I have an HP TM2T that I've grown to love over the last few years and this morning, the HDD died. I figured this is a perfect opportunity to switch over to a SSD (I was thinking the 256gb Crucial M4 or Samsung S3, whichever is cheaper). I have a handful of questions though.
I have the original key that came with my laptop but I don't have and Windows installation disks. Can I burn those from another machine and use them with my key? I don't want to pay for windows again.
My laptop doesn't have an optical drive, if I buy an external USB optical drive, can I use that to install Windows? Is there a better option?
As DarkOutlaw said, you're good to go - the OS key is the important bit. Chances are the SSD should be fine. For future, and as a good idea, try to get an imaging backup software (e.g. Acronis or Ghost) - they make a huge/massive/etc difference when reinstalling your OS partition/drive.
