"Unable to install GRUB in /dev/sda" when installing GRUB
- by vicban3d
I recently bought a shiny new Lenovo Yoga 2 Pro and I want to dual boot it with Ubuntu for studying purposes. Its built-in OS is Windows 8.1 and it has a 256GB SSD.
I've made a separate 90GB partition just for Ubuntu and a live USB to install it.
The first time everything seemed to work great, I solved the wifi issued by blacklisting ideapad_laptop, the installation went flawlessly and Ubuntu worked fine.
When I got up the next morning and turned on my laptop it booted into Windows right away without ever showing the GRUB menu. So I tried to reset, and checked my partitions with the Disk Manager and everything looked fine. Since I couldn't find a solution online I went ahead and formatted the partition to try and install again. This time and every time since, the installation was aborted and I got a fatal error saying:
Unable to install GRUB in /dev/sda
Executing `grub-install /dev/sda` failed.
This is a fatal error.
Can anyone please suggest a solution to this problem?
If any further information is needed I would be happy to provide it.
Thanks.
When installing I get the following in details:
ubuntu kernel: [ 1946.372741] FAT-fs (sda2): error, fat_get_cluster: invalid cluster chain (i_pos 0).
ubuntu grub-installer: error: Running 'grub-install --force failed.
