So i'm trying to install Ubuntu on my laptop, it seems to work fine until it tries to install grub. I haven't seen progress the past hour and this is the second attempt.

I'm trying to install 13.10, using a Linux Live USB. I don't care about the contents of the laptop.

I've been trying to find instructions about installing grub before starting the installation, hoping that would solve my issues, but I came up empty.

Laptop is 2 years old, it used to run dual-boot windows 7 and Ubuntu. I'm now doing a fresh install of just Ubuntu.

I hope anyone knows how I can find out why it is happening.

  • Could you describe your partitions and error message if anyone is shown.

  • I haven't seen any error message. I just rebooted to get you the partition info, currently it shows me 3 partitions: 510MB efi, 495GB ext4 and 4 GB Swap. at /dev/sda1 through 3.

During the installation, there's a way to skip installing grub. Look at the "Device for boot loader installation" dropdown.

Instead of choosing the entire device "/dev/sda", choose the partition you'll install Ubuntu, such as: "/dev/sda1"

Device for bootloader installation dropdown menu

If you choose "dev/sda", you're supposed to rewrite the boot record for the entire drive, which I believe is what's your issue is all about.

But when you choose "dev/sda1" (or sda2,sda3...) you get to place the boot flag at the beginning of the partition, not the entire drive. That does not make you go for a change in your bootloader. In other words, you place a boot flag as a "subtitle" to your pre-existing bootloader.

After you apply the fix, if you ever want to switch to Grub2 for any reason, use the Ubuntu Boot Repair disk: Ubuntu Boot Repair

If all else fails, try to "rewrite your MBR" because during your uninstallation of Windows, its boot sector may have accidentally remained there. Since you are doing a fresh install of Ubuntu, this may stand as the final option since there's a small chance that Ubuntu failed to handle your Windows partition's boot flags correctly.


In case you have issue when installing on UEFI BIOS (not sure if this issue is adressed only to Acer Laptops) there is a topic here that helped me solve this issue.

I will copy the commands in case it disappears, but all credit goes to Pueseso from Acer Community forum.

-- Boot Ubuntu Live USB
-- open terminal
sudo -s
ubiquity -b
-- Press Continue testing after installation is over.

--Now we will return to the CLI (  https://wiki.debian.org/GrubEFIReinstall  )

sudo mount /dev/sda2 /mnt #sda2 is the root partition
sudo mkdir /mnt/boot/efi
sudo mount /dev/sda1 /mnt/boot/efi #sda1 is the efi partition
for i in /dev /dev/pts /proc /sys; do sudo mount -B $i /mnt$i; done

modprobe efivars # make sure this is loaded

-- notice the bootx64 file
efibootmgr --verbose

-- We will reinstall grub-install for a 64bit version
apt-get install --reinstall grub-efi-amd64

grub-install —no-nvram —root-directory=/mnt
chroot /mnt
cd /boot/efi/EFI
cp -R ubuntu BOOT
cp grubx64.efi bootx64.efi

-- You are finished, reboot the system.
