How do I uninstall Ubuntu 9.10

Depends how you mean uninstall?

First backup your "/home" folder by copying it to external hard-drive or dvd's.

Then use an 8.10 Cd (or 8.04) Cd to 'reinstall' bu when you get to the partitioning section try "Manual Partitioning". Make sure that all the Partitions are UNticked in the "Format Partition?" column. Also edit the ubuntu partition to make it's "Mount Point / ", the / mark shows where to install Ubuntu. There will be a warning message but you can check for yourself in the summary that no partitions are getting formatted and also you have just backed up all your data & settings :)

take care. Good luck and regards from

I'd fix firefox and the ntfs mounting instead of reinstalling.

If you are trying to run your windows apps in Linux it ost likely will NOT work as you will be missing registry keys / system32 files in your wine virtual drive. They will only run if they are VERY portable.

Wassup with firefox?

have you tried this:

killall firefox; mv ~/.mozilla ~/.mozilla_old; sudo apt-get --purge remove firefox; sudo apt-get --purge autoremove; sudo apt-get clean; sudo apt-get install firefox; sudo apt-get clean; firefox &

That will rename you profile so you get a fresh one, then completely remove, redownload and completely reinstall firefox.

Hmmm, now i have re-read your question i am wondering if you installed Ubuntu inside Windows using the Wubi? A full proper install like this

https://help.ubuntu.com/community/BootFromCD

https://help.ubuntu.com/community/WindowsDualBoot

tends to work much better because it doesn't rely on Windows systems in order for it to work. This also results in more Ubuntu options on the bootup menu, such as "Recovery mode". At the moment do you get just 1 option for Ubuntu or 2 or more options?

Thanks, good luck and regards from

I have a Lenovo T61, 2GB RAM, Nvidia quadro 140M, centrino T7700, 160GB HD. I am running win XP and ubuntu with selection at booting time. I had ubuntu 9.04 and it was FAST!! I was so proud of it... running circles at windows, and it became my O/S of choice. Then, a few days ago, I decided to "upgrade" to 9.10. BIG MISTAKE! my system is SOOOOO SLOW.... IT IS LIKE WINDOWS!

How can I remove completely 9.10 and reinstall 9.04?

thanks

You must reinstall Jaunty from fresh, you cannot downgrade

thank you! I was thinking of doing that, after reading some of the other questions and answers... Ubuntu has to focus in performance, not on whistles and bells like windows. My daughter chose to go with windows 7 instead of Ubuntu 9.10. Oh well, it is a never ending quest to be better than the competition.
take care,
ghost

hi,

I'm wondering if anyone here knows how to safely and fully uninstall ubuntu 9.10 and ubuntu related stuff (anything related to ubuntu that may prevent another os form installing properly)

here's the thing: I only have ubuntu as the only running os on my system. I need to restore my system back to ntfs and fat32 drives as they were when I got the laptop and will thereafter install windows xp pro.

thanks

Thank you

I know this isn't the right place to answer, but its necessary to get
this information across so I apologize.

To uninstall an OS you will have to install another OS like may be
Windows, just put in the CD and then you will have to format your drive
and install a new OS on it.

PLEASE PLEASE BACKUP YOUR FILES BEFORE DOING ANYTHING :)

Hi Guys: thanks for the answers, but you misread the question. I already have XP and two installed ubuntu 9.04 O/S's. I need to erase one of them. What I will do is go to XP-start-control panel-admin tools-computer management-disk management. then I will select the partitions I want to delete (the 2 ubuntu partitions)
Then I will reboot the computer and I will get an error grub loader. then I have two choices: 1. use the XP original CD and use the command fixmbr to erase the grub loader or 2. Reinstall Ubuntu 9.04 again with the desired partition size. Both ways are time consuming, but they work fine.
I have a Lenovo T61 with 2GB RAM, Centrino T7700 (2.5 MHz) 160 HD, 512 MB Nvidia quadro card, 15.4 wide screen, etc...
Linux is the best O/S in the market, but unfortunately, people DO NOT want to change and they rather complaint about the slow windows and blue screens of death.
Long live the Open Source movement!

Hi :)

Please ask a new separate question
https://answers.launchpad.net/ubuntu/+addquestion

Or ask at
http://www.linuxquestions.org

Each of you have a different problem that can be solved but in a different way for each. While it might look like a similar problem there are a number of different causes. An apple is a fruit and so is an orange but they are quite different from each other. Please ask your questions separately so they can each be handled in an appropriate way relevant to each separately.

The original question appears to have been re-written so this thread is now useless to anyone searching through the "previously answered questions database" and many of the answers seem quite absurd now.

If you can get to a command-line and type in

sudo fdisk -l

where "-l" is a lower-case " -L" and include the output from that into your new question then that might help people solve your various questions. As an example of what i mean by "the output" here is the output from my machine

user@Ubuntu904:~$ sudo fdisk -l
[sudo] password for user:

Disk /dev/sda: 20.4 GB, 20496236544 bytes
255 heads, 63 sectors/track, 2491 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xc009c009

   Device Boot Start End Blocks Id System
/dev/sda1 * 1 856 6875788+ 7 HPFS/NTFS
/dev/sda3 1152 2491 10763550 83 Linux
/dev/sda4 857 1151 2369587+ 5 Extended
/dev/sda5 1119 1151 265072+ 83 Linux
/dev/sda6 857 1118 2104452 82 Linux swap / Solaris

Partition table entries are not in disk order

So you can see that several of us have a Windows (sda1 on mine) and a couple of versions of linux installed on our machines (sda3 & sda5 on mine, they both share sda6). You can probably work out that my partitions are not laid out in disk order, on my disk it starts with sda1 but the next partition is sda4 which is an "extended partition" which contains first sda6 and then sda5. Finally the last partition on my drive is sda3. It is quite normal for a disk to have reached this level of apparent confusion without there being any problems.

Here is a link helping you to get to a command-line
https://help.ubuntu.com/community/UsingTheTerminal#Starting%20a%20Terminal

Perhaps it would be wise to try doing this from a "Live Cd session" which you can use by booting up (switching on your machine with the Ubuntu cd in the cd/dvd-drive)
https://help.ubuntu.com/community/LiveCD

Good luck and regards to all of you from

Hi again

From the way the question has been re-written i think we would need you to run a Live Cd session using this link for guidance
https://help.ubuntu.com/community/LiveCD

When you get to the normal Ubuntu desktop in the Live Cd session please access a "terminal console" so that you can type (or copy&paste) onto a command-line. This guide should help you get to a command line
https://help.ubuntu.com/community/UsingTheTerminal#Starting%20a%20Terminal

Try using the mouse to copy & paste this command

sudo fdisk -l

it will normally ask for your password but this is your normal user password not your SuperUser one and as you type it will not show stars or anything but it will recognise your normal password after you press enter. On a Live Cd session it wont bother to ask for a password at all if i remember rightly.

Please give us the output from that!
Good luck and regards from
Tom :)
