Can't edit grub.cfg; Ubuntu will not save the file even though I use sudo
location: ubuntuforums.com - date: December 15, 2009
I'm trying to edit the grub.cfg file in /boot/grub/. I'm using the command:
sudo gedit grub.cfg
while in the appropriate directory. I removed the lines for the last two editions of Ubuntu, then I hit "save". I got an error stating:
Could not save the file /boot/grub/grub.cfg.
You are trying to save the file on a read-only disk. Please check that you typed the location correctly and try again.
I've made numerous changes to both grub and other protected files this way and never had a problem. What gives?
Dual boot win8 and Ubuntu, How to edit grub cfg?
location: ubuntuforums.com - date: February 19, 2014
Got a call asking for a dual boot win8 and Ubuntu on a rather old Latitude D430 laptop.
Quite simple: with a blank 80Gb Hdd, use win8 DVD delete all partitions and allocate 47Gb for windows, it automatically created a small NTFs partition for its bootloader (I guess). Leave 30 some Gb unallocated space for Ubuntu late.
After win8 installation is done. Boot with Ubuntu Live Usb,
1. Select install Ubuntu
2. Select Something else (custom installation)
3. Add ext4 partition 20Gb for /
4. Select partition / for grub install location
5. Create /home and swap partitions within a logical closure, that used up all the hdd space left.
6. When Ubuntu installation is done, restart the system and it automatically boots into win8 as if nothing done about Ubuntu.
This is because Ubuntu partition / is not active and nothing altered within window partitions.
7. Search on web, find no clear enough instructions about how to make a linux partition active for me. I boot the system with
a mac o
Update in grub.cfg file for loading new kernel image in Ubuntu 11.04
location: linuxexchange.com - date: August 22, 2014
I am new to Linux. I am compiling Linux kernel (ver: 188.8.131.52) in gcc in traditional manner in VMware machine in Ubuntu (kernel version - 2.6.38-8-generic) 11.04 version. I am unable to find, where to update about newly compiled kernel in the grub.cfg file. I updated the newly created image version name in the existing image. Then VMware didn't able to load new kernel. I have searched in internet but I didn't find. So anyone can help me, to update in the grub.cfg and to successfully load new kernel. Few things about what I have done:
Make bzImage to create image file.
Make modules_install && make install to install modules and then
sudo mkinitramfs -o initramfs.img-2.6.34 2.6.34. Then
sudo gedit grub.cfg. In that at the mementry I updated the version of vmlinuz and initrd from 2.6.38-8 to 184.108.40.206.
This is I have done.

upgrading to ubuntu 14.04, edit grub.cfg 'ro' to 'rw' everywhere?
location: ubuntuforums.com - date: December 16, 2014
I was upgrading my ubuntu 13.10 to 14.04 and was having this exact Ubuntu 14.04 doesn' t boot after upgrade from 12.04 installed inside Windows 8.1 problem, the sysytem was not starting after upgrading so as was suggested in the link, I entered the grub menu (holding down the shift key) then selected edit boot commands and changed the 'ro' flag to 'rw'. I have been able to start my system but it is a temporary work around and I need to edit my grub.cfg file to permanently set 'ro' to 'rw'.
I want clarify that should I change all the occurrences of 'ro quite splash' to 'rw quite splash' in grub.cfg? There are two places that 'ro quite splash' occurs in grub.cfg file. I also downloaded grub customizer because I read that you can edit boot commands and set flags more easily but I have not been able to work that out too.
I am very new with ubuntu. Please help.
Ubuntu / CentOS / Grub issue
location: linuxquestions.com - date: February 15, 2009
I've had Ubuntu installed on my system for awhile now and i recently installed CentOS. I elected to let CentOS install it's own Grub (probably my first mistake). After that, now I don't have an option to boot in to Ubuntu when I start the computer up.
What do i need to edit or change in order to get this back to normal.
Here's what i've got right now.
My original Grub.conf from Ubuntu. (note that the partition that says Ubuntu 7.10 was replaced with CentOS. Ubuntu 7.10 is no longer on the machine)
