Last Friday (June 16th 2017) I ran apt-get upgrade on a Linux Mint 18.1 machine and then rebooted the machine. To my big disbelieve the machine didn't come up anymore. After the grub2 menu, the following error appeared:
Loading Linux 4.4.0-53-generic ...
error: attempt to read or write outside of disk 'hd0'.
Loading initial ramdisk ...
error: you need to load the kernel first.
Press any key to continue...
Erm...Noooo! T_T
I booted into the Linux Mint 18.1 Live CD, mounted the drive /dev/sda1 as /mnt, bind mounted sys dev and proc and recreated the initramfs inside the chroot jail of the installed Linux Mint:
mount /dev/sda1 /mnt
mount --bind /sys /mnt/sys
mount --bind /proc /mnt/proc
mount --bind /dev /mnt/dev
chroot /mnt /bin/bash
mkinitramfs -o /boot/initrd.img-4.4.0-53-generic
update-grub
grub-install /dev/sda
exit
reboot
But I still got the same error after the reboot... I also manually selected the correct partition in grub in order to rule out a grub2 error:
grub> ls
(hd0) (hd0,msdos5) (hd0,msdos1)
grub> ls (md0,msdos5)
Partition hd0,msdos5: No known filesystem detected...
grub> ls (md0,msdos1)
Partition hd0,msdos1: Filesystem type ext* - last modification time 2017-06-19 05:44:26....
Partition start at 1024KiB - Total size 486333440KiB
grub> set root=(hd0,msdos1)
grub> set prefix=(hd0,msdos1)/boot/grub
grub> insmod normal
grub> normal
This got me back to the (updated) grub menu, but once I selected the entry for Linux Mint I got the same error again.
I booted again with the Live CD, this time with the goal to reinstall the Linux Kernel.
mount /dev/sda1 /mnt
mount --bind /sys /mnt/sys
mount --bind /proc /mnt/proc
mount --bind /dev /mnt/dev
chroot /mnt /bin/bash
apt-get install linux-image-generic
To my big surprise a new Linux Kernel 4.4.0-79 was installed. I expected apt to return "already installed" or something like this.
The installer returned some errors complaining about missing Linux headers but still finished the installation of the new linux-image package. I installed the header package afterwards:
apt-get install linux-headers-4.4.0-79-generic
The installation of the new Kernel packages created a new initramfs in /boot/initrd.img-4.4.0-79-generic and also a new/updated entry in /boot/grub/grub.cfg with the new available Kernel version.
I exited the chroot environment and rebooted the machine:
exit
reboot
And this time Linux Mint 18.1 was booting again.
Update July 4th 2017: I experienced an extremely laggy OS on this very same Linux mint machine so I checked the current status of the disk. And found this:
# smartctl /dev/sda -a

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
Yes, you see correctly: 899 sectors pending re-allocation and 277 sectors definitely defect. In the SMART self-test log there's even a read failure mentioned. Given the amount of hours this disk has lived so far (55700) this is not at all a surprise.
At least now I understand why apt-get upgrade resulted in such a broken OS before: The disk was already dying then.
