Upgrade to Ubuntu 13.10 from ISO image [duplicate]
- Download the alternate installation CD
- Burn the ISO to a CD and insert it into the CD drive of the computer to be upgraded. If the ISO file is on the computer to be upgraded, you could avoid wasting a CD by mounting the ISO as a drive with a command like:
sudo mkdir -p /media/cdrom sudo mount -o loop ~/Desktop/ubuntu-11.04-alternate-i386.iso /media/cdrom(make sure you use the actual filename of the iso you downloaded ^^^^ )
- A dialog will be displayed offering you the opportunity to upgrade using that CD.
- Follow the on-screen instructions.
If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:
gksu "sh /media/cdrom/cdromupgrade"
Or if you're using Kubuntu run the following command using Alt+F2:
kdesudo "sh /media/cdrom/cdromupgrade"
Just make a bootable USB or CD/DVD and boot it up as you would install ubuntu. When you are asked what you want to do just select "Upgrade...":
Okay, so since cdromupgrade file is missing or not available, the next best thing is to create a LiveUSB and go on from there. Since you're upgrading from 13.04 the entire process should be rather flawless.
- Open the Dash and open the *Create Startup Disk * option. This opens a window, from where you can choose the iso file and destination.
- Now select the 13.10 iso file and a usb (remember to use the erase disk option before you mount the image) and create your startup disk.
- Now, upon re-booting you should boot directly into the USB. Select the install Ubuntu 13.10 option.
- The installer window would present a number of options to you depending on the other OSes present in your hard drive.
- Choose the
Upgrade to 13.10 option. This should get you going and ready for 13.10.
Hope this helps you.
You can boot ISO files from Grub. However, I think you will need to have the ISO file on another medium (such as another hard drive, or a USB/CD/DVD)

Though if you have your /home in a separate partition (or any other non-standard filesystem configurations like that), this will not work.... You must reinstall, rather than upgrade.
Though you can simple upgrade incrementally through the normal method:
