Installing Arch Linux on Thinkpad T440 with Windows 10

I usually use BIOS for installing Linux system. However, on this T440, a Windows is already installed in UEFI boot mode and I want to keep it. Thus, I decided to try installing Arch on UEFI mode. And actually, it turned out to be easier to use UEFI boot mode. You can see whether you’ve enabled UEFI mode on boot setting or simply type the command when you boot into your Arch iso.

And it’s very easy to make an Arch bootable USB disk. Just download it   on another computer and run the command:

with sdx to be your USB disk (e.g. sdc, NOT sdcY)

Then let’s start!

When you boot into your Arch iso, connect to wi-fi first using wifi-menu. Then partition your disk with fdisk /dev/sdx. type d to delete partition, type n to add partition. After that, formating the root partition using ext4.

The EFI partition is already generated by Windows with name “EFI system” in fdisk -l. So we just leave it there.

Now let’s mount root and boot partition.

Then we can start installing the system, simply use:

And then generate fstab:

Now we have the new system, arch-chroot into it to configure everything!

Next, add a main user.

Make it a sudoer:

Install Yaourt, a package management tool to manage packages from AUR:

Add finger print authencation support:

Now the new system should be dual-bootable.
