Hi dragas,


Welcome to Lenovo Community Forums!


As the Lenovo G580 that you have purchased which is installed DOS (Disk Operating System), below are the steps to change the settings in BIOS and then install the OS (Operating System) after formatting the Hard Drive:


  • Turn ON the computer, before Lenovo LOGO is displayed on the screen. Keep tapping on “F2” Key to enter BIOS menu - Note: To check how the BIOS menu looks and to explore its options Click Here.
  • Then in “Configuration” tab click on “SATA Controller Mode” and select “Compatible” option.
  • Now in “Boot” Tab click on “UEFI Boot” and Disable it.
  • Now Click on “F10” Key to save the changes that are done in BIOS and the computer will automatically restart.
  • Insert the Windows 7 OS Disc and it will initialize the process of installation.

Here are the steps to create a Partition with the Windows 7 Installation DVD; you can create a partition with the Windows 7 installation DVD:


  • Boot from the DVD
  • Click Install Now
  • At the setup screen, click Custom (Advanced)
  • Click Drive Options
  • Here you can create and format partitions
  • Setup the disk as you want it and make all your partitions now - NOTE: you should make the Windows 7 partition at least 30GB
  • Continue with install.

Hope this helps!!!


Do post us back if the issue still persists.
