Hello,I am the person that will be helping you today.
When you chose to install Ubuntu, did you choose to erase the whole disk?
I will be standing by, looking forward to your response.
In that case, you will have to reinstall Windows from disc. On the Acer, there is a Microsoft label. On that label, which version of Windows is listed?
No, what? You don't have that sticker on the computer anymore?
That means that you removed them. Did you make a note of the Windows product key before you removed it?
Yes, there is a way to reformat it. You would need to get your hands on a Windows CD before you can do that.
Do you recall which version of Windows was on the computer?
That is correct. Do you have a working computer with a CD burner or a blank usb flash drive? If so, you can purchase and download Windows 7 and a Product key from the following page: http://product.key-downloader.com/windows-7/windows-7-pro?gs=5&gclid=CjwKEAiAkajDBRCRq8Czmdj-yFgSJADikZggrpHXdnbUp08UUsA4TWc_eZ61EgxNOxEJnEImsPYb8BoC3lDw_wcB
Is there anything else that I can help with?
I don't understand what you are saying. It will work. All you have to do is install it.
Well, I didn't know that it was giving you errors while installing because you didn't tell me. What errors are you having?
That's okay. Is there anything else that I can help you with today?
In the future, if you need any help I can, please let me know.
