    Do you have both your stick drives with you?
    7-Zip has a portable version; not sure if this will work, but worth a try:
    7-Zip Portable | PortableApps.com - Portable software for USB, portable and cloud drives

    Put 7-Zip Portable on one stick drive. Use it to extract the ISO to your other stick drive, or perhaps you can extract the ISO to a folder on the W7 desktop and then copy those files to your stick?

    Oh - no WiZip, no 7-Zip either?
    I managed to mount the ISO file to the USB drive by using Rufus tool. But still couldn't get it boot under UEFI mode from external drive - "Operating System Not Found". When I changed to Legacy mode, machine picks up the USB drive. I have tried:
    1. Repair computer -> None of the options underneath could fix it.

    "Start-up Repair
    Start-up Repair couldn't repair your PC
    Press "Advanced options" to try other options to repair your PC or "Shut down" to turn off your PC.

    2. Reset the PC -> None of the options are working either.

    "Reset this PC
    Unable to reset your PC. A required drive partition is missing."

    3. Install -> Will report back later after a few attempts.

    @simrick : I truly deeply appreciate all your helps. God bless you having a great life and happiness.

    I could eventually get it to work last night. Here's how. The symptom was caused by the machine itself performing unfinished CHKDSK because of its internal interruption somehow and then following by my romantic long story with sugarless tear above for having Vaio as a long-term partner. I knew from the beginning that the Windows 10 ISO file was the only way out to solve this problem as I had no access to UEFI or any Windows tools/options to fix the laptop. After mounting the ISO to the USB, NONE of the menu options providing seemed to be working including an option to Install Windows was useless. By the way, UEFI is such a pain yet very secure. The Command Prompt was a true hero in this situation. In the beginning, it couldn't find my local C drive and then I tried using:

    X:\Resources\CHKDSK /f C:

    One magic line made a happy ending story, unbelievable. It started checking from the beginning with progress showing, finished all the process within less than 10 seconds. From my understanding clearing the old interrupted command and execute a new one, then the C drive was finally be found and things went back normal.

    I could perform everything I intended to do before that kaboom: create a recovery partition, creating the Windows 10 bootable USB drive in case the former one won't work, and check and repair all corrupted files. Now the machine is working faster than before with no sign of drive failure.

    That's great news @Bicentrium! Thanks for posting your solution - it may help others in the future. Cheers!
