    Hi Dharmendra Dharmendra

    I’m sorry you’re dealing with such a frustrating loop during the Insider Preview 26220.7752 update. The screenshots you shared make it clear the system is failing to boot because the update damaged the bootloader, which is why you’re constantly redirected to Troubleshoot instead of completing the installation.

    Here's a few thing you can try to resolve the winload.efi 0xc0000098 error:

    1)Rebuild the Bootloader (Most reliable) This can be done directly from Advanced Startup Options.

    • Open Troubleshoot
    • Open Advanced Options
    • Select Command Prompt
    • Run the following commands one by one:
    bootrec /fixmbr
    bootrec /fixboot
    bootrec /scanos
    bootrec /rebuildbcd
    

    Restart the system afterward.

    If you get “Access is denied” on /fixboot, let me know and I’ll provide the workaround.

    2)Repair the EFI Partition Manually If the BCD rebuild doesn’t help, repairing the EFI folder can restore winload.efi.

    • In Command Prompt, run:
    diskpart
    list disk
    select disk 0
    list vol
    

    Identify the EFI partition (usually FAT32, about 100-300 MB).

    Then enter:

    select volume <EFI-volume-number>
    assign letter=Z:
    exit
    cd /d Z:\EFI\Microsoft\Boot\
    bootrec /fixboot
    bcdboot C:\Windows /l en-us /s Z: /f ALL
    

    Restart the PC.

    3)Uninstall the Failed Insider Feature Update

    Since the issue began right after installing 26220.7752, rolling it back may restore boot without additional repair.

    • Go to Troubleshoot
    • Go to Advanced Options
    • Select Uninstall Updates
    • Choose Uninstall latest feature update

    4)Use USB Installation Media for Repair

    If the above options don’t resolve it, performing a startup repair or command‑line repair from bootable media tends to work.

    This keeps your files and apps intact as long as you choose Repair your computer instead of Install.

    5)Restore from a System Restore Point

    If you have restore points enabled:

    • Go to Troubleshoot
    • Go to Advanced Options
    • Select System Restore

    Choose a point before the update attempt.

    Hope these can help. Feel free to update here if anything comes up!
