HP EliteBook 840 G2 - macOS Catalina - Stuck on LocHB 71B4903C-14EC-42C4-BDC6-CE1449930E49

I have a HP EliteBook 840 G2 (Broadwell Laptop i5 5300u - HD 5500 - 16GB RAM), and read the OpenCore Install Guide (dortania.github.io) and made the EFI structure numerous times, checking the lot; and then resorted to finding additional pieces where possible to see if it may help in, but nothing avails and I eventually receive [EB|`B:WFDW] Err(0xE), 0 @ LocHB 71B4903C-14EC-42C4-BDC6-CE1449930E49, followed by the dreaded [EB|#LOG:EXITBS:START] 2020-12-31T17:40:45

I've already started at Kernel Issues | OpenCore Install Guide (dortania.github.io) but after combing through the troubleshooting guides recommendations, I still can't get the thing to boot into the Catalina Install drive.

Here's the boot log on paste bin: pastebin.com/zcHTamuL
