For your information, I tried to boot from the windows 7 DVD but it's not even seen when I press option Key at boot (tried C key also)

Hi,

thanks again,

Installed.

Just for your information, I tried to boot from a windows 7 DVD made from an iso, it didn't work.
In mac os the disc is seen as empty, maybe I wrote it bad.

I also already used gptdisk following the topic mentioned in first post.

I won't make any modifications before your answer

Thanks again for your help

Hi,

i won't have access to it until monday.

But the steps in your topic are pretty similar to what I already did in the one I mentionned and where you already were the saver

No bootable device after changing partitions

It dit make bootcamp appear back in the option menu but windows can't boot telling me there's a recent hardware change.

I think the first direction you took (using windows dvd) was right but I was not able to boot from it. maybe I burnt it bad ?

Thanks a lot

Hi,

thanks again,

i still don't have acces to the mac.
I don't get you totally.
I'm pretty sure to have done the exact procedure you wrote.
(with 2 3 4 and then with 3 4 5 as answers) and could not boot.
I'm gonna try tomorrow again.

thanks

Hi,

so I tried your commands, and it's the same.

The operation has completed successfully.

It does make the bootcamp partition appear but I still have this at windows startup :

Hi thanks a lot,

that was my point since the beginning.
I found out that usb booting did not work, neither my burnt dvd.
Booted from an original dvd and it worked, just had to repair boot with the dvd tool.

Many thanks for your time.
