October 23, 201213 yr Hardware listed below. I have been running Unraid with this hardware for a year with 11 drives with no issues. When I add the 12th drive the box fails to find a bootable device. I have tried some of the suggestions on the wiki but I am failing to find a combination that gets by the 12 drive issue. I am looking for a bump in the right direction. I know other people are using this mobo with no issues. I would like to the learn correct way to prep the usb drive to work with 88GM-LE. I am sure it is an operator error on my end. Any help would be much appreciated. Things I have tried: USB Prep FAT and FAT32 format done from windows 7, then copied unraid, ran make_bootable.bat as admin on multiple USB drives FAT and FAT32 format done from windows 7 on multiple USB drives using the HP Format Tool , then copied unraid, ran make_bootable.bat as admin on multiple USB drives [glow=red,2,300]UPDATE:[/glow]used make_USB-FDD_compatible_unraid.bat on the USB drive, it still showed up as a USB device.

October 24, 201213 yr In the last picture of your second post, select the USB drive and move it to the top of the list. Instructions (partial and not really clear) on how to do this are on that screen. You may have to play a bit to figure out how it really works...
October 24, 201213 yr Author I did try selecting "USB:Kingston DataTraveler" and hitting pressing Enter. but I got the same result, no bootable media found. I will try using different key combinations tonight to move the usb drive to the top of the list.
