Hi, welcome! You're setting up a dual boot between Ubuntu and Windows 10 on your laptop. Initially, after installing Windows on a separate SSD, the GRUB menu didn't show up. To fix this, you restarted and selected the Ubuntu drive in boot options, which worked. You then updated GRUB to include Windows again. In BIOS, you adjusted the UEFI boot order so Ubuntu's drive comes first. Now Grub appears on restart, but you still can't boot into Windows—you encounter a blue screen. P.S., after changing the boot order in BIOS and successfully booting into GRUB once, the error started recurring.

It seems Ubuntu affected your system's reserved partition. Create a bootable Windows media in Ubuntu and start from it. In the Windows Command Prompt, enter these commands: bootrec /fixboot bootrec /fixmbr bootrec /scanos bootrec /rebuildbcd. If that doesn't help, run Startup Repair. If it still fails, reinstall Windows without disturbing your Ubuntu partition and make a recovery disk, choosing Boot Repair when Ubuntu boots. Hope this assists you.
