It sounds like your installation of Prime OS using EasyBCD has overwritten or misconfigured the boot loader, leading to the absence of the Windows 10 entry in the GRUB menu. Let’s troubleshoot this step-by-step to get you back into Windows 10.

Step 1: Repairing Boot Entries with EasyBCD​

1. Boot into Prime OS: Start your computer and select Prime OS from the GRUB menu.
2. Open EasyBCD: Launch EasyBCD within Prime OS. If you don’t have it installed there, you might need to reinstall it or use a different tool to manage boot entries.
3. Add Windows Entry:
   • Go to Add New Entry in EasyBCD.
   • Select the Windows tab.
   • Make sure to select Windows 10 (it might show as installed on a different drive).
   • Click Add Entry and then Save Settings.

     Step 2: Using GRUB Customizer (if available)​

     If EasyBCD doesn’t work, consider using a GRUB customization tool:
   []Install GRUB Customizer:
   • Open a terminal in Prime OS and run:

     bash sudo apt update sudo apt install grub-customizer

   []Configure GRUB:
   • Launch GRUB Customizer.
   • Look for your Windows 10 entry, if it exists but is hidden.
   • If Windows is not listed, you can add it manually using the configuration options provided.
   • Save and update the GRUB configuration.

     Step 3: Check Boot Order in BIOS/UEFI​

   []Restart your Computer: While booting, enter the BIOS/UEFI settings (commonly by pressing F2, F10, Delete, or Esc depending on your motherboard). []Check Boot Order: Verify that the boot entries are correct. Make sure the hard drive where Windows 10 is installed is prioritized. []Save Changes: Exit the BIOS, saving changes.

   Step 4: Using a Windows Recovery Disk​

   If the above steps don't work, you may need to use a Windows installation or recovery disk: []Create a Windows 10 Bootable USB: Use another PC to create a bootable USB drive with Windows 10 installation media. []Boot from USB: Insert the USB and boot from it. Select the option to Repair your computer. []Choose Troubleshoot > Advanced Options > Command Prompt. []Rebuild the Boot Configuration Data:
   • Run the following commands:

     bash bootrec /fixmbr bootrec /fixboot bootrec /scanos bootrec /rebuildbcd

   []Restart your Computer: After this, restart and check if Windows 10 appears in the boot menu.

   Important Note​

   If you use the command prompt for repairing boot files, ensure you follow each step carefully and do not overwrite or delete existing partitions unintentionally.

   Conclusion​

   After trying these steps, your Windows 10 should ideally be back in the boot menu. If you still encounter issues, please provide any error messages you see or further details about the situation. Good luck, and may your Windows 10 boot smoothly!
