Access Windows 10 using GRUB rescue by restarting your system and pressing the appropriate key during boot.
You removed the Debian partition without deleting the GRUB installation, and now booting into Windows causes issues. There’s no direct fix to restore your data without reconfiguring the system, but you can try reinstalling GRUB or creating a bootable USB to recover your files.
Launch a Windows startup fix. Power on via Windows 10 disk or USB stick, choose the language, select the repair choice instead of installation. You'll get the startup repair feature.
Let us know if it worked or not. It seems you were really worried about your data. You should always have a backup. Because, things can go wrong—your HDD or SSD might fail, you could get ransomware, or an accident might happen and you accidentally delete important files... etc. Backups are essential, and they save you from many problems (and the stress of trying to fix things later). Don’t worry about sharing your thread title; everyone will see it. In fact, asking for help is the right thing to do.
It doesn't really matter if you use a 32-bit or 64-bit boot drive.
But why do you require the key? It seems you're either setting up Windows 10 from scratch (so this isn't needed because your data will be removed) or switching to Windows 10 again (which might solve the issue, though I haven't tried it with systems lacking a boot loader).
I understand you're getting a boot drive from Microsoft's site instead of having your own.
