И я столкнулся с таким же. С несколько иными симптомами, но на всяк
случай оставлю это здесь.
Без всяких raid, отдельного /boot тоже нет, корень на /dev/sda2..
297: grub2-pc #################################### [ 63%]
Updating grub on /dev/sda
/usr/sbin/grub-bios-setup: warning: Attempting to install GRUB to a
disk with multiple partition labels. This is not supported yet..
/usr/sbin/grub-bios-setup: warning: Embedding is not possible. GRUB

blocklists are UNRELIABLE and their use is discouraged..
/usr/sbin/grub-bios-setup: error: will not proceed with blocklists.
** WARNING: grub-autoupdate failed, NEXT BOOT WILL LIKELY FAIL NOW
** WARNING: please run it by hand, record the output offline,
** WARNING: make sure you have bootable rescue CD/flash media handy
** WARNING: and try `grub-install /dev/sdX' manually
Перезагружаться не рискнул.
Попытка сделать вручную grub-install не прошла:
# grub-install /dev/sda

Гугление навело на https://www.linux.org.ru/forum/general/7488486
Что в итоге и помогло (с некоторыми особенностями).
У меня было:
# grub-probe -d /dev/sda
ext2
Лечение - почистить несколько секторов за MBR (но до начала первого
раздела):
# dd if=/dev/zero of=/dev/sda bs=512 seek=1 count=3
После чего все благополучно установилось:
# grub-install /dev/sda
Installation finished. No error reported.
