As written in the topic Gparted can see partitions on the hard disk, but when i install device is partition free.
I'm installing on a system with uefi and secure boot support, but they should be both disabled.
I already installed ubuntu before but single boot and all worked fine.
I'm now trying to install Ubuntu with Windows 7 with dual boot.
Windows 7 is already installed and working.
Boot info script
As you can see sda1 and sda2 exists but the installer doesn't find them
Thank you for any help you can provide me.
