Deleted all partitions of my hard-drive from an unistalled ubuntu and now my windows wont start

[Santicruzado]

I was trying to uninstall Ubuntu from my computer, and for that I went to the windows disc manager, but it didnt gave me the option to delete the ubuntu partitions of my disk, so i decided to uninstall it from an uninstalled version of ubuntu, I opened Gparted and deleted all extra Partitions that I thought i wouldt need, but now when I Boot my computer it says that i dont have any operative system installed. Can anyone help me how to do those partitios again? and not to pay for an operative system that i already have in my computer but without the necesary partitions??

Thanks a lot for answers

OK. Firstly, what you should have done is this: http://www.tomshardware.com/forum/id-2020004/post-remove-linux-replace-windows.html

Did you leave any partitions there?

What version of windows is it? Do you have a product key (e.g. on the bottom of your laptop)?

You may have just removed the MBR which is required to boot windows. However if you removed your windows partition, theres no way for windows to boot, because you effectively deleted it all.

Assuming it was just the MBR you wiped out, you should be able to rebuild it using the windows install disc.

This guide should be sufficient:

I just left the C disk and the recovery one. It is Windows 8.1 an I dont have the product key :/

What do yu recommend me to do? just take it somewhere for them to reset everything? or keep trying to do different things?

Linux is a good free option, although this is what you're trying to remove. If you bought your laptop/computer from a retailer, you may be able to contact them for a OS license, these are typically included with your purchase.
