GRUB: “invalid arch independent ELF magic” after install on SSD

I am currently trying at get a dual boot computer to work, where the Ubuntu 12.04 operating system is spread over two drives.

The setup of the two drives are:

HDD:
_{/dev/sda1 /boot/efi
/dev/sda2 some unknown msftres at 128MB (don't bother about this as long as the rest works)
/dev/sda3 Windows 7
/dev/sda4 /home
/dev/sda5 swap
/dev/sda6 /tmp
/dev/sda7 /var}

SSD:
_{/dev/sdb1 /}

In an attempt to combine speed with SSD durability. That might be a topic in itself, but for now I would be very happy just to get the grub bootloader to work.

When booting at either HDD or SSD, I get this error:

error: invalid arch independent ELF magic.
grub rescue>

Answer 1

I had the same problem “invalid arch independent ELF magic”.

I was installing from a USB stick booted from the Bios in UEFI mode.

After a couple a couple unsuccessful reinstallation of 12.04,I tried the same installation with the the USB stick booted without the UEFI mode and it works.

For your information my setting on a 120GB SSD

sda1 /windows 90 GB windows 7 64bits

sda2 /boot 100 MB

sda5 swap 1 GB

sda6 / 18GB ubuntu 12.04

sda7 /home 8GB

My motherboard is P8P67 Pro with Asus EZbios and I had two choices in my boot menu for the USB with 12.04 installation.

Hope it helps!

I have fixed the same problem with Backtrack on VMware the boot was broken after installing vmware tools.

I used the following commands :

sudo mount /dev/sda1 /mnt

then

sudo grub-install --root-directory=/mnt /dev/sda
