Gentlemen, following your great replies on installing SSD , I completed the process successfully.
I left my old W7 installed on HDD and made new installation on SSD.
I can make a choice from BIOS what drive I want to boot and it works fine.
NOW, I have a problem how to use the new SSD.
The purpose of installing it was to make my X-Plane flight simulator run faster. BUT, I have two instances of it and they are both 80+ GB in size.
What it comes to , putting them on SSD will not give me much more room for programs I also need like Gimp, and few others.
What are the alternatives for using my new SSD? For cache? Any other way?
Thank you for your help and looking forward to your replies. Cheers, AJ
