Set Arch Linux as default Grub Entry and stop loading Grub prompt

arghya · 2016-05-19 16:16:14

I have Arch Linux installed in sda2 while my grub is installed in sda1.
Whenever I boot, I’m sent to the Grub terminal with the 'grub>' prompt.
To boot into Arch, I use the following commands:

set root=(hd0,1) 
chainloader (${root})/efi/arch_grub/grubx64.efi
boot

This boots to the default Grub Screen from where i can choose Linux or Linux-LTS and then it boots into the system.

It is quite inconvenient to type these commands every time I boot. How can I boot into the Grub Screen directly as it was in the beginning?

P.S.- I’m using UEFI boot mode and GPT partition.

Why have you installed GRUB to a partition?

This is not recommended, see https://wiki.archlinux.org/index.php/GR … nless_disk

Please list the exact commands you used to install the bootloader to the disk.

Please also post the output of:

# parted -l
# efibootmgr -v

These commands can be run from any GUN/Linux live ISO image.

Have you seen https://wiki.archlinux.org/index.php/GRUB#UEFI_systems?

I don't remember the commands used to install as it was quite a while ago. But I can say I followed the wiki.
sda1 is my efi partition, that's what I meant to say. I had installed the grub in sda and not sda1 most probably as it used to work till yesterday.
I beg your pardon as I find UEFI very confusing.

Please also post the output of:

Is there any way I can get the output of these within the installed OS? Else I'll have to make a live ISO image again.

Of course. I read it all before posting in here.

You can run the commands from the installed system as well if you want.

These are the output of the commands.

You need to:

# pacman -S efibootmgr

Then try again:

# efibootmgr -v

Here's the output:

[arghya@Antergian ~]$ efibootmgr -v

efibootmgr: Could not parse device path: No such file or directory
Boot2001* EFI USB Device

As far as i understood from the output, It seems to contain the path of Windows and Ubuntu efi files. Both of the OS doesn't exist and that's why it goes to the terminal. How can I add the EFI file of my current OS in the menu and delete the others maybe? Or do i need to do something else?

Install GRUB to your hard drive.

See https://wiki.archlinux.org/index.php/GR … allation_2

To answre your question, have a look at /etc/default/grub

GRUB_DEFAULT=0
GRUB_TIMEOUT=25

should be the interesting one
