I just tried mount -o remount,rw /dev/sda1. It says "mount: /run/miso/bootmnt: cannot remount /dev/sda1 read-write, is write protected".
The usb is created by using UsbWriter under Windows and write the manjaro-kde-18.1.2-191028-linux53.iso to the usb. It seems the above method does not work. How to modify its boot parameters? 2019年10月31日 15:21 来自 [email protected]: > Hi, > > Afaik, you should be able to mount the live-boot usb as read/write after > boot, and then modify > boot parameters from `/etc/boot/grub` > ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ > On Thursday, October 31, 2019 8:58 AM, Dalao <[email protected]> wrote: > > >> Hi, I was using Seabios but recently switched to Tianocore.
