When I try to update to 1.48 I successfully create a USB key but when I try to boot from it the BIOS states that it cannot find OS on it (I see that \EFI\Boot\BootX64.efi is present).

How did you build the USB stick?

It isn't a method I have used, so I cannot help. Perhaps, someone else can assist.

I have not experienced this myself (I run the binary update from within Windows) but the first thing I would check is the file system on the USB flash drive.
Has it been formatted with FAT32? The UEFI spec only supports the FAT (FAT12/FAT16) and FAT32 file systems.

Try turning the bootable (active) flag OFF. It isn't necessary for EFI booting and may be confusing BIOS into trying to boot in legacy mode.
Doubt it, but it' s worth a try.
