How to delete Windows 10 Boot Managers?
Hi
I have reinstalled Windows 10 beta twice on my test laptop. But when I install Windows 7 now it will no more boot. I will just see a black screen.
Sometimes I event can’t format the old partitions with the Windows 7 DVD. Then I have to delete all Partitions with a Paragon recovery Linux CD. I think the problem is because the Windows 10 Boot Managers?
If yes how can I get rid of them both?
Any help would be greatly appreciated

Hi.
Boot setup, then press shift f10. A command prompt appears. Enter these lines:
diskpart
List disk
Select disk x
Clean
(x being your disk's number). Then continue with setup.

Hi,
They can be removed using MSConfig if you can boot into the OS. But if you cannot boot into the OS use EasyBCD to remove the orphaned/un-needed entries.
I would create a Bootable USB of EasyBCD and then remove the entries.

I will try the bcedit command
@McKnife
diskpart will work with Windows 7 DVD?

How can I remove it using MSConfig? I think EasyBCD will not work for me as I have Windows 7 Pro and Windows 10 Pro.

Type MSConfig into a run command, then click the Boot tab, then remove the entries for Windows Boot Manager which are listed for OS's that no longer exist.
no you don't have to.. it just means that you are defeating the secure boot procedure.. I personally don't know how to modify the UEFI bios to remove entries that are added to it other than re-flashing the bios.
Its easyer to Use EasyBCD , the 2.3 Beta Supports Win 10
If you wish to proceed with Bcdedit ... Run It in Administrator Privilege:
It will let you see what os starts as default in WBM section, you can also see the name and identifier of the Os.
Current
For example if want to Delete Windows 7 (description) that has as identifier {aaaaaaaa-bbbb-eeee-ffff-c

You didn't execute the commands.
The clean command wipes the whole disk and all boot entries with it.

EasyBCD will NOT remove entries in the UEFI bios.

or boot into a recent linux live cd and use efibootmgr to remove the entry by number, as in:
