I have Debian/Windows dual-boot laptop, and I want to re-install Debian on it, leaving the Windows partition untouched.
Basically, I want to leave the specification for all the partitions the same. I just want the new Debian installation to completely overwrite the old one.
When I get to this dialog in the installation sequence, I am not sure how to proceed to achieve the goal above:
The settings above are already the way I want them, but if I select
Finish partitioning and write changes to disk
and click Continue, the installer complains with
No root file system
No root file system is defined.
Please correct this from the partitioning menu.
If I select #5 or #6, the installer requires me to re-specify all the configurations for each partition, without telling me what their current settings are. Since I don't know how these partitions are currently configured, I cannot replicate these configurations from memory.
What steps should I follow to retain the partition specs as they are, and just overwrite the current Debian partition(s) (#5 and #6 in the listing above) with the new Debian installation?
