How to Remove Ubuntu?!

[mbarvian]

Hi guys, I just installed Ubuntu on my Toshiba satellite laptop, but the wi-fi wasn't working on it, so I want to remove it, but can't see how. I am running the latest version: 8.04, but do not have the Windows Vista disc that should have came with my computer. Is there any way to fully remove it?

the way you remove ubuntu is by installing over it. There is no other way around it. Since you dont have the windows disk that is a bit more difficult. Post the output of

sudo fdisk -l

Maybe the manufacture left a recovery partition on your harddrive.

Put the live CD in and then use GParted on the live CD to simply erase the Ubuntu partition and then re merge it to Vista if you want.

You will have to fix the mbr or you can also use SuperGrub to fix your grub entries again.

well if you were to just delete the ubuntu partition, GRUB would stop working and you wouldnt be able to boot into vista.

i have heard of people restoring the default vista bootloader without the original vista cd but i cant remember how (it is definatly possible though)


EDIT: oops, i should have refreshed the page before responding

woah, woah. completely removing ubuntu is not the best way to go about things. why not let us help you fix wifi? my guess is you just have to do some config with your wifi system to get it to work, and besides, if you don't have the vista disk on hand, then you'll have to download the iso and burn it to a disk anyway, which will require internet access on ubuntu (unless you have another computer set up, which I assume you do since you're posting on this forum).

if you can, run these commands in the terminal (applications > accessories > terminal, if you don't know), and post the output, and we can start helping you fix your wifi.

lshw -C network

ifconfig

dmesg | tail -n 50

EDIT: this is all assuming that you would want to fix your wifi instead of erase your system.

Yes. You can remove it.

Do you still have Vista on the HD (i.e. dual-boot)?

If yes - install EasyBCD (http://neosmart.net/dl.php?id=1)

This will restore the Vista bootloader.

Then you can just boot from the Ubuntu LiveCD and use Partition Editor (GParted) to delete the Ubuntu partition.

If no - then you can still remove Ubuntu, but Vista won't be there either.

PS: This assumes you did a full install, and did not use Wubi to install within Windows.

PPS: Did you want to try to get wifi working in Ubuntu?

OK, I guess I shouldn't jump to conclusions trying to remove it instantly (although it would be nice). This is the wi-fi problem: when I click on the two computers at the top right, it opens up a Connections manager thing (again, very new to Ubuntu). However, everything is listed as it should be there is no Wireless tab. How do I fix this?

[SunnyRabbiera]

well firstly dont expect to learn a brand new OS right away, secondly have patience.
I am sure we may have a solution to your wireless issue if you give us time

[john91]

It's really hard to diagnose the problem without knowing some info about your hardware. if you could post the output of the commands I placed in my last post, it'll help us help you.

We need a bit more info...

Is it a USB or internal wifi card?

In Terminal (see link below if you don't know how), copy / paste the commands john91 suggested, and post results back here.
