Several machines sharing one storage device
Several machines sharing one storage device
Trying to combine all storage into one drive while keeping each computer’s boot option flexible is challenging. You’d need a setup where the SSD can be used directly for booting without relying on internet or complex configurations. Consider exploring dual-boot methods or partitioning tricks that let you select the OS at startup. If you’re open to alternatives, look into lightweight virtualization or cloud-based solutions.
It seems the system could manage this easily, with just three installations on one drive. It won’t differ much from a triple boot on a single machine.
I hoped for a solution similar to grub, but I believe it won’t work. The challenge is that the three computers use different CPU architectures, making it more complex than just installing it multiple times. My issue involves one PC needing ESATA support and another lacking internet access.
The bootloader works independently of the architecture. Once started, installation can proceed with system-specific drivers.
It seems unlikely without a hypervisor to divide access to the storage device. You might consider using high-speed USB3 drives for booting, which would improve speed while keeping things portable—opting for three USB drives instead of one large HDD would be more convenient.
