Dear all in Penguin World,

Let me first of all introduce myself.

I'm not a total newbie, but I don't like spending countless hours solving computer problems. I mean, I know my way around Linux, as I've been using it on and off during the years, and I've installed it on a few computers for friends who didn't know what to do to speed up their old machines.

Most of all, I appreciate the fact, that you can install just what you want, and not get your computer clogged with useless software.

I need a speedy machine, just for seamless email handling, browsing, and a bit of office.

Now, let's get straight to the problem.

I use Lubuntu on an Intel i3, with 4 gigs of RAM. It runs nice and smoothly.

I don't know what made me do it, but today I decided to mess around with system settings, in order to fine-tune my laptop's brightness. Long story short, I screwed everything up and had to reinstall the system. I didn't do a clean reinstall, and once I got into my newly reinstalled system, I noticed the PC wouldn't connect to the Internet. So, I decided to erase the partition and reinstall from scratch. It's working fine, now, but when I was told to reboot the computer to use my newly installed system, I first removed the USB pendrive from which I was installing Lubuntu, and then clicked on "Reboot". At this point, I got some strange error messages from the command line interface and I just pushed the power-off button and booted the PC again. Everything's fine, but I'm wondering if this could have messed things again, lending me to face new problems in a few days, when I won't either have the time nor the will to go through this all again.

I know this is a strange question, but trust me, I've had enough with reinstalling and resetting everything up.

Many Thanks,
Leonardo

I can't imagine you would get any useful help unless we knew what the 'strange error messages' were.

Probably no problem. Most likely all you did was prevent an orderly shutdown which most often is not a problem. The fact that the computer rebooted without a problem indicates you got away with it. Forcefully shutting down can cause problems because all open files are not flushed and closed, etc., etc. This CAN be a problem, large or small, but often is not. You may have a file somewhere that lost some data, of course, and Murphy assures us you will find that out at the worst possible time, or you may not. Since it rebooted and you have not found anything weird yet I wouldn't worry.

Don't fix things that not broken yet
Just let your PC to work.

Normally, you should only remove the installation media after a clean shutdown, when it tells you it is about to reboot. As above, likely just didn't shutdown cleanly. Most distros check the file system at start up, so looks like you're OK.

Hi,

Thanks for your reply. I can't remember what the error messages were. They were mostly about impossibility to retrieve necessary files and execute commands, this happened after unplugging my installation USB device. Thus, I had to shut down the computer by pressing the Power button.

Thanks all for your replies. The system seems to be working fine.
