My Ubuntu installation crashed during updating and will now not boot fully. I have tried reinstalling as from a previous answer on here suggested but the option to wipe my original Ubuntu installation is not there.
I don't want to wipe my windows install, just reinstall the Ubuntu partition. I assume this can this be done from the something else option - but there are lots of options when I go to 'edit partition' which I'm not sure about. I'd think it should be an 'ext4 journaling file system' and format the partition but thought I would check before messing with settings I don't understand. Thanks for any help!
