Hi, when grub comes up with a menu, select the newest version
and check it provides the hardware and configuration you require (or are used to).
With newly installed kernels I use the verbose boot option to view the
text as the (Linux) system starts watching for error and fail massages.
The old version is there in case you can't boot properly with the new install.
You can remove any old entries through the manager (Configure My Computer) boot options.
Usually (Mandriva free) the entry "Linux" is the newest version,
but the newest version is also listed, as you show above here.
This gives clarity to choice when you need it, but otherwise is a bit daunting.
Personally I have not installed ONE since the first ONE, I can't remember
which version, but have been under the impression that it contained the
most adaptive system to be compatible with a large variety of machines.
(but not necessarily very efficient installed on a hard-drive)
You may be able to find backups of system files (filename~) in /etc and/etc/(package.name)
Also check for hidden files in /home/(user) and /home/(package.name).
You may be able to reinstate some of the functionality you had before.
One thing you discovered is my pet hate.
When updates come in, they are "repository updates" Not necessarily for my system.
Always check, unless you have installed the whole DVD, you won't be using them all.
Like samba (for example), if you don't have to connect to m$ machines you won't use it.
Otherwise, I recommend installing 2009.0 free release, it has an improved kernel and is a bit easier to get external devices working.
And keep telling your friends, family and colleagues about FOSS, about the lack of hardware support from manufacturers, to put pressure on those manufacturers that are ignorant and too greedy, riding on the back of Buggy Proprietary Operating Systems.
Any other questions, ask here?
Regards, Glenn
