I ran into a problem with a brand new motherboard and UEFI BIOS. I have
ASUS M5A97 with AMD 4 core FX4300
It was driving me nuts because the install would appear to run OK yet it would never boot. Here is what I found and it looks like a bug in enumerating UEFI BIOS.
If I let the install create partitions I would see it try to install onto the audio device! (You read that right) What I see is
format device mapper volume /dev/mapper/isw_cfdjdifcbj_Audio-part5 (398 MB) for /boot with ext4
and similar for the other partitions. It make no difference if I disable the onboard audio or not. This is what the install is doing. If I go and delete all the partitions and recreate them on the only hard drive then it works fine. I also notice that the drive enumeration is really flaky as it sees the audio device as a disk and it sees the only hard disk twice, once as standard sata drive and again as a RAID drive even though there is no RAID controller or RAID option present. I went through the BIOS and disabled as much as I could but the error always occurs. IN a nutshell all automatic installations will fail. A quick note and that was that I wondered if it was the platform but WIN8 and Server 2012 installed without a hitch. I guess my only question now is if I got the right partition sizes. I don’t know much about Linux partitions but what I created is as follows
and 20 GB for swap
Do these look right and if not what should I adjust them to. Any advice is appreciated.
