How to remove all search results for a previously-owned domain?

[ocon]

I am starting to use a previously owned domain which has several thousand results in the Google search results, none of which are valid.

I would like to completely remove the current listings for this domain.

I've created a robots.txt file to block all search engines, and I created an account with Google Webmaster Tools for this domain. I used their removal request tool [google.com...] and put in a request to remove the highest levels: www.domain.com/ and domain.com/

Unfortunately this only seemed to remove those specific pages and nothing else. I could remove all these pages by hand but that would be very time consuming. Is there any other way of removal all the pages for this site?

Obvious question first: when you use the Removal Tool, there's a popup with at least three options. The default is "remove page". Did you change it manually to "remove directory"?

Where do you see this popup? I went to the page linked above and I see a gray button called "New removal request". When pressed it has you type in the page. When you press continue it loads a new page with a drop down menu to select the reason (I leave it on the default "Page has been removed or blocked from search engines") and enable the checkbox to acknowledge that I need to return a 404/410 or block the page from the search engines to be permanent. After that I press "Submit Request".
