As @David said in the comment above, running an installation across the network is challenging, but can be done.
I use MAAS for that purpose at work - on a segregated network where it can control access to everything (DNS, tftp, web proxy, and PXE booting, and other details about the network it controls).
It's pretty straightforward to set it up - https://maas.io provides you all teh instructions if that's your direction. It's not really for home use however, as most home networks don't have the capability to have a segregated network.
Without some sort of tool to provide PXE booting on your network segment and then provide file services to install from, it's pretty challenging to make it work. It would be a lot easier to download the installation media onto a USB Key with enough space to hold it and boot your computer from that. You may even be able to enter rescue mode and repair your broken installation. There are details for most of that on the ubuntu website.
