Thanks for the article! I spent an hour or so trying to get my standard USB installer to boot. If I hadn’t found your article I might have ended up wasting a whole lot more time.

Update: We've managed to solve the USB mystery and it had to do with 'floppy emulation' and partition position. You can read more about that here: The case of the non-booting USB thumb-drive and the Dell R620

You touched on an interesting issue in regard to the disk controller. The default configuration is with a PERC H710 that is a hardware RAID controller. The workaround of creating a 1 disk RAID 0 ‘works’ but it does not allow passthrough of certain commands (i.e. TRIM). The ‘real’ fix is order a replacement card, the PERC H310 which allows passthrough and Ubuntu will see the disks themselves and not just a ‘virtual disk’, it also supports RAID 0 and 1 if necessary. I hope that helps. Cheers!
