UEFI64 boot to agFM menu fails with blank\black screen and no messages (maybe with cursor at top-left) but only fails on some computers (others computers UEFI64-boot OK)

Some computers (e.g. Zyrex or Lenovo IdeaPad s145, new Acer laptops, etc.) may not UEFI64 boot to the Kaspersky Shim EFI file.

This may be due to it being blacklisted in the BIOS (perhaps in the DBx blacklist?).

UEFI64 booting may just give a blank screen, a cursor or a dot.

To fix this, we need to remove the Kaspersky shim and replace it with the agFM EFI boot file…

Either Legacy Boot to E2B Main Menu (e.g. using \QEMU_Menu_Test,cmd under Windows or a Legacy system) and use the ‘Disable UEFI64 Secure Boot (blank screen BUGFIX)’ menu entry…

OR

On Partition 2:

1. Copy the file \grubfmx64.efi to \EFI\BOOT folder
2. Make a copy of the file \EFI\BOOT\BOOTX64.EFI (if BOOTX64.KAS does not already exist)
3. Delete \EFI\BOOT\BOOTX64.EFI
4. Rename \EFI\BOOT\grubfmx64.efi to BOOTX64.EFI
