How to eliminate dual boot options ?

post #1 of 8
Thread Starter 
ok, so in an experiement I was doing I had my two SSD's raided with an OS and had my to HDD's raided with an OS. I have wiped the HDD's now, but even after clearing CMOS I still get the screen to select which OS to boot into..... HOW do I get rid of this? its annoying as if you select the one that was wiped it tells you the MBR is corrupted. I have formatted the HDD's and still cant figure out why my machine thinks it has two options for OS's

BCDedit command line tool - remove the offending boot entry

http://technet.microsoft.com/en-us/l...8WS.10%29.aspx

Quote:
Boot Configuration Data (BCD) files provide a store that is used to describe boot applications and boot application settings. The objects and elements in the store effectively replace Boot.ini.

BCDEdit is a command-line tool for managing BCD stores. It can be used for a variety of purposes, including creating new stores, modifying existing stores, adding boot menu options, and so on. BCDEdit serves essentially the same purpose as Bootcfg.exe on earlier versions of Windows...

I am trying the BCDedit tool, but not having much luck , either its not finding the two (as its already non existent) or I am doing something wrong. Both OS's were Win 7, so its gonna be tricky I am sure

When you just type BCDedit, you don't get a result displaying at least one boot entry?

I am assuming the last one is the disk I am on... since it says current ? and the top one is the small partition windows does when it installs ? so the middle one would be what needs deleted? But not sure how to do that ..

Please double check before you delete, this is always tricky to me. Here is some more in depth info on BCDedit with examples:

http://www.sevenforums.com/tutorials...t-how-use.html

Quote:
{bootmgr} = the boot manager
{current} = the OS you selected to boot at startup.
{default} = the default OS selected to boot the PC.
{ntldr} = Windows Legacy OS Loader (for windows xp)
It sounds like {default} is the old os, and {current} is the one you want to keep, currently logged into. To remove the second entry, you would simply

Code:
BCDedit /delete {default}
Messing with boot managers makes me kind of nervous because I don't often have to do it.
