bug#44027: 1.2-29a2eb3 Installer fails at final stage installing GRUB.

[Brendan Tildesley]

|Going through the GUI installer selecting all the defaults, and install 
with LVM and ecryption, AND for the normal option without encryption I 
get these errors on TWO different laptops, both ~10 years old with BIOS. 
Encrypted: Installing for i386-pc platform. grub-install: warning: this 
GPT partition label contains no BIOS Boot Partition; embedding won't be 
possible. grub-install: error: embedding is not possible, but this is 
required for RAID and LVM install. Unencrypted: ||Installing for i386-pc platform. grub-install: warning: this GPT 
partition label contains no BIOS Boot Partition; embedding won't be 
possible. grub-install: warning: Embedding is not possible. GRUB can 
only be installed in this setup by using blocklists. However, blocklists 
are UNRELIABLE and their use is discouraged.. grub-install: error: will 
not proceed with blocklists.|
