>My primary concern is: What happens to my data/os when it is started up
with a new motherboard/processor/onboard-graphics?
Yes, I knew why you were asking and I was hoping someone would pop up with
the definitive answer. But while we're waiting, I can give you a few things
to watch out for.
I build and repair systems, so I work with a wide variety of brands and
architectures. I can tell you that in my experience, when swapping
motherboards things never happens in the same way. Sometimes it goes well,
and sometimes not.
Here's a couple of things that I would do:
First, backup your data. If it's a critical system, I would clone the disk
and work with the clone.
Secondly, if you have a proprietary video card driver, it might be best to
revert back to the more generic Ubuntu drivers. It's possible this step
might not be necessary, but at least know what drivers you've installed that
are not included with Ubuntu. It might give you clues if something goes
Third, depending on how you connect your hard drive(s) and optical drive(s),
and depending on the new chipset, the drives device designations will likely
change. For example, if the boot disk is /dev/sda in the old system, it can
easily become /dev/sdb in the new system. This could mess with any
customizations you've done, like Samba shares, etc.
For this reason, you should open your /etc/fstab file, and make sure that
all drives being mounted are using their UUID numbers to mount, rather than
'/dev/sda1' etc. It's easy to change them over, and it would be a good idea
to test any changes while still using the old system. How to do this is
mentioned at the top of the fstab file. By the way, no need to mess with the
entry named 'proc'.
Well, that should get you started, and hopefully others will tell you things
to watch out for as well. Good luck....
