Annd boot partition on bootmgr usb drive.

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.

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?

If so open Elevated Command Prompt
Code:
 
bcdedit /store y:\boot\bcd /enum /all
replace y with actual drive letter. Post output

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?
