    1) What problems were you having that you performed a reset?
    a) was it a reset save files or a reset remove files?
    2) Are your files backed up?
    3) Had you made a backup image?
    4) If you needed to would you be able to perform a clean install (delete partitions, format, make an unallocated drive, reinstall windows 10 version 1703)
    5) Do you know the status of the windows drive?
    a) had you had any chkdsk problems or known drive problems?
    b) had you run any HD tests such as SMART, short, or long generic?
    6) Are you using HD or SSD?

    Perform the following steps:
    1) Find 3 flash drives that you can format

    2) With the first flash drive create a bootable windows 10 iso
    Download Windows 10
    Download Windows 10

    3) With the second flash drive create a bootable Memtest86+ version 5.01 drive

    4) With the third flash drive create a bootable Kyhi drive:

    With step #2 you can reinstall windows 10 version 1703.

    Each computer manufacture has F keys to boot a device or boot to the bios.
    Once you have created the bootable Windows 10 iso insert it into any USB port.

    If you repetitively click the applicable Lenovo F key you should be able to boot to the external hard drive or bootable windows 10 iso.

    List of PC brands with their corresponding hot-keys

    If you have any difficulty booting you can
    1) switch USB3 to USB2
    2) use another flash drive to create a bootable windows 10 iso
    3) boot to the bios and change the bios boot order

    Once you have booted to the windows 10 iso you can follow this link with text and images on clean install:

    With the clean install perform windows updates without installing other applications.
    Then various tests can be performed on the computer environment without the other applications.

    Is there a way to get into safe mode ?
    Note- FYI: only if you can at least boot to a login screen. You can't do that from a boot disk e.g.

    See if you can use the GPT method:

    To manually wipe a drive and convert it to GPT:

    • Turn off the PC, and put in the Windows installation DVD or USB key.
    • Boot the PC to the DVD or USB key in UEFI mode. For more info, see Boot to UEFI Mode or Legacy BIOS mode.
    • From inside Windows Setup, press Shift+F10 to open a command prompt window.
    • Open the diskpart tool:
    • Identify the drive to reformat:
      list disk
    • Select the drive, and reformat it:
      select disk <disk number>
      convert gpt
    • Close the command prompt window.
    • Continue the Windows Setup installation.
      When choosing an installation type, select Custom. The drive will appear as a single area of unallocated space.
      Select the unallocated space and click Next. Windows begins the installation.
