I recently updated my Debian Linux (sid) and after a reboot It failed to start. So I used a Linux USB installer to start rescue mode to dig the problem and see what's going on.
First of all I could n't get access to the shell on my root file system (/dev/sda3) with ext4 file system which freaked me out that something serious is ahead so I Executed a shell in the installer environment to mount the root file system to figure out what is going on. So I did the following:
e2fsck -fp /dev/sda3 (to remove every possible error from my partition, no error on this command)
then I tried to:
mount -t ext4 /dev/sda3 /mnt/tmp and I get the following response: mount:
mounting /dev/sda3 on /mnt/tmp failed: no such device.
I already used parted /dev/sda 'print' to make sure I working on the right partition since it is the only ext4 I have.
Please help me if you know any workaround for this problem.
