"The major problem for this laptop is that lenovo did only two partition one 25GB for drivers to store and another 884GB of C: drive . U cannot shrink the C drive , if u do this then the laptop would corrupt and the one key recovery which these lenovo laptop has at left side of power won't work and u should take to service center and they charge 1200 for re-installing ( which is not a part of warranty) . U cannot install Windows 7 due to drivers not compatible . Lenovo guys didn't gave any windows 8 disc.I tried to shrink the C drive but it corrupted , i then try to install windows 7 then it gave some error - "windows cannot install in gpt partition". So i fixed the mbr with live ubuntu on pendrive and installed windows 7 but due to drvier i cannot use webcam and wifi. And it only starts when pluged in and in battery it wouldn't . So i gone to lenovo service center and re-installed windows 8 for Rs. 1200."
Use inbuilt Windows Partition Manager. Go to Search, then search for "disk", click settings......there should be a "create & format hard disk partition" option
