edit boot options and add line "init=/bin/bash". Boot will log into a root account directly. Just like that ?!

I see that physical access means everything but you at least need a livecd to hack windows password. AFAIK


any ideas about that?

First thing, you're doing this from your own computer. Are you also allowing unrestricted remote logins?
Are you foolishly running sudo and allowing your user passwords to be openly stored?

This move of yours ranks up there with .

Addressing this is simply a matter of configuring your bootloader's security options according to your needs.

And yes, physical access means Game Over on any OS.

BTW, I've changed the thread title to something less sensationalistic.

Set password in GRUB and be happy %) .

But you can't edit boot options; unless you are permitted. It is a general practice, that you protect your GRUB with password.

Yes, on a system that has been unsecurly setup it is that easy. Just as a side note, things can be done to Windows too to make it as vonerable when one has "phisical" access to your computer. As already suggested, set a boot password in GRUB or LILO (or whatever bootloader you want to use). You can make things more secure from the average Joe Cracker by setting a BIOS password and disable booting from "other" devices. You will need to find some means of securing/locking your computer case as well. Using encripted file systems is also benificial. However, (as already pointed out) once a cracker has phisical access to your computer the game IS over. These things just slow them down a little. It doesn't matter what OS you are using the end result is the same... phisical access = access to everything.

thanks for answers
