hard drive back in the laptop, the motherboard would no longer recognize the drive. Perhaps he doesn't understand UEFI boot, I dunno. I am just tempted to send this shit back to Lenovo and say: give me my money back or give me Windows 7 on this machine.
