So i decided to upgrade my desktop's ubuntu..
it had been rocking some version of Ubuntu 11 for a few years.. was time for a change. So i got the latest version (13.10) from the site,
burnt a live dvd and popped it in. nothing happend on boot! after a lot of fiddling i gave up on the live cd route, and decided to use a live usb. thats how i installed it on my Dell XPS earlier this year...
So i created a live USB.. and that didnt work either. Basically the motherboard was so old, it didn't support usb booting!
Since the wifi card was having issues i decided to try something i've never done before: Install Ubuntu directly from the hard drive.
Basically what you do is
1) copy the downloaded cd iso to a specific location
2) make an entry in GRUB2(this only works in GRUB 1.9 onwards) so that you can just boot the iso..
heres how you do it(required basic terminal navigation knowledge.. that i googled)
STEP1 - The Live CD is also known as the "Desktop Installer". It is the default Ubuntu installation CD. The ISO you downloaded has the name "desktop" in its name copy it somewhere easy to navigate to(later you'll need to type the address in terminal)
STEP2 - Copy CD/iso contents over to the system using the commands:
Replace the name of the ISO to whatever you downloaded and /dev/sda1 with whatever your new partition is(use system monitor to check the disk and partition names).
STEP3 - Edit your grub configuration file
GRUB1 users :
to edit the Grub file as root(so you can save your changes) run this
or
Edit your grub configuration file to boot from the new partition by adding the lines
the first line after the title tells grub which partition contains the installer. hd0 stands for "first hard disk," and the 0 following it standards for first partition. You will need to change this if your installer partition is different from /dev/sda1. sdaN becomes (hd0, N-1), sdbN becomes (hd1,N-1) and so on. As you can see, grub starts counting from 0, which can be confusing.
GRUB2 users :
to edit the Grub file as root(so you can save your changes) run this
With Grub2, the bootloader in new installations of 9.10, the procedure is a little different. You should edit the file /etc/grub.d/40_custom and add the lines
Note that Grub 2 counts drives from 0, but partitions from 1, so /dev/sda1 becomes (hd0,1).
STEP4 - Having done that run
to rebuild the grub configuration.
Reboot and hold "shift" to see grub(incase its hidden) and select the installer.

mkdir /tmp/install_cd
mkdir /tmp/installer
sudo mount disk-image.iso -o loop /tmp/install_cd
sudo mount /dev/sda1 /tmp/installer
sudo rsync -a /tmp/install_cd/ /tmp/installer
sudo umount /tmp/install_cd
sudo umount /tmp/installer

STEP3 - Edit your grub configuration file
GRUB1 users :
to edit the Grub file as root(so you can save your changes) run this
gksudo gedit /etc/grub.conf
or
gksudo gedit /boot/grub/menu.lst
Edit your grub configuration file to boot from the new partition by adding the lines
title installer
root (hd0,0)
kernel /casper/vmlinuz boot=casper root=/dev/ram ramdisk_size=1048576 rw
initrd /casper/initrd.gz
the first line after the title tells grub which partition contains the installer. hd0 stands for "first hard disk," and the 0 following it standards for first partition. You will need to change this if your installer partition is different from /dev/sda1. sdaN becomes (hd0, N-1), sdbN becomes (hd1,N-1) and so on. As you can see, grub starts counting from 0, which can be confusing.
GRUB2 users :
to edit the Grub file as root(so you can save your changes) run this
gksudo gedit /etc/grub.d/40_custom
With Grub2, the bootloader in new installations of 9.10, the procedure is a little different. You should edit the file /etc/grub.d/40_custom and add the lines
menuentry "installer" {
insmod ext2
set root=(hd0,1)
linux /casper/vmlinuz boot=casper root=/dev/ram1 ramdisk_size=1048576 rw
initrd /casper/initrd.lz
}
Note that Grub 2 counts drives from 0, but partitions from 1, so /dev/sda1 becomes (hd0,1).
STEP4 - Having done that run
update-grub
to rebuild the grub configuration.
Reboot and hold "shift" to see grub(incase its hidden) and select the installer.
