I bought this laptop in WHD and was skeptical at first, because there were many returns there and thus probably also problems. When the notebook is then arrived had to be installed into the operating system. Therefore you have the boot order in the BIOS (F2 click on startup) Change is what beginners do not very easy to find and also dare not zuändern something. Best places in the BIOS to UEFI yet, more on that later. After that was done I simply inserted the Windows 8 DVD, and after installing all the drivers that were installed on the CD from Lenovo. After Windows was first, but when I opened pictures always came there to freeze. Remedy procured because the BIOS update. Since I had previously asked to legacy support (ie normal BIOS) and after updating it has automatically set to UEFI, Windows did not start only. After I put it back on Legacy BIOS he has started normally and now everything works as it should.
