[Bug 1529010] [NEW] Excuting 'grub-install /dev/nvme' failed

[renlei]

Public bug reported:

Hi all,
Recently I use nvme ssd install ubuntu os (ubuntu_14.04.3_desktop_i386.iso) at sony latop met a very strange phenomenon.
sony VAIO bios ver: R1041V7, legacy mode.
I use two way install os.
first way:
 record the ubuntu image to DVD, use usb cd-rom install the os on nvme ssd, can install success and boot success.
second way:
record the ubuntu image to USB, use USB install the os on nvme ssd, met "Executing 'grub-install /dev/nvme' failed" issue.

from the install log, I find the first way, can install grub success on
/dev/nvme0n1, but use the second way, grub-install will install to
/dev/nvme, so it will failed.

why will appear this phenomenon?
