I was trying to update Ubuntu 12.04 to a new version and the computer crashed during the process. This is a computer with Ubuntu and Windows 7 installations.
After power button reboot and after selecting Ubuntu from the GRUB menu, the system provides a shell interface simply saying
Filesystem check or mount failed. It also suggests to hit CTRL+D to continue booting, but after that it says
mountall start/starting and then the same initial error.
I do not understand the mechanics of system recovery and searched this site for some info, and got to this question, where there is a nice explanation of potential recovery steps:
However, since I don't understand how the system works, I am a bit worried that taking this steps might affect the Windows installation I have alongside the Ubuntu one. I do not understand the basic concept of "mount" commands, hence my question.
When I run
df -h in the recovery shell, this shows up:
Filesystem Size (...) Mounted on udev 3.9G /dev tmpfs 1.6G /run /dev/sda6 92G /
I suppose the
/dev/sda6 only corresponds to a disk partition where Ubuntu is installed.
Is there a possibility that these recovery steps might affect the windows installation/files? Apologies for the noob question, but I really lack understanding of these issues.
