Windows 7: BCDEDIT - How to Use

Won't that also delete Entry #2? They both seem to have the same BCD ID for some reason...

I've just noticed my mistake. The BCD IDs are different by a single digit:

Code:
Entry #2
 Name: Windows 7
 BCD ID: {57bc9ba3-7768-11de-8d7f-bc29a8a8e033}
 Drive: C:\
 Bootloader Path: \Windows\system32\winload.exe
 
 Entry #3
 Name: Unnamed Entry
 BCD ID: {57bc9ba2-7768-11de-8d7f-bc29a8a8e033}
 Device: unknown
 Bootloader Path:
I'll try deleting the erroneous entry tonight and let you know how I get on.

I'll also post the error message from EasyBCD if I get a chance.

This highlights a very important point. When using this tool (or an equivalent that does the same job), be extremely careful when typing in ID strings especially when deleting entries. A mistake here can cause problems necessitating in the reinstallation of your system.

Agreed!

I thought that EasyBCD was kicking out errors because the two BCD IDs were identical. Now that I've realised that they aren't identical, I don't know whether to be more or less concerned!

OK, so the EasyBCD error message pops up when I go to Edit Boot Menu, and try to delete the third menu item.

The message reads:

Code:
Unhandled exception has occurred in your application. If you click Continue, the application will ingnore this error and attempt to continue. If you click Quit, the application will close immediately.

Object reference not set to an instance of an object.
And the contents of the Details tab:

Code:
See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

bcdedit /delete {57bc9ba2-7768-11de-8d7f-bc29a8a8e033} did the trick!

Hi Guys!!

Sorry about my English
I have a question!

How can I use two Hard drives. The situation is: I have HP Dv7 and the owner of it wanna have it with Windows 7 and Windows XP. The laptop has two hard drives, and the bios doesnt suport to choose what drive to boot up. It only starts up on the First drive. Now I have the first drive with Windows 7 and the second with Windows XP. I did try to use easyBCD but didnt work. I tried to set it to boot Windows XP on Drive "D:" on easyBCD but didnt starts up. Only starts Windows 7.
Is there any way to do That??

Thanx in advance!

Thanx for your reply!!

Is there any method to do that in diferent hard drives insted of diferent Partitions? without installing windows 7 after. I have Windows 7 installed in the first one Hard(500gb) drive and Windows xp in the second one Hard drive(160gb), not just partitions. I tried to setup with easyBCD but it shows me C:, D: and Boot options, not Disc0, Disc1 like when you go to Linux Tab options.

Linux Tab


Windows Tab


EasyBCD View Settings Button


EasyBCD View Settings



Thx a lot
