If you really want to know take a look at this link and you can test drive Linux Mint on your computer.Hi there,
Is HP Pavilion 15-cc115tu compatible to use linux mint?
Hmm the model you just mentioned isn't bad at all .Do you have the I5 model? Or i version which is the dual Core? Either way Linux mint will be able to run on both laptops( hardware) and you shouldnt feel any lag after the installation is done .
With that said , assuming you aren't that fimiliar with Linux in general I would suggest you use a software called UsbInstaller(mentioned above) .It's a simple tool to create bootable drives .The above post mentions Bootin tool as well and it works(almost) exactly the same but I notice a slight diffierence between both the tools when I use them so you can test both and see which you like .
1) Create bootable USB OR Burn to a disc
2) Boot to flash or Disk
3) Install from media .If you have an internet connection all the better .
Don't forget to update/upgrade your machine (Sudo Apt-get update , then apt-get upgrade) .
Sorry for my English and also for the late response .I'm pretty new here
