I have LENOVO Ideapad z570 model. when ever i try to install ubuntu(any version 12.04,12.10 or 13.04) it say "no operating system detected" but i have Windows 7 installed on it. And under the option "Something else" it shows whole 1 partition of 750GB hard drive but i have 2 partition. I tried to create new 10GB partition from that 750GB of partition and installed unbuntu on that 10gb of partition, it erased all my data and all the partition. What am i supposed to do to install ubuntu?

Did you boot the CD in EFI or Legacy mode? –  BeryJu May 10 '13 at 14:49
Legacy mode.... –  Syed Mohd Ali May 10 '13 at 14:58
try EFI mode, cause Windows is probably installed in EFI Mode aswel –  BeryJu May 10 '13 at 14:59
there is no such option. may because of old bios.. –  Syed Mohd Ali May 10 '13 at 18:24
ok then it seems like you have a BIOS and not EFI, so that's now sorted –  BeryJu May 10 '13 at 18:40
