How can I restore Windows 7 after uninstalling Ubuntu?

I have an HP computer with 80 gb solid state drive with Windows 7 64 bit home edition installed. I had Ubuntu installed as well. It started to create start up issues. The boot order got changed and it defaulted to ubuntu.

I followed these instructions to uninstall Ubuntu
http://www.makeuseof.com/tag/how-to-…t-environment/

Now I am getting the error that GRUB is missing. I am not a computer programmer so I don’t speak this language. I did have a restore disc I created the day I brought the computer home. A friend helped me image the hard drive and create a restore disc.

When I went to use it today, it does not work. I click to boot from CD on start up and get this error:

“Windows has encountered a problem communicating with a device connected
to your computer.

This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing.

Make sure any removable storage is properly connected and then restart your computer.

File: \windows\system32\boot\winload.exe

Status: 0xc00000e9

Info: An unexpected i/o error has occurred”

I do not know what else to do. I want to restore my computer to Windows 7 only and maintain all operating system and programs on my 80gb solid state drive as always. I just don’t want to deal with Ubuntu anymore. Can anybody help me out further? Is my restore disc bad? If so what do I do?

    Hello, you could try installing the repair/installation disc in a USB flashdrive and start it from there.  If you want to get a repair image for windows 7 you could try in the following place:

    http://neosmart.net/blog/2009/windows-7-system-repair-discs/

    You can also follow the instructions in the next link about how to create a   USB repair disc.  In your case use method two described there:

    http://www.intowindows.com/how-to-repair-windows-7-from-usb-flash-drive-repair-without-installation-dvd-disc/

    or, the following:

    http://www.sevenforums.com/tutorials/92177-boot-windows-7-system-repair-disc-usb-using-grub4dos.html

    Of course, you will need to have access to another computer to follow the methods above.  When using a different computer, it is not necessary for them to be running windows 7.  Once your USB drive is ready, restart your computer and make sure to change boot order to USB.  There are some BIOS that do not allow to boot from USB but it is for older computers.  If for some reason your BIOS doesn't allow to boot from USB, just let us know, you still have options.  

    Once you restart computer and USB is being used, you could try the following:

    -- once you reach the language screen, click on next (unless your language is wrong, change the language.

    -- click on repair your computer option at bottom of screen
    -- select the windows installation to be repaired and click on next
    -- select command prompt option
    -- once command prompt opens, type the following commands and press enter after each one:

    bootrec.exe /fixmbr
    bootrec.exe /fixboot

    After each command, it should tell you if it was successful or not.  Once both commands are successful, restart your computer normally.  It should fix your master boot record and your windows 7 installation should start.  If you have a problem, leave a note on the comments.
