My Ubuntu partition lost the login screen. The graphics are off and is unreadable. Will a reinstall just overwrite the OS or clobber my data too? I the LiveCD. Ubuntu 16.0.4

By default, it will delete everything. You have to select the "something else" option and make sure the Ubuntu partitions are not to be formatted. – mikewhatever Mar 19 '17 at 18:22

I do reinstalls sometimes and only "something else" allows you to choose not to format a partition. I do this to keep my HOME folder – userDepth Mar 19 '17 at 23:50

I do as u say, get a partition table. highlight the Ubuntu partition. Click on "Install Now". Get a message: "No root file system defined. Please correct this from the partitioning menu." If I double click on the Ubuntu partition in the partition table, I get a popup that gives a (partition) size, a field "Use As", a checkbox for format, and a mount point. i assume the mount point is "/" & the "Use As" is the same. in the partition table it is "ext4 journal file". i get a warning about files being erased & another partition "sda6" being used as a swap file. "sda6" already exist. – givonz Apr 02 '17 at 18:09

well, it did work. i got a message that some things couldn' t be reinstalled after installation. haven't figured out what that is yet. but, all my data seems intact. thanks. – givonz Apr 02 '17 at 19:00

If the graphics are unreadable, try Control+Alt+F1 and then Control+Alt+F7. That would switch to the text terminal and then back. That fixed my issue here.
