How can I delete a dual boot operating system?

Tyharo
I tried the windows 8 developer preview and set it up as a dual boot. Today I got tired of it and decided to get ride of it so i deleted the partition it was on. Now when I boot up It still appears in the list of operating systems i can boot to. How do I delete window 8 developer preview from my boot selection?

    1. Right click 'My Computer'
    2. Go to 'Properties' on the pop up menu
    3. Go to the 'Advanced' tab on the system properties menu
    4. Click on the 'Startup and Recovery' settings options
    5. On system startup down arrow, select your default operating system (Which should be something like this: "Microsoft Windows XP Professional" noexecute=optin /fastdetect
    6. After selecting default operating system, unselect the Option 'Time To Display List of Operting Systems'
    7. Click on Ok.
    8. Again click on ok to close menu and restart your machine.

    Hope this helps.
    Cheers!

    You could always use EasyBCD to alter your boot menu options. It is simpler than using the command line BCDEdit to do the job on Vista/7 or editing boot.ini with XP.

    Agree, EasyBCD is great to use for all kind of installed systems and bootloaders.
    Now also with support for virtual drives. Only one drawback, it's mainly for new OS which has a BCD store in saving all settings. Meaning from Windows Vista and ahead.

    Hi, what happened in your case is quite common for lot of users.

    Well I'll tell you.
    When we want to get rid of installed systems we can use the commandline prompt (cmd.exe) with diskpart. Or we can use the gui Windows tool Disk Management.
    Even possible to deal with this by using third party Partition manager software.
    Most of users meet this problem as they believe it'll be enough to delete the specific volume from the harddisk, yhea that would be sweet.

    Let's take a look, what many can't see is that the bootprocess during a computer starts up using something which called Bootloader. It follow a quite old rule since long time back together with Bios together with MBR and the Bootsector on the harddrive. Now we on our way moving over to start using UEFI which will change much in how it's used.
    Anyhow, there is almost as many different types of bootloaders as there is operating systems on the market. By installing a system on the harddrive it also installs a bootloader, orelse it doesn't got what helping the system to starting up. A technique simply called bootstrapping and it hasn't almost not changed that much since the first computer arrived to us, not until now by the help of UEFI and if the system having support for it like Windows 8, it also depends on the hardware if it will work. What we've heard from the keynotes and Windows 8 IT IS ONLY computers which supporting UEFI in the hardware that will boot up in 8 seconds or less. Not other older machines.

    Bootloaders can be tricky as they saves their code both in the bootsector on the harddrive and also like files somewhere, in case of Windows often inside the first volume on the disk. In your case when working with Windows there's several alternatives in change these settings.

    1. We can call up the Startmenu -> Run -> sysdm.cpl and change the settings for default system that should boot and also DELETE the former system which shouldn't be there. It will replace the bootloader to the one we want to choose.

    2.We can use the System Configuration tool - Startmenu -> Run -> msconfig.exe
    On the Boot tab we able to switch default booting system and also DELETE the former system in the list. It will replace the bootloader to preferable.

    Beyond these two above there is two other alternatives pending on we need to doing it from inside the system or from the outside (offline mode). By the last one we using the Windows Recovery Environment (WinRE) which is found on the Windows DVD. It's also possible make a own new copy from inside Windows by burning and prepare this tool on CD if doesn't have a genuine Windows disc reachable. In both these cases I believe the best way is in using the commandline and working with commands in switching bootloaders with 100% result.
