major booting issues for a totally blind user trying to boot debian 12.6 and windows 10 pro 64 bits on different drives with uefi booting



Hi, I have installed debian 12.6 successfully on my System76 Serval WS 11 
laptop on the first nvme drive that is two terabytes.  On the second drive 
I have windows 10 pro 64 bits which is also two terabytes and have two 
more drives that are four terabytes in size.  All drives including the 
windows drive and the other storage drives are mountable and I can access 
their data.  During the installation grub told me that it can modify the 
nvram to have grub boot into debian by default but I told it no as I am 
totally blind and had someone set the uefi boot order so that the windows 
drive was booted first.  Now when I reboot I hear the grub beep and no 
windows option and os-prober is running as it told me that it could not 
detect any other operating systems during installation.  I did some 
reading and it appears there is an esp partition that contains the efi 
boot files which only exists on the first nvme drive with debian and no 
windows efi files exist.  I did look in the windows partition and found 
lots of .efi files and tried copying bootmgr into another directory 
/boot/efi/efi/windows that I created but no luck.  What method can I use 
to repair this system so I can use the system where debian does not even 
touch windows and where I can easily choose the windows boot option or 
make it the default as update-grub says nothing about this issue and no 
os-prober output is given if I run it as root I just get put back to the 
shell?  Does debian or another service besides Aira which is paid and does 
not really know much about linux exist where I can do a video call or some 
type of remote access where they can remote into this linux system to try 
to fix windows?  Nick Gawronski
