I had Ubuntu and time ago I installed Linux Mint.
During installation there was no option for alongside install, so I chose the manual option for the install to empty the partition (mount point /).
After installation was completed now I can launch only the new LinuxMint. But how can I load the old Ubuntu? I tried to load it from Linux Mint Grub2 console, but then, after
set root=(hd0,msdos6) linux /%vmlinuz% initrd /%initrd% boot
Computer loading just into BusyBox and can not proceed loading (Ctrl+D) because of
/root/dev/console not found error.
switch_root -c /dev/console / /init is not working (outputs help message) and
exec switch_root also does'not work.
So, what did I do wrong?
