I have an idea of what is causing your problems, but need to confirm a few things first. Please answer all of the following questions.
1. As I understood it, you originally installed LL in Legacy mode, then followed instructions in video posted by Jerry to convert the install to using UEFI mode. Is that correct?
2. Once converted to UEFI mode, were you able to boot into both Windows and LL without needing to toy around with UEFI boot settings? (You could keep computer set to boot in UEFI mode and successfully boot into both OS's, correct?)
3. When booting in UEFI mode, did you see a grub menu on boot and were you able to successfully boot from that into both Windows and LL?
4. Once you got LL working in UEFI mode, (if you can remember), approximately how many times did you shutoff/reboot computer before the boot problem with LL happened?
5. Did the LL boot problem coincide with having done any system updates? Or was it only a problem once you tried to setup the binding to DATA partition?
6. Can you still boot into Windows without any problem and if so, are you using its entry shown in grub menu to boot into it, or are you booting to it some other way?
General observations from your posted output:

General observations from your posted output:
- "bios_grub" partition shown in parted -l output. Assuming UEFI conversion worked, that's okay -- it's just left over from original legacy install and is not being used any more. (Should not be the cause of your booting issue.)
- I was expecting to see an entry in the fstab file for the "EFI System Partition" -- but there is none. That very well could be the cause of boot problem. (But, since I don't have a UEFI system to test, I'm only pretty sure of this -- but not 100% sure.)
- Currently your /mnt/DATA mount point and all directories on it are owned by Root. This will need to be changed, but don't worry about that right at this moment. Get back with answers to above questions first, before trying to mess with changing ownership on anything. (Don't attempt changing ownership yet.)
