Windows 7: Can't get rid of the dual-boot option on start-up - any thoughts?

Can't get rid of the dual-boot option on start-up - any thoughts?

I've been finding the answers to all my problems on these forums, but I wanted to double-check the proceedings before I do anything drastic.

Pic of Disk Manager + Easy BCD

Essentially I installed Windows 7 to a 2TB HDD because I thought I would have to update the firmware on my SSD drive before installing windows there, but it turned out the SSD was already up to date. So I installed Windows 7 on the SSD, and in the process I formatted the 2TB drive. However, the 100mb "System Reserved" partition remained and I've been a bit apprehensive about getting rid of it in case it's still needed.

The problem is that when I boot I get a screen asking me to select between two versions of Windows 7, but obviously only one of them works. I've tried EasyBCD but it only shows one OS installed (which is true), and changing the count-down time option doesn't make any difference.

Any thoughts on how to remove the dual-boot option? Can I just delete the Reserved Partition and everything will be fine? I've checked in the BIOS and the only disk in the boot list is the SSD.

Many thanks,

Dan

It would have helped if you had asked beforehand since we solve these issues every day and could have saved you a lot of trouble.

Unplug the 2tb HD, if possible swap its cable to SSD so it is in DISK0 slot.

At boot enter BIOS setup to set SSD first HD to boot.

Boot the Windows 7 installer System Recovery Options or System Repair Disk to run Startup Repair - Run 3 Separate Times until Windows 7 boots and holds the System Active flags.

You can then plug back in the larger HD, boot again into the Windows 7 installer, choose Custom install, then use drive options to delete the 100mb System Reserved partition, close the install window and reboot computer.

Or you can use free Partition Wizard bootable CD to delete the 100mb partition and even Resize the partition to it's right into the unallocated space.

Start menu - run - type in msconfig - click the BOOT tab - delete the OS you are having problems with



Be sure to delete the right one

Hey mangoh - there's only one boot option in msconfig, otherwise I would have tried that already :P

Gregrocker - cheers, I'll give these steps a go. I'll have to do it at the weekend though as I can't afford any down-time if there are issues. Thanks for your help!

Here's another option

1. Open up the command prompt and type “bcdedit”. As an Administrator.


2.Basically you will now get a lists of all the OS's that are registered to the Windows bootmanage For instance, as you can see, there is an entry called “Windows Legacy OS Loader”, the identifier of which contains the value “{ntldr}”. From this, I can tell the WindowsLegacy OS Loader used to load Windows XP on this system, since the value of ntldr is default for winxp boot-loader.


3.Now type bcdedit /delete {ntldr} /f
remember to type it as you see it here with all the spaces. Also if you right click the command prompt ans select mark it will allow you to copy the correct identifier for later use.



4.After you see the message “The operation completed successfully”, restart your computer. And you will no longer see this boot option screen anymore.


All the best and happy modding
