Problem console recovery mode

Post by inanox » Sat May 12, 2018 10:20 pm

Hello,
I had a problem, modifying a line / etc / fstab I made a mistake and now my linux does not start. I try to modify it using the recovery mode but I only have access as read, not write.
I would like to know if there is any way to modify that line of code with write permissions from the grub recovery mode.

Also, I want to know if is possible save in another device the data of my sdd disk.

please help

I would think starting the editor with sudo would do it. If not, you can do it from your install DVD or USB stick.

Can't imagine why not.

In the recovery mode, drop to the root prompt and run

Code: Select all

mount -o remount,rw /
... and if you want edit /etc/fstab, it goes

Code: Select all

nano /etc/fstab
... saving and quitting
Ctrl o
Ctrl x
... and in the end sync files

Code: Select all

sync
reboot

"... any way to modify that line of code with write permissions from the grub recovery mode..." No, you have to load a Linux and a GNU because GRUB recovery mode does not have the commands you need.
