A couple of years ago I received a desktop computer through a local program that had Edubuntu installed (I am afraid I do not know the release number). Recently the software updater advised that an updated release was available and I attempted to install it however during the update my computer froze and a family member shut it down. When I restarted it, it failed to boot, citing a "failed to start load kernel modules" error. I have tried several remedies suggested on this site to fix the problem, in particular what has been suggested on this thread https://askubuntu.com/questions/779251/what-to-do-after-failed-to-start-load-kernel-modules. These suggestions did not resolve the issue for me.
I did not have many programs installed that I care to recover, I did however have various .odt, .doc and .pdf files I would like to recover, and if possible I would also like to reinstall Ubuntu so I can continue to use the machine.
I have managed to boot using a USB stick with Ubuntu 18.04.04 LTS. Now that I have booted, how can I go about accessing my files?
I see here https://help.ubuntu.com/community/UbuntuReinstallation that I should have the option to "Upgrade to Ubuntu 18.04.04 LTS" while installing but that option is not listed for me.
Instead I have the option to "Install Ubuntu 18.04.04 LTS alongside Ubuntu 16.04.6 LTS". If I choose this option will I still be able to access my old files while operating in Ubuntu 18.04.04 LTS?
