Total newbie here. I want to install Ubuntu 14.04.3 alongside Win 8.1 that's already there. I'm getting the same error no matter what - "The attempt to mount a file system with type vfat in SCSI1 (0,0,0), partition #1 (sda) at /boot/efi failed.
I tried all of the following:
Selected "install ubuntu alongside windows..." - result is that
Selected "something else" and tried creating 3 manual partitions:
~45GB for root ("/") as ext4, ~17GB for swap, ~30GB as ext4 for
"/home". Result - the above error message.
Somebody had suggested partitioning using GParted and then running
installer.. Tried this too, but GParted doesn't let me partition as
"Logical".. I only see "primary".. But, even then in GParted, I
don't see an option to set "/" or "/home" etc.. So I got to do this
in the installer? If yes, then what's the point in partitioning
This feature turns a shutdown operation into a suspend-to-disk operation. The result is often filesystem corruption or an inability to mount shared partitions (including the EFI System Partition, or ESP) from non-Windows OSes.
If disabling Fast Startup doesn't do the job by itself, then I recommend you run a filesystem check on the ESP, as oldfred suggests.
Don't know if this will help much, but, when i tried to install ubuntu on a machine that had windows 7 already, I first also tried to create a "ext4" partition manually. This didn't work. Then, I tried to create a "ext3" partition manually. That did the trick. However, before completing the installation of ubuntu, the system froze a few times. Then everything worked all right.
sudo fsck.vfat -t -a /dev/sda1from live installer. With UEFI you have gpt which does not have logical partitions only primary. If you create partitions with gparted, you must use Something Else to tell installer which partition is / (root) and which is /home. It will find swap automatically.
