I installed iAtkos V7 (Leopard) on my Laptop

Acer Aspire 5810TZ
Intel Pentium 1.3Ghz 800Mhz FSB
Intel GMA 4500M
4GB DDR3 Memory

I am multi booting with several partitions.
1 Mac OSX Leopard
2 Windows 7 Home Premium
3 Ubuntu Root
4 Ubuntu Home

I installed Ubuntu last, so I am running the GRUB bootloader. I want to install Chameleon, and that's where I run into problems.

When I am installing it, it asks for my Administrator Password. Well, I enter my username and password, but it doesn't accept it. I try several variations, to no avail. I look up the user accounts, and it shows my user account in there, and the password is correct. After some studying, I realized that my user account is only a standard account, and not an administrator account. There is no administrator account listed. When I click on the lock to unlock the account, it wants me to enter an administrator's username and password. My account is the only account I put on here.

I have reinstalled Mac a few times since the original install, using the same username and password combination.

I don't want to have to reinstall anything else again. I have installed Mac Windows and Ubuntu several times, in the last week. I especially don't want to install Windows again, because I don't want my Activation Key to run out, since it's legit, and is being registered 5 times a day everytime I crash my computer.
