Dual Boot & UEFI -- another lost soul

[okie2003]

In Post #6, you said you had this partition:
100 MB Healthy, no type listed (EFI System Partition, came this way)
which we assume is your ESP partition.
At that time, you had a Windows bootloader in there. Now you also have a GRUB2 boot loader in the ESP to boot Kubuntu.

You can find out how much space is left in your ESP this way:
In Kubuntu, open Konsole (K > Application > System > Terminal/Konsole), and type
df -hT

I have just Kubuntu 14.04 on this PC, and mine says this about the ESP partition (sda1--500MiB):
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda1 vfat 500M 3.4M 496M 1% /boot/efi

Just 3.4 MiB used for the relevant GRUB2 files.
I'm thinking your Windows bootloader files could use 30 MB--guessing here.

-Latitude-E6430:~$ df -hT
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda4 ext4 12G 6.0G 5.2G 54% /
none tmpfs 4.0K 0 4.0K 0% /sys/fs/cgroup
udev devtmpfs 1.9G 4.0K 1.9G 1% /dev
tmpfs tmpfs 386M 1.5M 385M 1% /run
none tmpfs 5.0M 0 5.0M 0% /run/lock
none tmpfs 1.9G 148K 1.9G 1% /run/shm
none tmpfs 100M 20K 100M 1% /run/user
/dev/sda7 ext4 384G 67M 364G 1% /media/Data
/dev/sda5 ext4 5.8G 124M 5.4G 3% /home
/dev/sda2 vfat 100M 22M 79M 22% /boot/efi
//rt-n66u-8060/Storage cifs 917G 57G 814G 7% /media/LAN_Storage

Your guess of 30 MB was pretty close -- 22 MB if I read it correctly.

Yeah, looks like yours is 22 MiB, and that includes bootloader files for both Windows and Kubuntu.

You can see them, the files. By command line using list commands (ls), or simply using Dolphin.
The ESP partition is mounted on the directory /boot/efi as seen from your Kubuntu OS.
Inside that directory is the EFI sub-directory.
Inside that is an Ubuntu directory (for Kubuntu bootloader files) and another directory folder for Windows boot loader files. Anything with an extension .efi is an executable file (a program).

So, in Dolphin:
/boot/efi/EFI/ubuntu/
and
/boot/efi/EFI/<some_Windows_folder_I forgot_the_name_of/

Thanks for checking.
