I recently tried to install Ubuntu on my new Lenovo V570, planning to dual boot 11.10 with Windows 7. I realized after installing that it would boot straight into Windows, so I looked up the issue. I read something about UEFI, and found a page suggesting that I wipe the drive with GParted, installing a msdos partition table, and then install Ubuntu. (I tried linux mint first, because that's what I had on my flash drive at the moment.) I attempted this, and now I'm left with a computer that won't boot anything from the hard drive. If I install Ubuntu or Linux Mint 12 using either MSDOS or GPT, it simply skips the hard drive. My BIOS has no option to disable EFI, and I'll admit I know shamefully little about EFI or different types of partition tables. I'd like to know what I have to do to make my computer boot again.
