I have Windows 8 Release Candidate installed on my d:\ partition and RTM installed on the c:\ partition. I want to get rid of the RC on d. I also want the bootloader to stop prompting me about which windows 8 to start. How do I do this?

Just remove the extra OS from the boot loader as described here. Then you can just delete the files on D: or format it.

Delete the partition with Device Manager, start by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager(source). Follow these steps below, in your case you'll select D: instead of C:(edit: you can right click on the list directly). enter image description here Removing the prompt is described here: run msconfig (Windows key + R > type "msconfig" > Enter), switch to the Boot tab, select a list item named "Microsoft Windows 8" or similar and click "Delete"enter image description here

I personally think the last post is the best solution.

Thanks, I'll look it up. –  Goran_Mandic Oct 28 '12 at 21:24

If the one on C:\ is the boot drive, you can just format the D:\ partition in windows to remove the old windows installation in disk management

That's the obvious, but inconvenient solution. If all else fails, I'll do it. –  Goran_Mandic Oct 28 '12 at 21:24
