Having huge issues with an HP laptop - there is no sticker on it but I checked through command prompt and looks like it's an HP 15
It need some updates, but when I go to Windows Update, it says 'your device is missing important security and quality fixes' but when I click Check for Updates it spins for a couple of minutes and then just stops without bringing up any updates.
I backed up all the data, but when I try to do a Fresh Start or Reset of the computer I get: "There was a problem resetting your PC, no changes were made".
Ran a full system scan and it said that it found and repaired corrupt files, but that has not helped anything. 
Went to MS and created a USB media tool and tried that but could not boot from the USB.  Changed the boot sequence and turned off secure boot and enabled Legacy settings - still would not boot from the USB, but at one point was bringing up a screen with a bunch of colors sort of blinking.  Also downloaded the .iso image and used RUFUS to burn it to USB and that also would not boot.  Went into Recovery and from Advanced Startup tried to boot from USB and same issue.
I ran CCleaner and cleaned everything up in the registry but still same issue...I realize the OS is probably corrupted, but how can I reinstall Windows when it won't boot to my USB...there is no CD drive on this laptop.
Any suggestions/help would be GREATLY appreciated.
