Zorin stuck at grub> at startup in dual boot system

I have an older Windows computer that has one drive with Windows 7, one drive with Windows 10 and a third SSD with Zorin 18 Pro. Bios is not set to UFI mode. I used EasyBCD to set up a triple boot configuration, which has the bootloader pat set to \NST\AutoNeoGrub0.mbr
When I start the computer with the \NST\AutoNeoGrub0.mbr bootloader, the computer winds up with grub> I do not know how to proceed.
I'm sort of in the blind because I do not know how to see the Zorin files with Windows.
I ran a Linix boot repair disc and it generated the following report:

boot-repair-4ppa2081                                              [20251105_0002]

============================= Boot Repair Summary 
==============================






Recommended repair: ____________________________________________________________

The default repair of the Boot-Repair utility will reinstall the grub2 of
sdc5 into the MBR of sdc.
Grub-efi will not be selected by default because legacy Windows detected.
Additional repair will be performed: unhide-bootmenu-10s


/boot/efi removed in sdc5/fstab

Unhide GRUB boot menu in sdc5/etc/default/grub

======================= Reinstall the grub2 of /dev/sdc5 =======================

chroot /mnt/boot-sav/sdc5 grub-install --version
grub-install (GRUB) 2.12-1ubuntu7.3+zorin2

==> Reinstall the GRUB of /dev/sdc5 into the MBR of /dev/sdc

chroot /mnt/boot-sav/sdc5 grub-install /dev/sdc

Unhide GRUB boot menu in sdc5/boot/grub/grub.cfg

Boot successfully repaired.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sdc (ATA CT1000BX500SSD1) disk!

The boot files of [sdc5 (end>100GB)] are far from the start of the disk. Your BIOS may not detect them. 
You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be 
performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of 
[Boot Repair]. (https://help.ubuntu.com/community/BootPartition)

============================ Boot Info After Repair ============================

 => Windows is installed in the MBR of /dev/sda.
 => Windows is installed in the MBR of /dev/sdb.
 => Grub2 (v2.00) is installed in the MBR of /dev/sdc and looks at sector 1 of 
    the same hard drive for core.img. core.img is at this location and looks 
    for (,msdos5)/boot/grub. It also embeds following components:
