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.
- Are the BIOS settings I intend to make OK for installation of Ubuntu?
- Will the performance and/or stability of Ubuntu be affected by not using UEFI and Secure Boot?
- 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?
- 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...
