[Bug 1091477] Re: grub-efi cannot install on locked ESP (read-only error)

[YannUbuntu]

Phillip, here is what you asked:

http://paste.ubuntu.com/1562554/
Line 1088 shows the bug.
Then lines 1111 and 1112 show a fsck on the ESP with no error.
Then line 1113 shows the bug is still here.

Title:
  grub-efi cannot install on locked ESP (read-only error)

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  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.

  Example:

  Remark: this is similar but not duplicate of Bug #1090829

  **************** WORKAROUND:
  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).
