[Bug 1509059] [NEW] NTFS EFI System Partition causes failure to mount /boot partition

[TJ]

Public bug reported:

A user with a Packard Bell EasyNote TE found that the installer failed
(hung with no apparent activity) after the partitioning step.

/var/log/syslog reports:

wrong fs type, bad optio, bad superblock on /dev/sda1

/var/log/kern.log reports:

FAT-fs (sda1) can't find valid fat system

The system came with a Windows installation. The user booted the Ubuntu
installer from USB, erased the Windows partitions, and told the
installer to use the entire disk for Ubuntu. The partitioning reported
failure to mount boot partition. The user rebooted and tried again. The
same happened.

>From a terminal we found the EFI SP was NTFS not FAT:

$ sudo blkid /dev/sda1
Label="recovery" UUID="XXXXXXXXXX" TYPE="ntfs" PARTBALE="EFI System PArtition" PARTUUID="XXXXXXXXX"

We worked around the issue with:

$ sudo mkfs.vfat /dev/sda1


However, if this were required to be a multiboot system it sounds as if the installer would be broken by there being an unexpected NTFS EFI System Partition.
