Thanks for finding that' I had made the mistake of adding "linux" in my searches.

So I tried to run it but now Windoze 10 doesn't boot after the struggles I went through to "repair" the drive after updating the Dell Latitude E5470 BIOS from 1.19.3 to 1.34.3 so it would boot Debian 13. And it doesn't appear in the grub menu even though I set "DISABLE_OS_PROBER=false before running update-grub. I think that's because the disk is MBR, Debian is nonetheless booted as UEFI, and Windoze 10 wasn't installed UEFI (it was installed when I got the computer).  Apparently, if grub boots UEFI it can't boot a legacy partition, and vice versa.
