Q:

Initramfs revisited (Error in Ubuntu 17.04)

My problem is different to others I have seen at the forum. 
When booting the system this is what appears:
[1.168307] ACPI Error: [DSSP] Namespace lookup failure, AE_NOT_FOUND (20160930/psargs-359)
[1.1684911 ACPI Error: Method parse/execution failed [\_SB.PCIO.SATO.SPT2_ GTF] (Node ffff8914550e1938),AE_NOT_FOUND(20160930/psparse-543)

BusyBox v1.22.1 (Ubuntu 1:1.22.0-19ubuntu2) built-in shell (ash) Enter 'help' for a list of built-in commands.

(initramfs) 

Then, I write 'exit' and this is what happens:
mount: mounting /sys on /root/sys failed: No such file or directory 

mount: mounting /proc on /root/proc failed: No such file or directory

 /init: line 343: can't open /root/dev/console: no such file

This is the second time I install Kubuntu 17.04 in a week, and the second time that it happens. I have Windows10 installed as well, but it works fine. ¿Any suggest?
Thank you, very much.

From the comments...
It looks like the BIOS update may have solved some evils, but the boot problem still exists. With the ACPI errors gone, we may have you reinstall the OS one more time, but first let's check your existing file system.
To check the file system on your Ubuntu partition...

boot to the GRUB menu
choose Advanced Options
choose Recovery mode
choose Root access
at the # prompt, type sudo fsck -f /
repeat the fsck command if there were errors
type reboot

If for some reason you can't do the above...

boot to a Ubuntu Live DVD/USB
start gparted and determine which /dev/sdaX is your Ubuntu EXT4 partition
quit gparted
open a terminal window
type sudo fsck -f /dev/sdaX # replacing X with the number you found earlier
repeat the fsck command if there were errors
type reboot

Update #1:
To further check the hard disk hardware...
Use the Disks app to review the SMART Data & Tests data and run the tests. You could install gsmartcontrol to monitor the disk. Since this is a HDD, you could badblock the drive with e2fsck -c -k /dev/sdb while running  from a Ubuntu Live DVD/USB.
