I'm having a tough time installing Linux after switching to GPT mode for a game. I got Linux Mint and cleared space on my hard drive that used to have Windows. I disabled secure boot and went through the installation process. Initially, I faced some issues with the partitioning, as I couldn't create the EFI partition. Although the system installed, the bootloader failed with an error message. Later, it unexpectedly worked, but I couldn't boot into Windows or get a GRUB menu. I resorted to rebuilding the Windows boot loader and formatted a mysterious 100MB partition to FAT32, but I'm stuck trying to create GRUB again. I opted out of the dual install since that option didn't show up. Previously, I attempted to install Manjaro but ran into issues. As a side note, I eventually managed to resolve it by using a USB with Ventoy and a boot repair tool, which allowed both Windows and Ubuntu to show up in the BIOS.

You can't create an EFI partition using the Windows partition manager—it just doesn't support that. To set up the EFI boot partition correctly, you should boot from a live CD or USB. That way, you can access the necessary tools.
Got it! I'll boot from USB and see how that works.
