OPTION THREE
Using the bcdedit Command
1. Open a elevated command prompt or a command prompt at boot.
NOTE: If you have a RAID setup or a PCI-E SSD as your boot drive and want to open a command prompt at boot, then you may need to use the Load Drivers option in the System Recovery Options screen to load it's drivers first before Windows will see the boot drive to be able to use the bcdedit command on it.

2. In the elevated command prompt, type bcdedit and press enter. (see screenshot below)
NOTE: This will let you see what OS is the default to start under the Windows Boot Manager section, and to see the description (name) and identifier of the operating system(s) listed in Windows Boot Manager under the Windows Boot Loader section(s). For example, Microsoft Windows Vista (description) as {730ab458-b062-11e0-84f1-fa307df851c2} (identifier).

3. In the elevated command prompt, type the command below for a listed OS that you want to be the default OS to start, and press Enter. (see screenshot below)
bcdedit /default {identifier}

For example: If I wanted to change the default OS to start from Windows 7 Ultimate (description) as {current} (identifier) to Microsoft Windows Vista (description) as {730ab458-b062-11e0-84f1-fa307df851c2} (identifier), I would type this below and press Enter.

bcdedit /default {730ab459-b062-11e0-84f1-fa307df851c2}

4. In the elevated command prompt, type bcdedit and press enter. (see screenshot below step 3)
NOTE: This will let you see and verify the new default OS identifier to start under the Windows Boot Manager section. For example, {default} identifier for Microsoft Windows Vista (description) now.

5. When finished, close the elevated command prompt.





OPTION FOUR
Using the "EasyBCD" Program
1. If you have not already, download and install a free version of the EasyBCD program, then run it.
NOTE: The free version download is at the bottom under "Download free for limited, non-commercial use". Registration is not required to download.

2. Click on the Edit Boot Menu button, then check the box for the OS that you want to be the default OS to start in the Windows Boot Manager. (see screenshot below)

Lost Bootmanager

I installed Windows 7 on a SATA drive within an XP system, it made a nice boot choice menu. I had some issues with an XP install on C:, and reformatted... lost that nice boot menu, now I don't have access to that independent G: drive or anything windows 7 other than to see the files. It's not considered a bootable drive in Bios as it needs the sata drivers to be loaded first and short of re-installing is there any help? A simple boot loader program pointing to the drive doesn't seem to work.. but perhaps I'm not pointing correctly? A Win 7 repair tells me boot manager is missing bu there is no repair. Would EasyBCD for XP do the trick?

Helllo Ah802,

Yes, you should be able to use EasyBCD to repair the boot file by adding Windows 7 to it.

Looks like Vista is what it wants.

There are a total of 2 entries listed in the Vista Bootloader.
Bootloader Timeout: 5 seconds.
Default OS: Windows XP

Entry #1

Name: Windows XP
BCD ID: {default}
Drive: C:\
Bootloader Path: \NTLDR

Entry #2

Name: Windows 7
BCD ID: {b62341f0-ec0d-11de-933a-0026540b8e54}
Drive: F:\
Bootloader Path: \Windows\system32\winload.exe
Windows Directory: \Windows

but in the root of c: I find

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

and no boot loader on boot., so can I simply add this with notepad?

multi(0)disk(2)rdisk(2)partition(1)\WINDOWS="Windows 7" /noexecute=optin /fastdetect
