Just tested on a non-softraid installation. Same exact issue, same diskinfo values.. I also tested that legacy boot works OK. FWIW, here are the machine diskinfo when bootin non-UEFI: Disk BIOS# Type Cyls Heads Secs Flags Checksum hd0 0x80 label 972 255 63 0x2 0xe16a9f7f hd1 0x81 label 1023 255 63 0x0 0xc03b08e9 > > In the meantime, this is the current machine diskinfo (using usb with > > softraid) output and dmesg below. > > -- > > (Wiriting this off the screen) > > Disk BlkSiz IoAlign Size Flags Checksum > > hd0 512 0 14GB 0x4 0xef39964e Removable > > hd1 512 1 29GB 0x0 0xc03b08e9 > > hd2 512 1 4MB 0x0 0x783601b2 > > hd3 512 1 4MB 0x0 0x787e01b3 > > hd4 256 1 4MB 0x1 0x0 > > hd2, hd3 and hd4 doesn't seem to be a normal disk.

Ignoring the disk at least lets me boot.
