After installing ubuntu to my machine (Acer Aspire F5-572G), UEFI is unable to detect grub as the boot manager. The closest answer to fixing this is Unable to install Ubuntu on Acer Aspire ES1-533.

The issue is that this solution above proposess sudo apt-get install --reinstall grub-efi-amd64. However my machine is of Intel 64 bit architecture.. and not AMD.. When preforming apt-cache search grub-efi it provides the possible packages:

grub-efi
grub-efi-amd64
grub-efi-amd64-bin
grub-efi-amd64-dbg
grub-efi-amd64-signed
grub-efi-ia32
grub-efi-ia32-bin
grub-efi-ia32-dbg

Since my computer is Intel 64-bit arch, I'm not completely sure of the consequences either installing a ia32 or amd64...

Hence I am wanting to know:

  • Would amd64 bit work?
  • Is there any risk to choosing ia32 with 64 bit archeture?
  • Any other possible method of getting grub noticed by UEFI?

Note: I have wiped hard disk recently and able to reinstall ubuntu to hard drive if anything breaks :)

If you installed the 64 bit ISO:

sudo apt-get install --reinstall grub-efi-amd64

If you installed the 32 bit ISO:

sudo apt-get install --reinstall grub-efi

Theoretically 32 bit apps should run fine on 64 bit architecture, but will only run at 32 bit speed.

You may also want to look into running Boot-Repair.
