How to put lilo in the MBR and make my system dual bootable

micflunu · 12-27-2012, 01:15 AM

Ok!! sorry for that!!And I did everything u told me but it the same as before.To add some info about what is going here is some of the things that it is displaying.

Code:

Starting Network Manager... 
 touch: can not touch:/var/lib/sudo :Read-only file system
 touch: can not touch:/var/lib/sudo/mic/4 :Read-only file system
 touch: can not touch:/var/lib/sudo/mic/3 :Read-only file system
 touch: can not touch:/var/lib/sudo/mic/0 :Read-only file system
 When it has finally finished booting, I am provided only with a TTY. I can log in and cat my files, but I cannot write to any files or use any programs.

There's something wrong with your installation, could you please describe in detail what you've done in order to make Ubuntu run on vbox?

Did you anything other than the defaults? (besides installing lilo instead of Grub)?

oooo Markus!!I installed it a very long time ago!!I did not do any thing unusual. But if u want to check it out here is how I installed it.

Code:

sudo su
apt-get install bcc iasl xsltproc xalan libxalan110-dev uuid-dev zlib1g-dev libidl-dev libsdl1.2-dev libxcursor-dev libqt3-headers libqt3-mt-dev libasound2-dev libstdc++5 linux-headers-`uname -r` build-essential
cd /tmp
wget http://www.virtualbox.org/download/1.3.8/VirtualBox_1.3.8_Ubuntu_edgy_i386.deb
dpkg -i VirtualBox_1.3.8_Ubuntu_edgy_i386.deb

And as for grub it was installed for me as default with ubuntu 12.04.

Well, I'm getting more confused

What you discribed above is how you've installed Virtualbox? But isn't this a very old version? and now you're running a recent version of Ubuntu on this old vbox-version? Well, it's most likely that this doesn't work.

What's your host operatingsystem? also Ubuntu? which version?

Markus

micflunu · 12-27-2012, 03:22 AM

ya ubuntu 11.0.

markush · 12-27-2012, 03:27 AM

Well, 11,0 seems ok, but the recent version of Virtualbox is 4.2.6 and you have 1.somewhat.....

I would recommend that you upgrade virtualbox at first to the recent version. Afterwards you can try to find out what's gone wrong. But why do you install Ubuntu as a virtual machine on Ubuntu? And the threadtitle says something about dualboot?

I'm more and more confused

yes my host is ubuntu 11.04.But also I have been searching the net and I got the idea that this the error could be connected with the line

Code:

/dev/sda1 / ext4 errors=remount-ro 0 1

in my /etc/fstab file.I don know what is wrong

markush · 12-27-2012, 03:31 AM

I've already posted a fstab file which hasn't this entry, you should substitute

Code:

errors=remount-ro

with

Code:

defaults

and then reboot.

micflunu · 12-27-2012, 04:09 AM

I just didn't want to mess up my main system with out knowing what i am doing.I did the change with /etc/fstab but no hope..........

markush · 12-27-2012, 04:13 AM

mh, please explain what you want to achieve. You have Ubuntu 11 installed on your computer, and you have tried to installed Ubuntu 12.10 on Virtualbox. And what do you mean with "I just didn't want to mess up my main system...."? messing up while doing what?

Markus

micflunu · 12-27-2012, 04:38 AM

i want to make my main system two have two kernels.It has to boot with both kernels using kernel.It is part of my OS assignment.So I thought i will practice doing so until i get it right then do it on my main system.Well i used ubuntu 12.04 because it was now available for me.So did u get me now????

markush · 12-27-2012, 06:07 AM

With "two Kernels" you mean that you have one os (Ubuntu) and can select which kernel it boots? This is quite simple, I have this with Slackware, here as an example a part of my lilo.conf

Code:

# Linux bootable partition config begins
image = /boot/vmlinuz
  initrd = /boot/initrd.gz
  append = "resume=/dev/sda9"
  root = /dev/sda5
  label = Slack64-current
  read-only
###
image = /boot/vmlinuz-3.5.4-huge
  root = /dev/sda5
  label = failsafe
  read-only
# Linux bootable partition config ends
# Windows bootable partition config begins
other = /dev/sda2
  label = Win7
  table = /dev/sda
# Windows bootable partition config ends

I can select between the generic kernel, the huge kernel and Windows 7

micflunu · 12-27-2012, 06:35 AM

Yes tanks!!Except my lilo configuration can not even boot the first kernel correctly.It only gives me a tty prompt ,i can not run any of my application programs.

Code:

Drive / is not ready yet or is not present.Continue to wait ,or press S to skip mounting or M for manual recovery

and then every thing is rad only file system even when i run

Code:

sudo apt-get update

Displays a bunch of errors

markush · 12-27-2012, 06:37 AM

Did you install the vbox guest-additions? (on Ubuntu on vbox).

Markus

micflunu · 12-27-2012, 06:46 AM

sorry what is vbox guest-additions?
