Modify Boot Partition


So, I created a boot partition and made it bootable and got Ubuntu to install into this boot partition. When I try to mount it to modify it, it says "permission denied". I'm assuming I must've missed some step like taking ownership of it? Or worse, screwed up the install.

I basically created a separate partition for GRUB so I can install multiple distros with (hopefully) less headaches.

Any ideas would be appreciated!

Are you using sudo in your commands?

Sorry, I should clarify, I can mount it fine but trying to CD into it (so I can start modifying) it gives me the permission denied. Weirdly enough, if I do a sudo dir/ls command it will display Lost+Found (or something like that) but if I try to do it without sudo, it also says permission denied.

You could try "sudo su" without quotes at command line. Should be prompted for your password and then be able to do whatever.
Also gksudo or sudo nautilus are worth trying.

Make a directory to mount the /dev like

sudo mkdir /mnt/sda1

sudo mount /dev/sda1 /mnt/sda1

sudo cd /mnt/sda1


sda1 is an illustration of your partition, You will need to use what ever your partition number is. The directory name can be anything you want. Do not use a name of any other /mnt's.

I use the device number for a name. It makes it easier for me to remember.

You will need to build two more directories /boot/grub
and then the file grub.cfg if you installed in a different partition or copy the file from your distro.

yep, basically what I done and got the permission denied error while trying to cd in. The commands I typed were:

Code:
mkdir /home/user/test

sudo mount /dev/sda1 /home/user/test

sudo cd /home/sda1/test
I'm not sure if not having it in the mnt directory is causing the issue, but I'll try that when I get home.

Also your 'cd' entry is not the same as your mkdir.

Did you put grub inside your home partition? If not then do not use the word /home for the first word in the directory. When you change directories it will try and take you to the home directory.

yeah, that was a typo :P I'm a little off my game today..

During the Ubuntu install I selected sda1 as the partition to install the boot loader on but I did't select it to load as /boot if you get what I'm saying. Though, looking at the boot dir, I see a grub dir in their with a grub.cfg (going off the top of my head atm, not on my pc).

In your initial post, you say you created a separate /boot partition and installed Ubuntu into this boot partition?? The purpose of a boot partition is to have the boot files not an operating system? Also in this initial post you indicate you created a separate partition as a Grub partition. Is this a different partition or are you referring to the same /boot partition?

In your last post, you indicate you selected sda1 as the partition to install the bootloader for Ubuntu to. If you did that, what bootloader do you have in the master boot record from which operating system so that you will be able to access the Ubuntu bootloader?

Maybe you should download and run the bootinfoscript at the site below and post the results.txt file here:
