x acidreign x,

permissions will work because , If you read properly,

both have winXP pro and the boot sequence is setup that it boots my HDD if it is present and then his if its not.



both of them have a separate boot, therefore 2 administrator account.If Trust_Not_123, changes the file access his drive, grandfather wont be access his drive at all.

It doesnt matter who's boot is master of slave.

Trust_Not_123,

all you need to do is convert your file system to NTFS if it is FAT32 .
Then follow my instructions,


Log on using your administrator account
right click on your c drive

Go to properties
Click on security tab
Click add,
Click and choose your username
Then
Remove Everyone, (except your own account)

Now when your grandfather logs on using his account, he wont be able access your drive.


Trust me Trust_Not_123
