jumperin on "Installation wordpress on quickinstall is only installing .com and not .org"

Good Afternoon,

I have a question,
I bought a web hosting in hostgastor but already had the domain in wordpress.com, then went to QuickInstall to install wordpress.org, and quickinstall have sent me an email with the data and I walked into account and still after all with wordpress.com and had not installed the wordpress.org, now I can not even log in with the data that quickinstall have sent me and only with wordpress.com account data, how can i use wordpress.org?

You will need to ask your hosts to supply you with a temporary domain so that you can install WordPress on your hosting. Once you have imported everything you ant from your old wordpress.com site, you will then need to transfer the domain over so that it points to the new WP install.

I would like you to explain to me, because I don't understand why I need a new domain, if I already have my own domain?
I don´t have anything in my website and I never posted anything there. I only created an account in wordpress.com and I created and bought my domain there, but I realized that I couldn't install plugin's. After that I bought a web hosting in hostgastor with my own domain(from wordpress.com). So I have done the quickinstall for install wordpress.org, but when I put the Admin Url, username and password that they gave me, the only thing that appear it is a workspace of wordpress.com.
So now how can I open the workspace of wordpress.org if the admin url will everytime open jn wordpress.com? I have tried to export from wordpress.com, but the only thing that I have there is a XML file.

Thank you.

Domains point to wherever you tell them to point by way of their name servers. Currently, your domain is pointed to WordPress.com.

You need to either change your domain's name server (consult your domain registrar's documentation for this) to your hosting provider's name servers (contact your hosting provider's support for these), or you need to ask your hosting provider for a temporary domain now while you work on your site and change the domain over late when you're done.

Also, to clear up any confusion, WordPress.com and WordPress.org are two different entities: https://codex.wordpress.org/WordPress_vs_WordPress.com

Your domain is still pointing at the wordpress.com site. You need to transfer the name servers to your new host (or update the DNS at WordPress.com to point to your new host).

See https://en.support.wordpress.com/change-name-servers/

For any questions related to the wp.com side of things, you need to contact WordPress.com support.
