LVM cache in Fedora

From the man-pages: "The cache logical volume type uses a small and fast LV to improve the performance of a large and slow LV. It does this by storing the frequently used blocks on the faster LV. LVM refers to the small fast LV as a cache pool LV. The large slow LV is called the origin LV. Due to requirements from dm-cache (the kernel driver), LVM further splits the cache pool LV into two devices - the cache data LV and cache metadata LV. The cache data LV is where copies of data blocks are kept from the origin LV to increase speed. The cache metadata LV holds the accounting information that specifies where data blocks are stored (e.g. on the origin LV or on the cache data LV). Users should be familiar with these LVs if they wish to create the best and most robust cached logical volumes. All of these associated LVs must be in the same VG."

Assuming LVM is already setup in HDD (e.g. from anaconda) and SSD is untouched.

Lenovo Thinkcentre M92P
When booting to USB installer disk installation proceeds as expected
1962 no operating system found
When booting into preview mode all disks load without issue, so its not the cable
Secure Boot option either not present or disabled
Last time I fixed this by adding a fake line to the boot loader from instructions on the web
Got a warning during installation about UEFI mode
Windows Fast Startup disabled
