I did a re-install for Daryna and that is generally - not always - booting OK - but the post you replied to referred to a new difficulty with Celena - from which I am trying to extract some recent e-mails from Thunderbird's Mail/Local folders file. Currently I can't open my Celena installation and need urcent help with that particular issue.
Difficulties with Thunderbird will be the subject of other posts - please don't start on that at present!
There is another topic in Newbies about Boot problems: Daryna in Recovery mode - where a related problem is discussed. The third post in that topic (my reply to the first reply) gives a fairly full account of my hardware and recent experience. All of this follows a re-install of Daryna trying to eliminate the puzzle of triple-mounting of one or other of the Windows partitions, resulting in loss of access to two of them. This continues, and has to be corrected at each boot by a sequence of sudo commands.
Perhaps it might come to a fresh download of the Daryna iso file, as you suggest!
BTW, I keep all my data and backups in Windows partitions, including directories such as .mozilla-Thunderbird and some of its sub-directories, and .tomboy, from different places and dates distinguished by the name of the folder in which they are placed.
Yours hopefully -
