Then... my folder in my desktop with some important files suddenly dissapeared. Can I get that back?
After that, I went to the other account and it seems like that account did not have access to my folders. When I clicked my drive and my folders it said "access denied." I went back to my account and found that the accounts (users, everyone, system, etc) I deleted were put back on the permissions list. I just left those users there, but I checked/unchecked the "deny" or "allow" boxes where appropriate e.g. I clicked allowed for "adminstrator" and "owner" and clicked denied for "everyone" but then my computer froze. I think it froze while I clicked the check box to allow "system."
The window said it was not responding so I ctrl+alt+Del out of there and after that I can't boot into this drive at all. When I start Windows XP it goes to the Windows XP loading screen but never makes it to the log-on screen. It always restarts before the log-on screen appears. I tried starting on safe-mode but it also restarts. I tried repairing the OS with the Windows XP Pro CD at boot-up but it says that it can not install the files it's trying to install. Maybe this is because the account privileges isn't allowing this since I touched the account settings as I described above.
I hooked up this drive as a slave and booted the OS on my other drive. I can see my main folders when I look into the drive, but I can't click on any of them because it says "access denied."
How would I be able to fix this so that I can log on. Also, do you know why my folder suddenly dissapeared from my desktop? It just suddenly dissapeared, and I don't think it was in my recycle bin. Also, I am pretty sure that my computer was virus free as my antivirus is up-to-date.
Thank you in advance for your help.
