Hello, I’ve done a lot of bootable usb thumbdrive / pen drive in my line of work. I’ve bootable Ubuntu on one of my usb drive, bootable windows 7, bootable Windows 10 installer, Linux based recovery software to fix windows hard drive etc.
As long as you’re able to plug in your usb and give me access to your laptop, I’m able to assist to help u make a bootable usb with memtest inside.
Depending on your download speed, it will take 15 min - 1 hour max. Make sure you have a empty usb stick as it needs to be formatted.
Chat me up for more details!
