Upgrade to Slaine
I'm having problems to boot my recent Taranis system. When I had installed it, Trisquel configured it in such a way that it created a new general partition as sda4 on my system and in that there are sda5 which holds my Trisquel installation, sda6 - a swap file system and sda7 as a general data space larger than the latter two.
Now I'm wondering if I create a Trisquel Slaine live USB to install the new system if it'd be capable of detecting the old Trisquel system and overwrite it. If that would be possible, I think I'd get the new version and solve my boot problem at the same time :/
Thanks for all replies in advance!
For educational purpose, you had better try fixing your installation instead of doing a reinstall. Anyway, during the installation process you can choose a custom partitioning that allows you to specify where the root (/) partition should be. You can select the one used by the previous install (/dev/sda5 if I understand well what you wrote). It would, of course, be formatted. /dev/sda7 would not be touched. As a consequence, you do not need to backup this partition.
