    While booted into Kyhi's rescue drive, @Pentothal needs to do some drive cleanup using MiniTool Partition Wizard. The first "EFI System Partition" needs to be reduced in size to 100 MB. The 460 MB recovery partition needs to be moved to the end of the disk. The C: Windows partition then needs to be expanded at both ends to fill the empty space. After that is completed and then re-booted back into Kyhi's rescue drive, the newly resized 100 MB EFI System Partition needs to be deleted and a new one created and populated with a BCD with the bcdboot command. Any pending changes need to be reverted on the Windows installation using the dism command.

    If it boots. My daughter's laptop just went into a blue screen boot loop after a failed update. She would get the "Your PC ran into a problem" blue screen. Would not boot into safe mode or recovery environment either. I attempted to simply rebuild the ESP, with the same results. I finally had to remove the drive from her computer, connect it to my desktop. Used the dism command while booted into my desktop Windows to revert pending changes on her Windows install. Reboot my desktop into her hard drive, still connected to my computer, then upgraded it to 1909 from an ISO file. After that I moved it back into her laptop and all was well. That was the only way I could fix her series of different blue screen boot loops.

    Ok @NavyLCDR I-m doing the resizing now with minitool. Then I-ll reboot and delete the 100mb efi partition.
    To create a new one may I follow post #46 instructions?

    Thanks

    Not exactly. After all the resizing is done, you should end up with a 100MB partition first, followed by C: drive partition, followed by Recovery Partition. Use MiniTool Partition Wizard to delete the first small partition. Make sure to apply. You should then have 100MB unallocated space followed by your C: drive partition, followed by Recovery partition. When you get to that point, in a command prompt run:

    Code:
    diskpart
    list disk
    select disk 0  <-note, make sure 0 is the disk you want to create the ESP on.
    create part EFI
    format fs=fat32 label="ESP"
    assign letter=w
    exit
    bcdboot C:\Windows /s W: /f UEFI  <-note, you might need to change C:\
    dism /Image:C:\ /Cleanup-Image /RevertPendingAction <-note, you might need to change C:\
    exit

    Ok @NavyLCDR the resizing and deleting of the first partition is ongoing (it takes forever). ASAP I-ll boot to command prompt and do the typing...wish me luck

    Ooooops, wiped out now.

    - - - Updated - - -

    It looks like Minitool Partition Wizard is stuck......no disk activity at all and the percent is not progressing. Not the best thing to happen
