Lost windows vista password

Hello,

ive recently received a Satellite M305-S4848 Toshiba Laptop with Windows Vista,
i made a password for the log in, and stupidly forgotten the password..
ive looked at many websites, most of them say that i need to create a password reset disk in order to do so but the only way is to have made it before i lost the password so that doesnt really help me too much.
then i came across another website that told me how to create a disk to boot the computer..
im not very good with computers so i was a little confused but i was being very careful and went through a step by step guide on how to create the disk.. [ basicly burn an .iso image file and restart the computer or whatever]
it said that it should have automatically booted when i restarted the computer but it didnt, so i made sure that the cd/dvd drive was 1st on the boot menu thing, and it was..
but still did not work..

does anybody know another way on how to get my password back? =/
or maybe at least even wipe out the password fully so i can just get onto my computer..?

this would be greatly appreciated!
thank youuu!
