From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hey guys. I'm new to Linux and I'm running Linux Mint 21.2 Cinnamon. Yesterday I have f*cked up. I was testing things in users and geve myself standart priveledges insted of Admin ones I had from beggining and then restarted PC. I then tried log back into users tab and change myself back to Admin but even tho the password is correct It says that it is not. /So at this point there is only one user in PC who has standart privliedges and no Admin./ I then tried to access root via terminal and this time It said that I don't have permision to do that. And this is where I'm at right now. Please help get back my admin privliedges.

Edit: Issue is fixed. I started GRUB and changed my password which fixed the whole issue. Once again big Thank you to everyone who gave me tips and also big thank you to the guy who started posting about rowing machines. You all wonderful.

Yes, there are other ways of doing it as well, you can plug in a live iso and chroot into your proper root and change it for example. This is why you can put a password on GRUB and on your BIOS, even if both of them have passwords, someone can remove your disk plug it into another machine and access your data. Long story short if someone has physical access to your machine is essentially game over. And BTW this is also true for Windows, physical access to the machine has always been considered game over because the person can simply remove the disk and plug it in another system, so any software solution is useless.

This is why encryption is important, if your disk is encrypted putting it in another machine gives garbage unless you know the encryption key, making root rw (as in the link) is useless because you still need to decrypt the disk to access it, plugging a live iso is pointless because unless you know the encryption key you won't be able to chroot into the system. But for most people the fact that no one untrustworthy will ever be physically near your computer is enough to not warrant extra measures of security, not to mention that most people don't have data that could be problematic if leaked (e.g. source code for a large company) and those who do have their drives fully encrypted.

Not exactly true on Windows. BitLocker is enabled by default when signing in with an MS account, which is what I’ve done for nearly a decade and I think is the cause of my confusion. I’m just use to encryption being enabled by default and not having to think about it.

I have NEVER seen personal windows with encryption, I have dual booted and retrieved data from windows computers for everyone else since forever and have never ever seen an encrypted drive. I'm sure some people do encrypt theirs but it's definitely not on by default, same as on Linux where it's one click during the installation that most people don't click.

It’s enabled by default when you login to windows with a Microsoft account, which they very rudely push on you and make it very difficult to login with a regular local account.

Not as far as I know. I've logged in with MS accounts on Windows and still been able to read the disks. Ok Windows 10 and above last one I used was 8.
