I've been locked out of my Desktop computer for a while and could only get hold of an old installation CD with yakkety on it.

Can not upgrade
**An upgrade from 'yakkety' to 'bionic' is not supported with this
tool.**
I've tried upgrading a few different ways and get the same message that an upgrade from 16.10 to 18.04 is not possible with this tool. Running apt-get update, some of the repositories don't work also:
E: The repository 'http://security.ubuntu.com/ubuntu yakkety-security Release' does no longer have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
I read in a thread yesterday that you can manually edit the sources.list and upgrade to the next version (still an old one, but a step up), I found out that its called an EOL Upgrade: https://help.ubuntu.com/community/EOLUpgrades
I tried this but things didn't work out like I was hoping. Is this EOL Upgrade the only viable way to do this? Will I have to do 2 EOL upgrades (16.10 > 17.04 > 17.10)? I just checked and yesterday I tried to jump from 16.10 to 17.10:
sudo sed -i 's/yakkety/artful/g' /etc/apt/sources.list
Maybe that's why things went wrong. So to do it properly, do I need to run these commands:
sudo sed -i 's/yakkety/zesty/g' /etc/apt/sources.list
sudo sed -i 's/zesty/artful/g' /etc/apt/sources.list
sudo sed -i 's/yakkety/zesty/g' /etc/apt/sources.list
sudo do-release-upgrade
?
As for an alternative way, I have no files or anything on this partition I need to save so it doesn't matter if all user files on it get wiped out. I could make a partition just big enough to hold the Ubuntu 18.10 iso file, can I boot that partition like you would a CD?
EDIT: So I ran: sudo sed -i 's/yakkety/zesty/g' /etc/apt/sources.list
Everything went normal except at the end, I got the same message about repositories not having Release file:
W: The repository 'http://ie.archive.ubuntu.com/ubuntu zesty-updates Release' does not have a Release file.
Then when trying to upgrade, nothing happened:
