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

[YannUbuntu]

@Eric: thanks for your feedback.  I attach your Boot-Info in text file just in case the pastebin expires. 
Your Read-Only error is:
cp: cannot create regular file '/boot/efi/EFI/ubuntu/grubx64.efi': Read-only file system
(eg line 1979)

@Phillip: 
his dosfsck is from line 1262
his dmesg is from line 1993
his syslog is from line 3510
Hope this helps.

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

Status in “grub2” package in Ubuntu:
  Confirmed

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.

  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).
