Bug Description

When installing Ubuntu Wily (15.10) via PXE/netboot the installer does not detect the internal disk automatically.
It will show the "Detect disks" menu for choosing a disk driver.
If one chooses "<Go Back>" to "Ubuntu installer main menu" then "Detect disks" again, then the disk is found and automatic installation continues.

Very seldom the installer detected the internal disk automatically, but i was not able to find a pattern.

This behaviour is not observed with Ubuntu Trusty and Vivid.

Hardware are Dell Latitude Laptops (E7450 and E6420) with the usual SSD harddrives.

Please let me know if you need further informations.

Thanks

Martin

Had two machines install the new image without this issue.
Tried it again right away and both failed.
Tried it again. Again both failed to detect disks.
