How to get rid of read-only mode?

Question

linux

I bought myself a Raspberry Pi kit, which includes, among other things, a flash drive with Raspbian preinstalled. I connected Malinka via a serial port to a PC, got on the Internet for accompanying information. And then I came across a problem: all operations with Malinka come across a message that the file system is in "read-only" mode. Can anyone explain to a person familiar with Linux solely from the Wikipedia article how to bring the file system into a "writable" state?

Answer 1

In general, the problem turned out to be in the system pre-recorded by Chinese friends and was solved by reinstallation. Thanks to all.

Answer 2

a person familiar with Linux only from Wikipedia will find it difficult to understand any answer on this issue. from the simplest that one can suggest issuing the command as root (superuser) mount / -o remount rw . this command will put the root system in read\write mode
