My brother is a tech guy for a local computer shop, and over the last few weeks we have been having this little competition... I know it's all fun and games but it really is improving my knowledge of PCs. My question is what to do next- so far:
I had no password, so he was able to just log on.
I password protected my administrator account, and he got onto a hidden administrator account through safemode.
I searched around here and found out how to disable the hidden administrator account.
He then booted onto the PC with a Live Cd of Linux? Somehow he turned off my password.
Then set a BIOS password and disabled boot from the optical drive without the password, but then he booted from a USB stick.
So then I locked all bootable devices without the password, but he took out the CMOS battery from the motherboard and it erased the BIOS settings...
What's next? Is it even possible to securely lock your PC? What about hard drives... how do I secure those so that if they are removed from the system and booted as a slave drive they wouldn't be accessible? I posted this in the geek talk section because my system is in no real trouble, as it's all just my brother. Thanks for any replies
