Can I delete {fwbootmgr} and system will default to {bootmgr}?

{Fwbootmgr} skips {bootmgr}

I used bcdboot C:\Windows /l en-gb /s B: /f ALL from bootable USB when ASUS K55A - HI5014L magically corrupted boot information when multiple f1-12 keys were pressed at a start up. I was able to boot into win7 64bit, one of two OSs in dual-boot setup. I then recreated bootentries for {bootmgr}. However every time i restart system continues just boot straight to win7. I can't figure out how to link fwbootmgr to bootmgr.

I have tried Bcdedit /set {FWbootmgr} displayorder {Bootmgr} /addfirst

I couldn't find any info on google as to what will happen if I delete fwbootmgr, however it is an option in "Visual BCD Editor"

Edited

When I tried to set partition to ACTIVE and got an error I learned that GPT do not use Active partition. All my partitions are GPT. Also read that MBR is not related to EFI.

After messing around with bcdedit bootrec and bcdboot earlier today... I completely locked myself out. System wouldn't boot, bcdedit of a USB couldn't find data.Bootrec /rebuildbcd was identifying two installations but said "The requested system device cannot be found."bcdboot d:\windows "failure when attempting to copy boot files"

I tried to do repair of win8 USB got"required file is missing or contains errors"file: \windows\system32\winload.efi

so I cheated and used EUFI modded USB installation to install a second w7

I now have Working Windows Boot Manager that i can add entries to. But when I use EasyBCD to add simple entry like

Name: w7BCD ID: {be824de0-829d-11e3-bafc-f6ea108bac12}Drive: F:
Bootloader Path: \Windows\system32\winload.exe

the system hangs on start up..

My BCD files may be corrupted





Another Edit

I can see now what EasyBCD did wrong it added entry with winload.exe ... changed that to winload.efi and now I can boot to original w7, next tried to do that with w8 but get "windows cannot very the digital signature of this file"

BTW looked at diskpart, w7 install created a new fat32 system partition, my old 300 mb fat32 at some pointed turned into primary losing its system to a 900mb partition that came out of nowhere... so that my have contributed to mayhem...

Booted into EUFI win7 USB, bootsect went thru, but bcdboot and sfc got rejected.enter image description here

I tried label command inside \system32\ and it gave me "invalid win32" but if I ran it offC:\Users\Administrator> it'll go thru so how do I run bcdboot or sfc and have it work on specific partition because my thinking is going into \system32\ on D: partition would isolate commands used to that partition and OS.

And for offline sfc scan the /offbootdir should be the fat32 100mb where EFI is or I'm seeing thru partition manager there is also "Microsoft Reserved" 128mb is what I should have selected.
