My installation USB is recognised by a PureOS / Librem 15v3 laptop, but not by a Windows / Lenovo laptop.
I have copied the Qubes ISO to a flash drive. On my Librem machine I can mount the flash drive in PureOS, and access the USB at boot.
On my Lenovo machine (where I want to install Qubes OS), I cannot even mount the drive. It gives a Windows ding when I plug the device in, but it does not appear under “My Computer”. Trying to restart from USB fails.
The only odd thing I’ve noticed is that the USB is partitioned as ISO 9660 and FAT. I assume others have got this working on Windows 10 / UEFI? Any suggestions?
