This question already has an answer here:

Notebook Specifications: Lenovo G580 Ideapad (Model 20150)- with Win8 CPU i3-31101M, 2.4GH, 4GB RAM, Intel HD4000 GPU

I intend to completely replace Windows 8 with Ubuntu, and to avoid problems, to set up the BIOS to legacy compatible. Some of the BIOS settings I intend to make were not addressed in previous threads concerning this specific notebook. Hence this thread.


Security Menu: (1) Secure Boot [Enabled] change to [Disabled] (2) Reset to Setup Mode [Enter] - press "Enter" to clear PK, disable secure boot and enter setup mode.

Boot Menu: (1) Boot Mode [UEFI] change to [Legacy Support] (2) Boot Priority [UEFI First] change to [Legacy First] (3) USB Boot [Enabled] leave as enabled

Exit Menu: OS Optomised Defaults [Win8 64Bit] change to [Other OS]


Make a bootable USB stick using another Ubuntu system and attempt to boot up this notebook and and select Ubuntu to completely erase and use the whole HDD.


  1. Are the BIOS settings I intend to make OK for installation of Ubuntu?
  2. Will the performance and/or stability of Ubuntu be affected by not using UEFI and Secure Boot?
  3. Is there any need at all to use UEFI and Secure Boot in a single Ubuntu install (with no Win8)- if yes - what should the BIOS settings be like?
  4. Should I install 32Bit or 64Bit for this specific notebook, considering it has only 4GB RAM (probably shared with Intel HD4000 GPU)?

I'm a total nOOb! Please help...

Installed Ubuntu 13.04 from DVD drive. Problem with brightness and occasional crash screen. I couldn't resolve these issues, so I installed another distro. – Tim Jul 14 '13 at 20:52

This laptop works fine with Ubuntu 12.04.2 LTS.

Installed it from a cd/dvd

Shrinked the biggest partition (the standard windows 8 partition) and made room for it. Changed nothing in the bios except Boot Order (cd first, then ubuntu, then windows)

Everything seems to work just fine, even the special buttons.

Havent tested the cardreader or wired ethernet, but the eternet adapter is visible as a working adapter in linux.

My tip is to avoid non-LTS ubuntu releases, they are not stable.

Download latest Ubuntu 12.04.3 which comes with latest kernel and it will work brilliantly out of the box. Don't worry about UEFI and secure boot as Ubuntu installer supports it fully. If you want later you can add the Libre Office PPA and Glassen PPA to keep office and Intel driver to latest.
