[Bug 2031977] [NEW] new dual boot install (win10 + Ubuntu 20LTS) crashes while installng grub

[Floris]

Public bug reported:

HDD with MBR
originally windows 10 PC, installing Ubuntu 20 on the side.
partitioned 500GB HDD with Gparted.
original partitions:
sda1: 500MB NTFS, boot, windows reserved
sda2: 336GB NTFS, Windows OS+data, (shrunk to 336 GB during partitioning)
sda3: 548MB NTFS, msftres

new partitions:
sda4: 152.21GB extended
sda5: 111.67GB NTFS, intended for windows data
sda6: 25GB ext4, intended for ubuntu OS. mount point "/target"
sda7: 15GB ext4, intended for /home
sda8: 550MiB fat32, intended for EFI. mount point "/target/boot/efi"

Since the install failed during GRUB install, at this point hoping my
windows will still boot....
