Need help installing Rancher OS

Hello, I have an Lenovo TD350 with 2 Intel Xeon Processors, 64GB RAM, 5 2TB Hard drives with only RAID 0,1 and 10 available for configuration. I have tried to install to dev/sdb (raid) and when the system rebooted and the usb is removed the system doesn’t boot into any os. I need help!

Like I suggested in your other post on this same issue - I think (for now) you need to install to a separate small disk for booting the OS from, and then add your RAID as a state partition.

I havn’t had the time or hardware to work on large disk support yet.
