Usb Boot took over computer

Here some general info on howto made a bootable usb stick with Ubuntu netbook remix on it...

- 1) Download ubuntu-10.04-netbook-i386.iso from http://releases.ubuntu.com/10.04.1/

http://releases.ubuntu.com/10.04.1/ubuntu-10.04-netbook-i386.iso

NOTE: to get best download errors check please prefer the torrent protocol to download the iso image

http://releases.ubuntu.com/10.04.1/ubuntu-10.04-netbook-i386.iso.torrent

If you are using Windows, install Deluge torrent client: http://deluge-torrent.org/
if you are using Ubuntu you have already trasmission installed to manage the .torrents files (you can also install Deluge on Ubuntu).

The torrent protocol have good download errors checking, downloading using the http or ftp protocol may result with a file with errors in it.

- 2) (VERY IMPORTANT POINT) check the md5sum of downloaded iso image

https://help.ubuntu.com/community/HowToMD5SUM

if the md5 of downloaded iso image doesn't match with the md5sum on this page:

http://releases.ubuntu.com/lucid/MD5SUMS

redownload the iso image again (please use the torrent protocol) or you are going to waste your time by try to install Ubuntu from a bad iso image.

( we must ALWAYS check the md5sum of downloed iso images before to burn it to a cd or to tranfert on a usb stick ) .

- 3) install and use unetbootin http://unetbootin.sourceforge.net/ to put on the usb stick the md5 verified iso image.
     unetbootin can be installed and used on Ubuntu and on Windows...

- 4) boot your pc from the usbstick (you may need configure your bios) and install Ubuntu

I forgot to mention that I installed the desktop version on the usb before I noticed there was a netbook version so that is the first one I tried to boot on the laptop and could not get that one to boot at all.

I downloaded and installed the iso onto the usb drive and it boots up fine. Now how do I get rid of the boot that is in my memory so I can get back to windows.

Please be clear, what have you done ?
1) you have installed Ubuntu...
2) you have put Ubuntu on the usb drive and you want to install
3) you want only try Ubuntu on the usb key and you want not install it
4) you want to start Windows and leave Ubuntu on usb key to future installation

I only want it to run off of my usb drive it now does. Now the laptop still tries to run ubuntu when I start it without the usb in.
I want to get rid of the boot that is starting when the usb drive is not plugged in so windows will start.

As marcobra said before, please be clear.

When you say the "laptop still tires to run ubuntu when I start it without the usb in", do you mean

1) the laptop is accessing the usb looking for something but does not find it? or
2) you get a menu that gives you the choice of starting Ubuntu or Windoze? or
3) ????

If it is 1), you will need to change your boot order via the boot menu by pressing either F12 or ESC while the computer is starting up.

If it is 2), you installed Ubuntu on your laptop without realizing it. If it gives you the choice, you still have Windoze on your laptop. You can restore Windoze by booting up with your Windoze installation disk and performing a system recovery.

If it is 3), please be more clear.

If it is 4), you may have installed over Windoze and you'll need to re-install it from your Windoze disk.

The laptop still tries to boot ubuntu without the usb plugged in from the start it doesn't give me any boot choice. It gives me a choice of starting from the drive or installing. When I pick to boot from the drive it says cannot mount and goes to a prompt. I tried changing the boot order to the hard drive first but it didn't change anything. While in ubuntu booted from the usb drive I can still see all my files and windows in the C drive and no ubuntu installed on the drive so windows is still there. I guess I will try restoring the boot sectors with my windows 7 dvd.

Okay I tried to fix it with the windows 7 dvd but it didn't help. The only thing I can think of is that ubuntu installed it's self onto the ram. I searched every where on the hard drive to see if it was on there but I don't see any boot files or folders. I will try the ultimate boot disc and see if maybe one of the ram tools on there can clear it out.

It is fixed I used the ultimate boot disc opened g partition and it showed another partition that I could not see using ubuntu on the usb drive so I deleted the partition and used the windows 7 dvd to fix the start up files and I'm back to windows 7.
