The setup process encountered an error during Windows installation.
I apologize for my unclear English—I'm French. I attempted to reinstall Windows by uninstalling the original version from Acer and installing a new one. However, the setup process didn't go as planned. I'm using a Nitro AN515-51 with the installer on a 64 GB drive, aiming to install Windows 10 on a 120 GB SSD. I placed the media file from another Windows machine onto my PC, selected the language and partition, and chose to install it on the entire disk after formatting it completely. The installation ended up creating two partitions: a system partition and an MSR (reserved) partition. The 120 GB partition is now present but isn't empty—it's a primary or main partition. I deleted it and restarted the installation, which worked fine. However, when I tried to delete the partition again, the button turned grayed out, and the installer displayed an error saying the installation button was also grayed. I've tried Diskpart, Rufus, Ventoy with ISO files, MBR or GPT formats, but I'm unsure what to do next. If anyone has suggestions, please let me know. (Also, I'm using UEFI.)
