RARE user and assistance email list

[David Franco <>]

Hi Alexander,

I had a short, but very clarifying, VC with Frederic and it finally worked.

Frederic suggested that, as you told me in a previous mail, it would be 
better to burn a USB with the ONIE recovery image. I did so and the 
partition table was rebuilt correctly, so eventually, the installer did 
its job.

Thank you very much for your time and help,

David
