I am planning to spend a few days at my friend’s place. My friend has an Intel-based PC, whereas my PC is AMD motherboard+CPU. Is it possible to take out the SSD in my computer and insert it into my friend’s computer hoping Manjaro to run as is ? I mean, will my Manjaro installation be able to boot off a different motherboard and CPU and work well enough ?
Yes it is possible. But you need to boot with the fallback image. You can select it in the grub menu.
The CPU is usually not the main problem. The GPU drivers are, specially if the nvidia driver is involved. If all systems use the opensource drivers, there is no problem. But if any special X configuration is required, the boot might stop without a GUI. You need the switch to a tty and go from there.
As an alternative, a live manjaro system.
I’ve used UNetbootin to create a bootable Live USB drive. Make it persistent, so it remembers your changes.
Although it doesn’t look like manjaro is supported
