Hey all, Quick one hopefully. Ive got a 500GB external HDD that I created to run a multitude of recovery wims and OS installs to run from. It boots to the Windows Boot Menu (BCD) and I can select which wim to boot from. The main 128GB partition is FAT32 and all the OS wims are .swm to fit on for FAT32 and be UEFI compatible. The main wims I use are custom W10 WinRE's (x86 & x64). This all works fine using the normal 'Legacy' boot mode, by turning off SecureBoot and chaging to CSM but I am having difficulties getting it running in UEFI. I've followed a multitude of tutorials but still coming up short. Closet I've got is a BSOD stating winload.exe is broken or something to that extent. So I'm getting somewhere. I dont have a UEFI PC myself but have one here to play with, so: Q1: Is it possible to have both Legacy and UEFI boot on the same drive? Q2: How? Would appreciate any help as this is the last stage of finishing up my drive! Thanks in advance!
