Hi, I decided to try out what I am hearing as an awesome OS to come! But I am trying to install it on my older windows 7 home prem HP G71, I meet all the qualifying specs, and a little more. First I downloaded the ISO from my windows 8.1 (the main laptop I have) and burned it to dvd.. On the win 7 machine I of course made a system image recovery set and repair dvd set (thank goodness for that). I began to install it from boot and all seemed to go well except it referred often to returning to win 8.. when the installation failed from the ISO DVD, I used the win 7 recovery discs and had my system back up and running again.. SO I began to think maybe it needs to be downloaded to the system it is going to run on, or same OS at least.. SO I came back and downloaded the direct install file that goes through the windows update, and I worked fine, at least I thought it did.. After it installed all components and finally came to the windows log in screen I moved the mouse pointer to the password box and before the pointer could get there it froze and I got a DPC_WATCHDOG_VIOLATION error blue screen.. And it rebooted, it did this several times until I just gave up, then I tried using just the arrow keys I got passed the log in password and was prompted for internet connection, although it was already connected to my wifi, I needed to click next on that page to proceed, however it was very laggy and I tried to use the keys to scroll down to where I could move to the right to click on next, and it seemed to freeze and I touched the mouse it moved a few inches and the blue screen same error again.. Now I feel I need to say, I purchased this laptop over 5 years ago through a discount chain, but never had an issue before. I reformatted a few times as I tested different games on it that never worked for that computer anyway, but the clean installs went great, except the one I did a few days ago before I was ready to try win 10 on it.. After a factory recovery I found at the bottom right the not genuine windows message. Well when I was prompted that it was not genuine, I only have to skip registering (I usually do on re installs) and get to the desktop where I was able to go into the properties of my computer and added product key to the one on the sticker of the computer and all was well.. I say that because I wonder is that maybe what my issue is here? And how can I fix this issue? Thanks for any help!!
