How to Install GRUB on Arch Linux (UEFI)
|
||
======
|
||
|
||
|
||
|
||
Some time ago, I wrote a tutorial on **[how to reinstall Grub][1] on Arch Linux after installing Windows.**
|
||
|
||
A few weeks ago, I had to reinstall **Arch Linux** from scratch on my laptop and I discovered installing **Grub** was not as straightforward as I remembered.
|
||
|
||
For this reason, I’m going to write this tutorial since **installing Grub on a UEFI bios** during a new **Arch Linux** installation it’s not too easy.
|
||
|
||
### Locating the EFI partition
|
||
|
||
The first important thing to do for installing **Grub** on **Arch Linux** is to locate the **EFI** partition.
|
||
Let’s run the following command in order to locate this partition:
|
||
|
||
```
|
||
# fdisk -l
|
||
```
|
||
|
||
We need to check the partition marked as **EFI System
|
||
**In my case is **/dev/sda2**
|
||
|
||
After that, we need to mount this partition, for example, on /boot/efi:
|
||
|
||
```
|
||
# mkdir /boot/efi
|
||
# mount /dev/sdb2 /boot/efi
|
||
```
|
||
|
||
Another important thing to do is adding this partition into the **/etc/fstab** file.
|
||
|
||
#### Installing Grub
|
||
|
||
Now we can install Grub in our system:
|
||
|
||
```
|
||
# grub-mkconfig -o /boot/grub/grub.cfg
|
||
# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
|
||
```
|
||
|
||
#### Adding Windows Automatically into the Grub Menu
|
||
|
||
In order to automatically add the **Windows entry into the Grub menu** , we need to install the **os-prober** program:
|
||
|
||
```
|
||
# pacman -Sy os-prober
|
||
```
|
||
|
||
In order to add the entry item let’s run the following commands:
|
||
|
||
```
|
||
# os-prober
|
||
# grub-mkconfig -o /boot/grub/grub.cfg
|
||
# grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
|
||
```
|
||

||
