From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

One possibility is that it has a degenerate UEFI implementation that will only recognize the efi "payload" if it's in the fallback location—I had this problem with an older HP laptop. You can force
grub-installto place the needed file in this location by passing the--removableswitch (you may also need to pass--efi-directory=[dir]), or you can manually copy the file toEFI/BOOT/BOOTX64.efion your EFI partition if it was already installed elsewhere.If you're getting a grub command line, then it's finding the grub efi payload itself now, but can't locate the kernel (or possibly the initram or something that's supposed to be in it). Check your grub.cfg and try to confirm that it's looking for the correct partition on the correct drive.
