How do I boot back into windows ?

[Justaphysicsnerd]

so I followed the tutorial present at https://www.freecodecamp.org/news/how-to-dual-boot-any-linux-distribution-with-windows/ to install linux in a dual boot setup with my windows installation except....when I chose the EFI partition it said it was too small so I had to make a new one of 1 GiB and now when I boot, I don't get that GRUB bootloader screen to let me choose which OS to boot into, how do I fix this ?

Grub may just need to find Windows again. Boot into linux, and then you can try e.g. this as the simplest attempt: https://askubuntu.com/questions/197868/grub-does-not-detect-windows

sudo os-prober
sudo update-grub

When I type in sudo os-prober it says command not found, what does that mean ?

so an update, I got back into windows by pressing Esc repeatedly which brings up a different BIOS screen (pressing F10 brings up another BIOS screen both are sorta moderny looking UEFI screens though) and from there I could select in the boot options menu whether I wanted to boot into Pop OS or windows. I am on a 2020 HP Omen 15 btw (the one with Ryzen 4600H + 1660Ti)

Also now that I reeboted it put me back into Pop OS without selecting anything from that BIOS screen

You can try installing it with "sudo apt install os-prober", though I notice it's disabled on the Grub 2.06 by default so there might be more work needed depending on the Grub version you have.

Sometimes it's a matter of what exactly is selected as the boot device in the BIOS. Check your BIOS boot order and see if another option gives you the GRUB menu. I know both Windows and Linux today sometimes create their own boot menu entry instead of the device itself they're installed on. See if that produces a different result.
