Not so much uninstalling provided software as uninstalling any previously installed
I spent a week playing around with multiple “clones” on my installation
removing various software packages to find out if there was a way to remove
a previously installed copy of Roxio-pro 10 and replace it with a newer version.
The beauty of playing with “clones” is that if they are rendered useless for
any reason, it is like practicing pouring spoiled milk outside, nobody cares
if it spills or not… you weren’t going to drink it anyway.
if the old version was uninstalled first the computer “lost” the optical drive
so that the newer version (on a DVD-ROM) could not be installed… because after removing the burning software the optical drive is no longer “seen” within the OS (not even via a USB connected optical drive…)
So my “official” recommendation is that if you are installing newer
burning software leave behind the “old”, just delete the icon to access it.
In my case I eventually DID eliminate the “old” and what pressured
me to doing it was curiosity… I wanted to know IF it could be done
and HOW to do so… and it was such a complete PITA that even
though I know how to do it I don’t want to do it again.
(frankly it’s easier and less time consuming to start over from scratch with a new HDD and a Windows installation disc)
There is a lot of stuff I do purely as "proof of concept/ability/capability"
rather than doing those things because I “need” to do them.
The only “need” I had was for the knowledge of how to do it should the
actual “need” manage to present itself.
Knowing how (at my leisure) is far better than rushing through a steep learning curve at some later time (when far less convenient) when I actually do need to know… not to mention that knowing exactly what you are doing makes it possible
for you to make your doing so look “like magic” to those of the “uninitiated”.
maintaining a reputation as a miracle worker is actually more difficult most days than actually being a miracle worker.
The “clue” that you have experienced a damaged registry and that the OS no longer “Seen” the OS is indeed an OS problem is simple…
Boot the computer from a Windows installation disc but stop short of formatting the drive or installing windows… if the optical drive is "seen"
in bios and actually starts to load files to open the installer it generally isn’t a “hardware” problem with the optical drive.
For an actual hardware problem:
Another easy check is shut down the computer and install another “known good” optical drive and when you re-boot
if that drive is “seen” by the OS you know it WAS a hardware
problem, at which point you can drop the “old” optical drive in the recycling bin.
I like these two testing methods because the results are utterly unambiguous.
You get a definite answer.
