Do the following (for beginners):

I assume you already have a flash usb with ubuntu .iso

1. Boot your usb on try ubuntu

2. Ubuntu Software > install Gparted

3. Open gparted, right click on you desired partition to install Ubuntu > new > New Size : 200 MiB; filw system: fat32; > Add ; Something like this should be done:

4. Right click on EFI partition just created, Manage flags > boot

5. Apply changes on gparted then exit gparted

6. Install Ubuntu, when appears where to install choose something else>

7. double click on efi partition, choose EFI

8. Double click on desired partition to install ubuntu, choose ext4, mount point "/"

9. Install

Do the following:

1. Create FAT32 partition with 200Mib with "boot" flag
2. Run installation
3. Choose partition to install ubuntu...
4. Choose FAT32 partition as EFI partition
5. Choose your swap partition if you want
6. Install
