I have a brand new Dell Inspiron 5000 with Windows 10. I've shrunk the windows partition and tried to install an Ubuntu 16.04 LTS to have a dual boot.
The installation (sda8
for /
and sda9
for /home
) runs well until it tries to install grub
. At this point it fails with a "critical error
" and I'm not able to boot Ubuntu.
Trying to repair grub with boot-repair I have the same error.
I've tried installing Ubuntu 14.04 LTS with the same result.
Investigating a little I've seen that if I try to mount sda1
, this partition is always read only. Is this normal? Any idea on how can I complete my dual boot?
This is the paste bin from boot-repair:
By the way, I've turned off the fast boot in Windows 10.
sudo dosfsck -t -a -w /dev/sda1
from Ubuntu. In a few cases has to mount read only ro, back up everything, remove partition, recreate partition as FAT32, with boot flag to make it an ESP and restore data. Back up of ESP is always a good idea as that often is not included in most backups.
