<p class="MsoNormal"><span style="font-size:11.0pt">Hi folks,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I was installing StarlingX in a NUC with 2 NVME disks (without other HD or SATA disks), and the installation was ended up with an issue as follows:<o:p></o:p></span></p>
<p class="MsoNormal" style="text-indent:.5in"><span style="font-size:11.0pt">“ERROR: Specified installation (<span style="color:#C00000">sda</span>) or boot (<span style="color:#C00000">sda</span>) device is a USB drive.”
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">It seemed NVME disk was not recognized as valid boot disk.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">With the help from @Saul, we found in “bsp-files/grub.cfg”, “boot_device” and “rootfs_device” were by default set as “sda” in ks cmdline:<o:p></o:p></span></p>
<p class="MsoNormal"><i><span style="font-size:11.0pt">linuxefi /vmlinuz inst.ks=hd:LABEL=oe_iso_boot:/smallsystem_ks.cfg
<span style="color:#C00000">boot_device=sda rootfs_device=sda</span> biosdevname=0 usbcore.autosuspend=-1 console=tty0 inst.text inst.stage2=hd:LABEL=oe_iso_boot inst.gpt security_profile=standard user_namespace.enable=1<o:p></o:p></span></i></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">So, there are 2 ways to make NVME disks work as boot disk:<o:p></o:p></span></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoNormal" style="mso-list:l0 level1 lfo1"><span style="font-size:11.0pt">to change the grub cmdline, with “nvme0n1” for “rootfs_device” and “boot_device” accordingly, during the installation.<o:p></o:p></span></li><li class="MsoNormal" style="mso-list:l0 level1 lfo1"><span style="font-size:11.0pt">Not to set “rootfs_device” and “boot_device” in ks cmdline, and let “bsp-files/kickstarts/pre_disk_setup_common.cfg” detect “nvme0n1” dynamically.<o:p></o:p></span></li></ol>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Though, I wonder if there are other better ways in such a case.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Regards,<o:p></o:p></span></p>
