Sorry, I did an approximate translation from French.

The message is :

error: failure reading sector 0x0 from 'hd6'

Press any key to continue....

The DVD drive is empty. When there is a DVD in it, no error.

I already changed the order of the sata connections to have the DVD drive as the latest one.

Thank you.

I just bought a new configuration. The motherboard is a Gigabyte GA-Z87-HD3.

It provides a dual boot.

In Legacy Bios, some issues around video, but I would rather be in UEFI mode.

In UEFI mode, there is an disk issue.

After choosing the kernel to boot, Grub displays a line : */error readind sector
0x0 on (hd6)/*.

Please show *exact* message. The above does not exist.

*/Please press any key to continue

/*After pressing a key, booting process continues perfectly*/.

/*hd6 happens to be a sata DVD drive. It seems the search instruction looks for
all disks, even after finding the right one.

How do you know it finds the right device before looking at DVD?

How to tell grub to ignore this drive ?

You can't, but I expect it to ignore errors during scan. Right now I'm not sure what exactly prints this error.

Thank you,
