I bought a new m.2 SSD so i wanted to install the OS in it. The thing is i did the process of installation in this new SSD while the old SSD with an OS installed was conected to the PC. When i finished installing using an USB and i tried to change booting options from BIOS i couldnt find the m.2 as UEFI and what i did find was the old SSD but with "Windows Boot Manager" added to its boot option. So when i tried to boot the system, Windows Boot Manager pops up and i have to go through it every single time i turn the PC on (eventhough it allows me to boot Windows 10 installed in the m.2). If i try to remove the old SSD and boot the m.2 alone (it isnt a UEFI boot option) it says it is not bootable or sth similar. What im trying to solve or to achieve is being able to boot from the m.2 without needing the old SSD to get Windows Boot Manager and then i can start up the OS in the m.2.
