[Bug 733836] Re: "Error: file not found" when booting, then boots up anyway

[Philippe Le Toquin]

I just did an update from 12.04 to 14.04 and I am now having the same
issue

I get the error 3 times and after a few seconds the laptop boot properly

I tried to run grub-install but I get that error

grub-install: error: /usr/lib/grub/i386-pc/modinfo.sh doesn't exist.
Please specify --target or --directory.

I have Ubuntu 64 bits so not sure why it refers to i386

in any case that directory is not present on my laptop. Instead I have:

grub-mkconfig_lib 
 x86_64-efi


ls-al 
total 64
drwxr-xr-x   4 root root  4096 May 30 01:13 .
drwxr-xr-x 187 root root 20480 Aug 15 09:19 ..
lrwxrwxrwx   1 root root    34 May 15 20:03 grub-mkconfig_lib -> ../../share/grub/grub-mkconfig_lib
drwxr-xr-x   2 root root 36864 May 30 01:13 x86_64-efi


Strange thing is that my laptop is not efi

Title:
  "Error: file not found" when booting, then boots up anyway

Status in “grub2” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: grub2

  After dist-upgrade to development natty I get an error right after
  choosing the kernel in Grub2 menu.

  Error: file not found

  It first seems as if it will not be able to boot, but after a short
  time (>1min) it continues to boot anyway.
