Progress! But problems remain.
Posted: Sun Feb 17, 2008 4:10 pm
About a fortnight ago I received helpful suggestions from Fred and timw06 and I have now just had time to follow them - I have downloaded the article 'Boot with Grub' from http://www.linuxjournal.com/article/4622, and produced a grub floppy, and even more usefully, have downloaded the iso file to produce a Supergrub CD - together with documents for both. (Googled for URLs). I've not yet had time to investigate Puppy Linux but I have produced a CD to install it from.
Now I can easily boot into different LinuxMint versions and compare what they will do.
Difficulties which I have reported before remain: why?
In Celena, I get almost completely consistent booting with partitions correctly mounted, except (hd2,0) is not initially mounted, and after that I can't access it. I try to change it and it reports "read-only file system". [See terminal log below]. Celena is installed in (hd0,4).
In Daryna, I nearly always get one partition (not always the same one) mounted to 3 different /media, leaving 2 inaccessible. This I routinely correct from the terminal. But (hd2,0) is initially mounted, so I can access it and happily write backup folders to it - and access the ones previously placed there. Daryna is installed in (hd2,7).
Why is the behaviour of the same partition (hd2,1) so different in the 2 systems? It is formatted ntfs, and the backups come from my old Windows system where I keep all my current work (including Linux files) as well as archives, except e-mails. I don't use my /home/theo/documents folder.
Here are the terminal logs in both systems for gurus to elucidate (if you can kindly spare time!)
17/2/08: terminal in Daryna, booted via Supergrub. Note that sdc1 is accessible to user. (This is after initial ~$ df -h revealed 2 incorrect mounts of /dev/sda1)
