I'll try to keep this short:
Win XP Pro installed in hda1.
Bianca was installed in hda2 - erased.
Cassandra is installed in hdb5 - boot always shows errors but succeeds.
New partitions created in hda2: / = 2GB and Linuxswap = 2GB; ~ 33 GB free space - manually selected for installation of Celena from cd burned from iso file, md5sum checked.
Celena Standard installed - everything appeared to proceed without snags. At an early stage the script says "see release notes" and that took me to a blog - I contributed at item No: 40. I didn't import anything from other places, expecting to do that later. (Too complicated to find them all! - there are Tomboy notes, Bookmarks in Firefox, Addresses and mails in Thunderbird, to say nothing of Documents, which still sit in my Windows filesystem).
At end of installation, cd still present, no offer to eject it - wouldn't eject by hand - so brought up Celena menu, Quit, Shut down - and ejected during that.
Re-boot - Grub offers same as before - no trace of Celena!
Can't find it in system anywhere - desktop screen shows sda1, with properties identifying it as Desktop configuration file (It is my Win XP). But "Computer" icon on desktop opens to show no sign of hda1, but does show a 2 GB partition in that drive (identified by drive type); properties showed this as unmounted so I have entered settings as / and ext3 with mount point sda1.
Will now re-boot to see if that retrieves the installation - I doubt it! During the installation I think mounting at sda1 was automatically selected.
Yours hopefully -
