Hi!
I'm struggling with my lenovo m720q to boot on internal SSD (PCI NVME) with 22.1.
it was working fine for months before with older version.
Install works fine but I tried several bios & install settings without success: when reboot, it says error 1962, no operating system found (boot loop).
I though ssd was dead so I tries a new one: same issue.
As a temporary work around it does boot and reboot fine with installation on external USB HDD (an old 80GB I had in my drawer)
ideas welcome...
