    Cannot boot into Windows unless using USB containing Windows image


    Windows 10, ver. 1909

    tl;dr After removing Linux and installing Windows I can't boot without using the USB drive that contains the Windows installation image. Unknown filesystem grub rescue error.

    The whole story goes like this:
    I was running a Linux (Manjaro distro) system. I had to use W10 for work but couldn't configure a working virtual machine and decided to create a dual boot. I couldn't load the Windows system after that and even after troubleshooting it, nothing worked and only Linux loaded on boot. Didn't have any important data so I decided to completely re-install the system and use W10. However, this took a turn for the worse when I booted into the freshly installed OS. That is, didn't boot. I was greeted by this message:

    error: unknown filesystem.
    Entering rescue mode...
    grub rescue>


    I could only load USB image and try fixing it through CMD. Somehow managed to boot into the Windows setup menu and get the system running by executing some commands including bootrec.exe /fixboot (I don't know which one solved the issue). Right now, I can boot into Windows. However, on boot, I have to spam F11 to choose device to boot from and use the USB stick I have put into one of the ports. At least it works now, so I can manage short-term but anyone would agree this is not as functional as it can be.

    Does anyone have any idea how to fix this?
    Any help would be greatly appreciated, as this basically concerns my survival in this world. : D

    Looks like when you did the reinstall you did not delete the Linux Partitions and GRUB.
    Since you did a reinstall, it would be best if you started over and did a Clean Install.
    Boot off of the USB Flash Drive Windows Installer, choose your Language, then Custom Install. In Where to Install Windows delete ALL Partitions so the HDD/SDD is Unallocated Space, then press the Next button. Windows will create partitions and format them during the Windows install.
    If you still want to use Linux create a LIVE CD/USB or use Virtualbox to make a VM.

    With a Laptop like yours, you probably have a UEFI BIOS.
    Did you install Linux as UEFI- GPT or Legacy-MBR? Witch OS came with the laptop?
    It seems you have the boot loader on the USB and the OS on the internal drive.
    Once in Windows, open Disk Manager (C:\Windows\System32\diskmgmt.msc), expand the columns so we can read them and with the snipping tool take a snapshot of the whole window. Post it here as an attachment.
    I would like to see what you have on your internal drive and on the USB drive.

    Then remove or detach cables for disk management disks 1 and 2 then reboot and report findings into the thread.

    There is no trace of Linux partitions on your drives
    You don't need to reinstall. All you need is to set the boot loader (on the Fat32 - EFI partition) to point to the C: partition.
    I would first try a boot repair.
    - Shutdown
    - Detach the other disk (disk 2 on Mini tool)
    - Boot from the installation disk as UEFI, not legacy and do a boot repair.

    There is also some CMD commands (bootrec) but, as I'm not familiar. I won't suggest any.
    Probably someone else will do.

    @zbook Here are the results: New CMD output - Pastebin.com

    @Megahertz Thanks for the reply! Glad to hear I may not need another reinstall.

    I have some questions regarding your instructions:

    The FAT32 partition I can see is the USB drive. Is it the one you are referring to?
    How do you set the boot loader to point to a specific drive?

    I will give a try to boot repair. Last time it found an SrtTrail.txt error which I couldn't fix with bootrec commands because some of them could not be executed..

    What do you mean by "detach" in this case?

    On a UEFI-GPT drive, you have a small Fat32 partition with one or more boot loaders.
    If you look at the drive 1, the fist partition is the EFI Partition that needs to be repaired.

    By "Detach the other disk (disk 2 on Mini tool)" I mean to remove the SATA or power cable from the disk.
    You will attach it latter after a successful boot on disk 1.

    Oh, sorry about that, I didn't understand immediately. Now I get it. It seems you simply mean to pull out the USB drive.
    However, if I do that, I cannot boot properly. In BIOS settings UEFI is enabled and not Legacy.
    Also, I did not quite understand what you meant by saying to boot from the installation disk, since if the USB is out, it can't boot.
