August 15, 201312 yr My motherboard is an ASUS P7P55D-E Pro. 8 onboard SATA are all filled, and I have a 4-port Promise PCI card. If I fill all 4 SATA ports on the PCI card, my USB drive no longer shows up as a boot option in the BIOS. The only way I can boot off USB again is to unplug ANY of the drives, it doesn't matter which one. In the BIOS, USB is configured to boot as a hard disk (tried booting with other options, unRAID would not load as anything else, CD rom/Floppy/Forced FDD). If I have all 12 drives plugged in, the USB does not show up as a bootable device in the BIOS. If I unplug any of the drives, it shows up again. Does anyone have any experience with a similar issue, or with this board in particular?

August 15, 201312 yr Did you check with ASUS for BIOS updates and contact Tech Support to see if they had a solution?
August 15, 201312 yr Author Did you check with ASUS for BIOS updates and contact Tech Support to see if they had a solution? I did update the BIOS, but their most recent update for this mobo is from 2011... their tech support has told me in the past that they do not plan to officially support Windows 8 with this motherboard, so I'd be surprised if they release any more updates.
June 20, 201412 yr Hi.. sorry to revive the old post.. but i have a partial solution and i will post for future victims of this problem I have a P7P55D and the same problem, with 12HDDs you can't select the USB as first boot. In my situation the Unraid is a VM inside ESXI. So when i installed ESXI on USB and add the 12 HDDs can't select the USB to boot, the same problem with baremetal Unraid and 12 HDDs. Well... to my surprise if you select NOT INSTALLED on each of the SATA PORTs of the onboard controller (the one with 6 sata ports), this disks are not showed in the list of booteable devices, so you can select to USB to boot, BUT ESXI RECOGNIZE THEM, EVEN IN THE BIOS WERE "NOT INSTALLED", AND I CAN USE THEM FROM THE UNRAID VM. I don't try to boot Unraid baremetal, but perhaps work the same way... it's worth to try... Another approach is to install PLOP in one of the HDDs to redirect the boot to an USB drive. I dont know if you install PLOP on an HDD has a interference with UNRAID, i suspect not because UNRAID check the ReiserFS and PLOP stores in the partition table... I assume you need to first create the unraid system with less than 12 HDDs, then install PLOP in one of them, set as first boot, configure PLOP to USB boot, boot Unraid, then install the other HDDs. Cheers
