Ubuntu refuses to load after a successful installation

Question

I installed 14.04 with default settings and when I turn off the laptop and turn it back on, Ubuntu refuses to boot up, instead asks me to insert a Boot Device.

Here's the paste text from the boot repair: http://paste.ubuntu.com/7464628/

The machine is Toshiba C55-a-1m7.

How do I fix this? Thanks!

You are still in UEFI mode right? Your setup looks OK for a secure UEFI boot. — ubfan1, May 14 '14 at 22:00
No, it says "Boot mode UEFI" or something similar in BIOS. I should mention I am installing 14.04 — user280052, May 14 '14 at 22:20
Check the bios settings mentioned in answers to Install Ubuntu in UEFI mode (unable to boot from USB) — bain, May 14 '14 at 23:34
Also, you did use the amd64 install of Ubuntu 14.04, and not the 32-bit version? — bain, May 14 '14 at 23:35
I used the 14.04 amd version, the BIOS settings are similar to that link (disabled secure mode, UEFI boot), not sure how to check for BIOS upgrades actually. Please help, I am this close to buying a Windows 7 installation tomorrow since I am leaving for a trip and it's 2AM here. — user280052, May 15 '14 at 00:20
I've also tried this and it gave me a few errors about blocklists and GPT: http://ubuntuforums.org/showthread.php?t=1633758 — user280052, May 15 '14 at 00:31
When I use the boot-repair tool, and go to the advanced options the GRUB location is greyed out... might help — user280052, May 15 '14 at 00:35

Solution: first post from this thread: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=708430

Use a live CD and replace "debian" with "ubuntu"

mkdir /target
mount /dev/sda2 /target
mount /dev/sda1 /target/boot/efi
mount --bind /sys /target/sys
mount --bind /proc /target/proc
mount --bind /dev /target/dev
chroot /target

cd /boot/efi/EFI
mkdir boot
cp debian/grubx64.efi boot/bootx64.efi

I also had to add sudo in front of all commands up to "chroot".

Thanks for directing us to this. I'm not sure if it's required, but I also see instructions about unmounting those directories before rebooting. https://wiki.debian.org/GrubEFIReinstall – Jacob Wan Feb 20 '15 at 05:04
