Cannot install RancherOS - /dev/sr0 when booting by usb

[Angelinsky7]

Version : rancher/os:v1.2.0-rc2
Installation : baremetal

I downloaded the latest image, created an usb bootable disk with rufus (from window 10 with default options) and tried to install...

[rancher@rancher ~]$ sudo ros install -c cloud-config.yml -d /dev/nvme0

[rancher@rancher ~]$ blkid
/dev/sda1: LABEL="RANCHEROS" UUID="72E6-FBFF" TYPE="vfat" PARTUUID="012850b0-01"

The label is always in capital letter, i tried to change it but everytime in captial... (i know that is should be "RancherOS")
What can i do ?
Thanks for your help and os !!!

I don't have a windows, not sure whether caused by rufus.
Later I will try to reproduce it.

I am having the same issue.
Would this be related to setting up another computer with the same USB as the initial one. This is my 2nd install. The 1st one went fine. Is there anything changed on the USB after the initial that would cause the 2nd to fail?

[Shifter2600]

A little more on the issue. On the 1st machine I do have a cd/dvd drive so there is a /dev/sr0 mounted.
But on my other machines there is not. And it'sa these other machines that I am getting these errors.

[Shifter2600]

So :s I guess if you don't have a /dev/sr0 just sudo mkdir /dev/sr0 and problem solved.

I can confirm that this workaround works!

I just experienced this exact issue when trying to install Rancher OS as a KVM guest under entperise Linux. The suggested work around also allowed me to move past this issue. Just wanted to note that this is not limited to Rancher OS on Windows hosts.

I don't have a test setup, will be cool if anybody can help me to verify this issue.
Just to use rancheros v1.3.0-rc1

Fixed in rancheros-v1.3.0-rc1, below is my test record
