Annd boot partition on bootmgr usb drive.

Do you want that in case you wanna reinstall win7?

Is there a file \boot\bcd on partition 3? maybe it's a hidden system file!
How did you fill partition 3? just by drag and drop file from installation dvd, or extracting an installation ISO?

Is there a file \boot\bcd on partition 3? maybe it's a hidden system file!

If so open Elevated Command Prompt

Code:

 
bcdedit /store y:\boot\bcd /enum /all

replace y with actual drive letter. Post output

Bonjour, je viens d'installer windows 7 sur un disque USB, sur celui-ci se trouve aussi une partition avec l'installation de windows 7.

Pour faire simple, j'aimerai rajouter dans le bootmgr de windows 7, le choix de démarrer soit Windows 7, soit l'installation de windows 7

HDD USB :
partition 1 (100mo, system)
partition 2 (windows 7)
partition 3 (install windows 7)
partition 4 (data)

Merci de votre aide.


(in english i try)

hello, i just have install Windows 7 i86 on a hdd usb. On Hdd i have a other partition with DVD installation windows 7 boot.
I will change my bootmgr to add the boot install partition. how ?
Thx for help.

If I understand right you did put install dvd on usb. After that you installed win7 on usb disk. correct?

Which partition is active now, see disk management?

• It's possible to boot from another partition
• It's impossible to boot win7 from usb

I think typing english is a problem as well... sorry
