Hi All,

Have an M5510, 1TB Samsung  NVE SSD and another system with a SK Hynix-SSD, BIOS set at AHCI, UEFI.   Install a Windows 10 image with no issues.  As soon as McAfee Encryption begins, and I reboot, the system flashes the DELL bios image a few times and then it gets stuck at "PREPARING AUTOMATIC REPAIR".   Stays for hours with no movement.

If I switch to "Legacy" apply the Windows 10 image, no issues with McAfee at all.  

I have an XPS13 with 256gb Samsung NVE SSD.   All works fine in UEFI mode.  No issues.

Any ideas?

thanks

Paul
