Returning to your booting problem with your new UEFI laptop ...
Like you, I had problems dual-booting either LL3.0 or LL3.2 with Win10 (HE & Pro versions) on my UEFI laptop (Asus G750) in Legacy/CSM mode.
I remember previously, having a similar problem dual-booting LL3.x with Win8.1: it's notable that I eventually got that setup working in Legacy/CSM mode by removing the SSD, and going back to using an HDD.
I might be mistaken, but my experimentation seemed to suggest that when an SSD is used with a UEFI laptop, it expects UEFI support to come with the Linux distro you want to dual-boot with.
If you want to dual-boot on a UEFI laptop, with Windows OS, I strongly recommend you try a distribution package that comes with UEFI support. In that regard, you can't go wrong with Linux Mint - it's a mature distribution.
I've found it to work flawlessly on my UEFI laptop, dual-booted with Win10, with UEFI and Secure Boot fully enabled. I still run LL3.2 on this PC but only as a virtualbox guest on the Linux Mint host. When Jerry has reached a stage where he's ready to officially release LL with UEFI support (if that's the case), then I'll return to dual-booting with LL on this laptop (setup1 in my signature below).
In passing, I should mention that a LL3.2 UEFI test build does exist: linux-lite-3.2-uefitest1a-64bit version, available at http://repo.linuxliteos.com/uefitests/3.2/
I did try dual-booting it with Win10 on my Asus G750, but didn't have luck with this and details of the problem were reported in post #106 at https://www.linuxliteos.com/forums/linux.../#msg29172
However, some others on that thread seemed to have had more luck than myself - it might be worth you having a go too, before trying something like Linux Mint, etc ...
All the best

64bit OS (32-bit on Samsung[i] netbook) installed in [i]Legacy mode on MBR-formatted SSDs (except pi which uses a micro SDHC card):
2017 - Raspberry pi 3B (4cores) ~ [email protected] - LibreElec, used for upgrading our Samsung TV (excellent for the task)
2012 - Lenovo G580 2689 (2cores; 4threads] ~ [email protected] - LL3.8/Win8.1 dual-boot (LL working smoothly)
2011 - Samsung NP-N145 Plus (1core; 2threads) ~ Intel Atom [email protected] - LL 3.8 32-bit (64-bit too 'laggy')
2008 - Asus X71Q (2cores) ~ Intel [email protected] - LL4.6/Win8.1 dual-boot, LL works fine with kernel 4.15
2007 - Dell Latitude D630 (2cores) ~ Intel [email protected] - LL4.6, works well with kernel 4.4; 4.15 doesn't work
