/dev/sda8: clean 271789/1222992 files, 1952109/4882432 blocks
[ 10.015870] tom_crb msft0101:00: can't request region resource [mem 0xfed40080-0xfed40fff]

there multiple problems need answered question.
the first , foremost problem /etc/fstab. it's been radically changed standard, , windows partition trying mounted @ 2 different mount points @ same time. caused computer not boot, , halt in emergency mode. here comment out both windows disk mounts, , got computer boot.
in /etc/fstab:
change this:
# /windows on /dev/sda3 during installation uuid=5cce72f7ce72c8b2 /windows ntfs defaults,umask=007,gid=46 0 0 # swap on /dev/sda7 during installation uuid=c35ada9f-7d1a-4220-8c12-5f69cad3236e none swap sw 0 0 uuid=5cce72f7ce72c8b2 /media/data ntfs-3g defaults,windows_names,locale=it_it.utf-8 0 0 uuid=2605-3dc2 /boot/efi vfat defaults 0 1
to (just comment out 2 lines):
# /windows on /dev/sda3 during installation # uuid=5cce72f7ce72c8b2 /windows ntfs defaults,umask=007,gid=46 0 0 # swap on /dev/sda7 during installation uuid=c35ada9f-7d1a-4220-8c12-5f69cad3236e none swap sw 0 0 # uuid=5cce72f7ce72c8b2 /media/data ntfs-3g defaults,windows_names,locale=it_it.utf-8 0 0 uuid=2605-3dc2 /boot/efi vfat defaults 0 1
then reboot. success!
then, clean rest of messy fstab, following edits.
change this:
# /boot/efi on /dev/sda1 during installation #uuid=2605-3dc2 /boot/efi vfat umask=0077 0 1
to this:
# /boot/efi on /dev/sda1 during installation uuid=2605-3dc2 /boot/efi vfat defaults 0 1
then delete last line of fstab looks like:
uuid=2605-3dc2 /boot/efi vfat defaults 0 1 lastly, change this:
# /windows on /dev/sda3 during installation # uuid=5cce72f7ce72c8b2 /windows ntfs defaults,umask=007,gid=46 0 0 # swap on /dev/sda7 during installation uuid=c35ada9f-7d1a-4220-8c12-5f69cad3236e none swap sw 0 0 # uuid=5cce72f7ce72c8b2 /media/data ntfs-3g defaults,windows_names,locale=it_it.utf-8 0 0
to this:
# /windows on /dev/sda3 during installation # can't have 2 mounts, 2 different mount points, @ same time. # both of these mounts wrong. # uuid=5cce72f7ce72c8b2 /windows ntfs defaults,umask=007,gid=46 0 0 # uuid=5cce72f7ce72c8b2 /media/data ntfs-3g defaults,windows_names,locale=it_it.utf-8 0 0 # if must mount windows partition, i'd recommend this... # uuid=5cce72f7ce72c8b2 /media/data ntfs-3g defaults 0 0 # swap on /dev/sda7 during installation uuid=c35ada9f-7d1a-4220-8c12-5f69cad3236e none swap sw 0 0
then, in windows, these:
if dual-boot windows , ubuntu, must turn off fast start , hibernation in windows.
- turn off
fast startin power control panel
in power control panel, click on change power button does
then choose change options unavailable
uncheck fast start
- in administrative command prompt window, type
powercfg /h off
