I bought a new SSD to install it in my HTPC. Before, I had an HDD with Kubuntu. I would need to copy the files from the / partition from HDD to SSD. To do this, I booted from the Kubuntu livecd, mounted both disks and copied all the files over:
sudo cp -ax /media/hd /media/ssd
Following this answer: How to move Ubuntu to an SSD, I´m stuck with this step:
Then you just need to edit the /etc/fstab on the ssd to point to the new fs UUID ( you can look it up with blkid ).
I don´t know how to do it because if I try to edit the /etc/fstab on the SSD, it gives me an error telling me that there is no such a file or directory. I try this approach:
sudo nano /media/ssd/etc/fstab
because I mounted the ssd on /media/ssd in order to copy the / partition.
