How to bootup Vista setup

Hi, my pc is on nothing. How can I boot up Vista setup. I'm doing it through usb

Are you saying you want to install Vista?
Do you have a install DVD or flash drive?
If not, post post here:

Vista ISO download

and ask Peter (Ex_Brit) to send you the link to the versions of Vista you need, 32 or 64. Include your E-mail address mucked up, like abc at xyz DOT com then edit your post and remove it as soon as you receive the link.

The ISO Peter provides has both SP1 and SP2 applied.

During the install, when asked for the key, don't enter it. You will then be given a menu where you can chose the version you want to install.

Activate once the install is completed.
