[xubuntu-users] unable to install grub

[Clarence Fender]

Yes, this is an install from a USB. If it's supposed to install GRUB by
itself, it's doing a very poor job :)   I have a 500M EFI partition. It
fails.

sda   - all primary partitions
1M (appears by itself, no format)
500M  EFI
50G  ext4  /
16M swap
remainder of space ext4 but not mounted

Thanks.
