grub-efi cannot install on locked ESP (read-only error)
Some Windows8 computers come with a locked ESP that prevents writing outside the /EFI/Boot and /EFI/Microsoft folders, thus preventing the creation of a /EFI/ubuntu folder.
This leads to a "Read-only" error when trying to install grub-efi.
Remark: this is similar but not duplicate of Bug #1090829
1) via Gparted create another EFI partition (FAT32, 200MB, located in the first 100GB of the disk)
2) move the 'boot' flag on it
3) make Ubuntu use this new ESP (eg via Boot-Repair --> Recommended Repair).
