Ok, I renamed the UUIDs to the right "dev/sda´s", like so: Qud8pXy.jpg and o3sIxmR.jpg

then I tried to "ybin", but it fails (as always): 5XwCERo.jpg a bit strange, seems like "sda2" is missing all the time I try to run ybin, but it´s there...

guess it´s fucked up!

Here is my idea: would it work, if I just copy my sda3 data to USB Stick, re-install linux and then just copy data from usb to harddisk?

The problem is (like I posted in the beginning of this thread), that I do not want to setup all stuff again in debian...

Is there a way to boot from ubuntu cd, somehow make a copy of all data from my ext4 linux partition and later write back onto a new install?
