However, I don't have any OPTIONS after log on but a black screen with a line across the top with a 24hr clock??
That sounds like bare X. That would happen if you removed the mythbuntu desktop and ubuntu-desktop failed to install as a replacement.
Maybe switch to a console (Ctrl + Alt + F1), log in and run
aptitude search ubuntu-desktop | less
If it prints a list of packages (you can scroll using the enter key) that includes said package, it can be installed with:
sudo aptitude install ubuntu-desktop
When it is done:
sudo /etc/init.d/gdm stop && sudo /etc/init.d/gdm start (technically, just sudo /etc/init.d/gdm restart should work)
That should take you to the GDM log-in screen (if not, Ctrl + Alt + F7)
If it doesn't work but you want to back up your home folder, return to the console, log in and run sudo fdisk -l
That should print a list of your current partitions. The one that has XP should be the first one (it will be marked "NTFS"). If it has enough space to hold the back-up, just run
sudo cp -Rv /home/username /dev/sda1 (assuming the XP partition is sda1). Wait for it to finish and leave the console (alt + f7) again.
Can I simply install from scratch with my CD/ISO?? Upon shutdown/restart my CD starts up and runs OK...I'm """"unsure"""" what to do at that point? If I mount the HD that contains ubuntu, will it install over itself?? OR - will it corrupt my C: drive and install over windows??? I have to be SURE of this before I proceed!!
Yes, if the above failed to rescue your system, it may be the more convenient option. You'd better use the ubuntu install cd rather than the mythbuntu cd. Obviously, it's going to overwrite your files so you'd better make a back-up if there is anything worthwhile saving. It won't overwrite XP, though, providing you're careful. More specifically, at the partitioning stage ("Prepare disk space"), do NOT use "automatic" or "guided" but "manual" instead. Then:
- select the mythbuntu partition and click on the "delete partition" button. That should create "free space".
- select the free space, click on "New partition", now a dialog box pops up. Select "logical", 10240 as size, "Beginning", use as: ext4, mount point: /, "OK"
- select free space, "New partition", Select "logical", 2048 as size, "Beginning", use as: swap, "OK"
- select free space, "New partition", "Logical", all the remaining space as size, "Beginning", use as: ext4, mountpoint: /home, "OK".
Nothing has happened yet. If you get it wrong, start over by deleting the partitions you have created or selecting them and using the "edit" button. It is only when you click on the Forward button that your changes are actually written to disk (and you'll get a warning first).
While in the CD, I have NO ability to delete/cut/copy any of the myth pkgs....Just won't do it!! Can't copy my home folder, either!!! Response is ''easy tag'' won't allow...Permissions - I presume?
The livecd runs in its own environment, which is read-only. If you want it to run the programs on your drive, you need to select "rescue broken system" when the cd boots up.
To edit/copy/save your home folder from the livecd, you'll have to mount it first.
