Copying HP Factory Image to an ISO?
I recently picked up an okay-ish HP Pavilion desktop, one of those machines that, on their own, aren't too spectacular, but can be easily upgraded to something fairly decent. It came with a WD Blue 350GB HDD, which I intend to replace with a 64GB SSD and a 2TB HDD. The 350GB HDD still had the original factory installation of Windows 7 on it and even had the Factory Reset partition. While I intend to install Windows 8/10 on it and download the drivers for the parts on their own, I'd still like to have that factory image around for good luck or whatever.
I have a SATA-to-USB thing that I can use to plug the HDD into my laptop, and I can then view all the partitions of the drive, but I'm a bit apprehensive about what to do from here.
Do I just open a program to make ISO files and tell it to make an ISO from the factory partition? Would the factory image know if it had been put onto a flash drive and refuse to work? Would it require itself be on the main hard drive of the system?
