I got Puppy Linux on a CD and am booted on it currently. Do I have to install a special program for it to wipe my HDD (I want to install Windows 7 on it afterwards) and if so can somebody give me a step by step on how to? Don't really know how to work this OS.
if you're on puppy linux, then right click on the desktop -> system -> gparted partition manager.
after gparted starts select all devices (scan all drives) from the message window click ok.
you'll see your drive(s) under the main toolbar with total capacity preceded by /dev/sda (if you have only the hdd connected).
right click it or select your preferred actions from the menu bar e.g. partition - you can delete, resize partitions, format the disk etc.
since you want to run windows later on, delete the existing partition table and format it a few times (you will have to click on the Apply button for the action to take effect). format it to ntfs filesystem.
take out the puppy cd, insert the windows 7 installer disk, reboot, follow the instructions, format the disk to ntfs, follow more instructions, install.
if you want windows 7 info search thg forumshttp://www.tomshardware.com/forum/forum-63.html
and/or go to microsoft's website, select windows 7 and look for how-to guides.
i hope this helps you a bit.
