Question newbie questions


Hi All, I am relatively new to Linux and have recently been trying a few different distros.

I have had some issues wich I have solved with reinstallation but got the first couple of questions:

1. what is the best way to uninstall a distro without affecting the other OSs in your computer?. I am multi-booting vista, Mint and Qimo and want to uninstall quimo. My fear is this will damage the other operating systems as it happened previously when I deleted the partition where i had installed mint mate. back then nor the other Linux distros neither vista would boot after this. The message I got was something like 'ngrub (or grub) missing" or 'can't find grub'

also:

error: no such partition
grub rescue>


note I had vista on a ntfs partition and all the Linux distros were on extended partitions.



2. my second question is why wouldn't ubuntu 12.4 lts or Mint 13 recognise my wifi. They are supposed to be new versions, if not the latest. But qimo 2.0 which is for my child seems to work fine and the internet works no problem. What i have done wrong for the professional distros not to work, but a child distro does? I think i followed the prompts exactly the same on the three.

Thanks for your help
Jonez.

After you delete the partitions, you must set the master boot record of the hard drive back to the windows boot loader.

The way I used to do this was running an xp install cd, go into recovery mode, type the command

fixmbr

And then reboot.

Somebody has made software to make this a little easier. I have not tried it, but it says it's free to use.

What wifi hardware are you using?

Please use the command

lspci -nnk

Thanks fakie_flip
I actually booted from the vista CD and run the repair utility. It finished "successfully" but when I restarted i got the same problem. Back then i did not worry about it and decided to wipe everything and reinstall. After all it is my child’s computer and there is nothing on it.

Please paste the full output of that command. If it's too big for this forum, then use a pastebin website and a link back here.

For future reference, when you have two unrelated questions, it's better to start a second thread, and use a more descriptive title.

So the relevant part of that output is this:

It tells what your wireless hardware is and what kernel module (the driver) is in use for it.

I searched this and found some other people reporting bugs with this hardware from a while back. I am not sure if it's been fixed.

Are you using the latest version of Ubuntu/Mint? Also plug it into ethernet, upgrade the system including the kernel, reboot and use the latest kernel. It might have bug fixes in it.

I am running ubuntu 12.4 lts and mint 13. pretty new. But also, as I said before, how come qimo 2.0 which seems older and simpler works fine with the wifi network without me doing a thing.

I see your running Ubuntu 12.4 and Mint 13. The latest releases are Ubuntu 12.10 and Mint 14. You can run them as a live cd to test your wifi is working before installing one.

Because somewhere in the code, there was a regression made. It could also be from a major change in the kernel that started at version 2.6.22.

Because you are using out of date distros that means out of date kernels being used as well. My best suggestion is trying the latest releases that will have newer kernel
versions and see if that resolves your issue.

ok,, do i understand correctly?
Because I don't have the latest versions of mint/ubuntu, which are both just one version behind, then my wifi doesn't work?
So, the versions they released 6 months before the latest were not capable of working with my wireless hardware?

It doesn't seem fair that if you are just 6 moths behind you can't use your wireless but if you are 2 years behind you may be able to.
I don't know how old qimo 2.o is, but the wireless works with it.


Cheers

Your wireless should work with a 6 months old release, but it will require that you keep all the updates fine tuned. The reason why software works out of the box in some distros is because each distro has different philosophy and some of them include software that other dont. Mint is a derivative of Ubuntu so chances are the behavior will be similar in your computer.

So first thing you need to do is connect your computer to a wired network and install each package update available for your system.

Here is the link to a post in the ubuntu forums http://ubuntuforums.org/showthread.php?t=1851312

Good luck to you!
