UEFI Build Test

I've created 3 partitions on the disk... Screenshots after the error
- The EFI partition tried both EFI (cannot select for loader) and Bios Grub (selected for loader)
Grub error on both
- A swap partition
- A root "/" partition

LL files/OS appear to install ("/" has typical LL file structure) - Grub portion fails...

firenice03,

In case you weren't aware, you need to set a mount point for the "EFI System Partition" during install -- I think that might be why grub failed to install.  On partition selection page after choosing "Something else", highlight the 550MB FAT32 partition, click "Change" button, then:

• "Use as" = EFI boot partition, (or similar wording).  I believe selecting that will automatically make installer know that the mount point for the partition is "/boot/efi"; but if you do see a separate box for "Mount point" after filling in the "Use as" box, fill-in as seen below.
  
• "Mount point" = /boot/efi  (this step may or may not show -- see above)
  
• Keep size as-is
  
• Hit "OK"
  

Then you should be able to select "/dev/mmcblk1pt1" as "Device for boot loader installation" near bottom of window and grub should install properly.


Incidentally, (just for information purposes), attempting to install grub to that partition as "bios_grub" probably failed for one of several possible reasons (most likely one being listed first below):

• If you're live dvd/usb is booted in UEFI/EFI mode, it won't use a "bios_grub" partition, even if you try to point to it.  That partition is only used for Legacy/Bios mode installs to a GPT disk.
  
• If you were booted in Legacy/Bios mode for the install (doubtful in your case), that partition needs to be "unformatted", (not FAT32), and the "bios_grub" flag needs to be set on it.
  
• In Legacy/Bios mode install, "Device for boot loader installation" should be directed to the MBR of the drive, not to the "bios_grub" partition.  (Eg.  to "/dev/mmcblk1" in your screenshot, not "/dev/mmcblk1pt1".)

Thanks gold-finger.. I'll give it a few more go's = I won't be able to get back to it till this evening..

I tried installing as both EFI and Bios_Grub from the options...
- If I recall when choosing the EFI option, it didn't allow me to enter a mount point (/boot/efi) and I believe "/dev/mmcblk1pt1" wasn't a choice for "Device for boot loader installation"
The screenshots were after the error and restarting the installer ...

I tried various ways; even a clean wipe, formatting the efi partition in Windows assuring a gpt/efi partition was wrote to the disk..

I'll capture screenshots of the configuration as I move through the installer...

Thanks again!!
