Encounter problems during Arch Linux installation involving grub and os-prober?
Encounter problems during Arch Linux installation involving grub and os-prober?
I installed Arch Linux to try a few Linux distributions. My old Lenovo Legion Y7000 worked well during the setup, but I’m planning to run Arch on my custom PC now. I followed the Arch Wiki instructions, and everything proceeded smoothly until the grub bootloader installation phase. Since I’m currently dual-booting Windows and Pop!_OS and preparing a triple-boot setup with Arch added, I used os-prober to identify other systems and update the grub entries. It recognized Pop!_OS when the partition was mounted but didn’t find Windows because it wasn’t mounted. Now, after trying to load the grub configuration, only Pop!_OS appears in the output, even though Arch is installed and mounted. The boot options under Arch root partition show no sign of Arch Linux at all—just Pop!_OS, advanced settings, and UEFI firmware details. Could you help me troubleshoot this? Any suggestions would be appreciated.
