On my old laptop (legacy BIOS, MBR disk), this was perfectly possible to get working:

I turn on the computer and see the Windows Boot Manager
I use EasyBCD (or BootPart, or something else) to add an option to the BCD menu which allows me to boot into GRUB, and then into Ubuntu

I can't figure how to do this on my new laptop (UEFI, GPT disk), whether in UEFI or legacy mode.

Currently I've installed (and even booted!) Ubuntu on my laptop, but only with the help of an external GRUB (on a USB flash drive).

How can I add GRUB as an option in the Windows Boot Manager on a UEFI laptop?

(No, I don't want to change my primary boot loader. So no, I don't want to overwrite the Windows boot loader with GRUB.)

I tried to setup a "proper" Windows/Ubuntu dual-boot system, by installing Ubuntu from a USB key. However, I simply could not get the laptop to boot off the USB despite the fact that I made the appropriate changes to the boot device order in the BIOS. So I then turned to Wubi, and (to cut a long… >>> More
