As I said in another post I have Slacko 5.7 nopae version installed on USB.
The method I used to install Slacko was the puppy universal installer. Since it take awhile to reboot about 5 minutes or more. I left & did other things. When I came back, Windows 7 64 bit reported a messed up boot loader. The odd things is, the flash drive is not set as the default boot loader in the bios. I press F12 at boot up and manually select the flash drive. I usually pull out the flash, the moment the computer boots up.
