I recently installed Ubuntu 24.04 L.T.S. I had a lot of problems during installation but now, I just can't boot up windows. Even if i give it top priority through BIOS, Ubuntu somehow keeps opening. I'm not shown the choice of choosing which OS i want to use. I have tried almost everything. from ChatGPT to shady websites and forums. I have a Lenovo Ideapad 3 computer by the way.
This is like, really urgent. I have tons of important files on Windows, I can't access them through Ubuntu and I'm just afraid I'll lose them forever. About wiping out Windows, I can see the Windows booloader at the BIOS priority selector, but even if I put it first, Ubuntu is the one to load instead of Windows
Edit: As David asked, all problems during installation were resolved. I selected to install Ubuntu besides, not instead of, my current OS, Windows 11. About wiping out Windows, Windows bootloader is visible in the priority list, but Ubuntu no matter what comes first
