I installed Ubuntu 18.04 along with Windows 10, for some reason it didn't recognize the Windows EFI (which is in a SDD, Ubuntu doesn't even recognize the SDD). The thing is, I can run both OS fine, but when I start my PC it goes straight to Ubuntu, if I want to run Windows I have to press F12. I there a way to go to the boot menu and choose with OS I want to open?
Edit: I just want to be greeted with this when I turn on my PC (UEFI Boot Menu on Dell)
I had a similar issue and it was because I had installed Ubuntu using bios mode but Windows using efi mode.
This explains how you can check if ubuntu is in efi mode: How can I tell if my system was booted as EFI/UEFI or BIOS?
There was a way to convert an existing ubuntu install from bios mode to efi (which is what I did) but I'm having trouble finding it now.
Edit: https://help.ubuntu.com/community/UEFI << Scroll down to "converting ubuntu into uefi mode"
