I'm attempting a clean install on a new hd on Dell XPS 8900 i7-6700, but installation fails at "Preparing to install Ubuntu" with an error message "ubipartman failed with exit code 10".
I can boot from the usb stick, but installation won't start from there either.
I've tried switching to ACHI, turning the secure boot off and adding 'nodmraid' to cli boot after 'quiet splash' before double dash in various combinations.
Any help or insight?
Pressing Esc or F6 has no effect in UEFI boot. I tried changing
linux /casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity quiet splash ---
to
linux /casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper only-ubiquity quiet splash nodmraid ---
in the UEFI boot options, but it didn't help. This seems to be different than the 12.10 ubi-partman case.
