Installation in Non UEFI / Legacy BIOS System
Here's my experience installing Archlinux in Laptop (Non UEFI):
Toshiba Satellite C640
I installed Archlinux on this laptop, still using Core Image Media. And for the tutorial as follows. (No need to follow the tutorial below, it has expired) The following tutorial is just for documentation.
How to Install Archlinux 2011 Core Image
This laptop has been installed archlinux for a long time, starting from 2011 to 2018. But in early 2018 this laptop was damaged and can no longer be used. The hard disk that has been installed with archlinux is removed from the laptop. Then I use it as an external hard drive and boot archlinux in my latest laptop "Toshiba Portege R30-A." to continue a "rolling release model.." :D
Dell Inspiron N4110
For dell Inspiron i'm using the latest guide from arch wiki. And here's my documentation:
How to install archlinux Net Install
On this laptop archlinux has been installed since 2013. And it is still used today and the system remains updated. So it's been around 5 years.
Toshiba Portege R-30
This laptop is my main laptop for work. Therefore, I can't do the experiment for installing Archlinux on this laptop. But I have a Toshiba C640 HDD that is damaged, and I changed it to an external HDD, I'm happy that i can still run Archlinux on the Toshiba R30 using an external HDD (booting via external HDD without any configuration, boot and run). And what's on the old laptop all goes well on this Toshiba R30.
UEFII have a UEFI laptop with only Toshiba Portege R-30 A, but because this laptop has the Legacy Bios feature, the installation process is the same as non-UEFI. However, I did not install archlinux in this system, but booted archlinux using an external hard drive.
