How to edit /boot/efi

Question

I have installed rEFInd, and it works well enough, but I am trying to add a theme. To do so, I need access to the /boot/efi/ folder. When I try to access it, I get the following error:

rufio1337@BattleStation:/$ cd boot/efi
bash: cd: boot/efi: Permission denied

(As sudo):

rufio1337@BattleStation:/$ sudo cd boot/efi
sudo: cd: command not found

In the GUI it shows the folder with an x on it.

Anybody know how I can get access to this folder?

Running fdisk -l gives me the following:

I would also like to point out that I am veeery new to Linux, so child-speak is appreciated! — Zach Dahle, Jul 19 '15 at 19:29
cd /boot/efi is correct. But if you are new, I do not recomment to start with efi themes ;-) — Pilot6, Jul 19 '15 at 19:37
What version of Ubuntu. They changed the mount in fstab from defaults to umask=0077 which locks it. I had to change back to defaults. And just remounting did not work. I had to reboot. sudo nano /etc/fstab — oldfred, Jul 20 '15 at 03:34
Not a duplicate but related to 1st problem Why doesn't sudo cd /var/named work? — Warren Hill, Jul 20 '15 at 15:12

You can't use sudo with cd. To get into protected directories, you can type

sudo bash

To get a root login shell or type

su -

To log in as root in your current shell. The behavior of both is identical, the back end differences won't matter much for what you're doing.

Sorry if this is necro'ing your question but an alternatively way you could do this is with gnome-system-monitor

In the terminal type sudo gnome-system-monitor which will open a gui that shows running processes, active resources, and file systems.

Click file systems then open the /boot/efi

Since the gui was opened with root permissions, the file window is granted root permissions as well.

You can edit files you need or you can continue your journey with root privileges by right clicking the window and selecting open in terminal.
