Ubuntu 12.04.3 LTS installation failed. says: "GRUB installation failed"

Question

The error message is :the grub-efi-amd64-signed package failed to install into /target/. Without the GRUB bootloader the system will not boot

I'm trying to install on HP pavilion g6-2303 TX using USB.

How do I fix this problem?

Solution 1

It's a bug. /pool/main/g/grub2-signed/grub-efi-amd64-signed 1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd64.deb file rename when you burn it in CD/DVD or usb disk to grub-efi-amd64-signed 1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd.deb. As a result installation script can't find the file and failed to install grub. Quick workaround is that(if you burn iso in USB flash drive) go to pool/main/g/grub2-signed(in usb flash disk) and rename the deb file manually (add 64). Now boot from usb flash drive and run a disk check to be sure.

Solution 2

Re-installing, as Ronshere suggests, is a possibility; however, there's no guarantee that you won't run into the same problem again. Two other options are:

• Run Boot Repair from an emergency Linux disc. With any luck, this will correct the problem.
• Download the USB flash drive or CD-R version of my rEFInd boot manager. Prepare the medium and boot with it. With any luck, this will enable you to boot Linux. If this works, check to be sure that your EFI System Partition (ESP) is mounted at /boot/efi and install the Debian-package version of rEFInd. You should then be able to boot to Ubuntu via rEFInd, without using the USB flash drive, CD-R, or GRUB.

If these procedures both fail, post back with details, including the URL that the Boot Repair procedure generated.

I don't have a /pool

Um... what? Your suggested partition scheme is... wrong. /root is not the root partition, /boot will contain the actual Linux kernels so, if it is on a separate partition (which is not always necessary or a good idea), it should be a lot bigger than your suggestion. The size of swap depends on the hardware... You give no explanation for the numbers you suggest and if people follow this scheme naively they will definitely have problems!
