Other OS

Wed Jun 14, 2017 5:44 am

Is it possible to boot another OS from an external drive using a Raspberry?

For example: If I have Fedora or Opensuse or Windows XP installed in a external hard drive and I want to boot that OS into Raspberry as I do in another computer

Any bootable kernel can be on a USB drive. What gets started when the bootcode starts the kernel is independent of what medium it was loaded from.

It has to be an ARM6/ARM7/ARM8 kernel. Your RPi can't boot any old hard drive (which probably has a Intel x86 or x86_64 kernel).

He means no.

Windows on another drive will not boot on a Pi, neither will most Linux OS's.
Only kernels/OS compiled for ARMv6/7/8 will boot. 7/8 won't boot on a ARMv6.

Could a Pi use QEMU and boot another OS from the drive?
Er maybe. I would not like to try on any except a Pi 3.
Boot an external 64bit x86 OS on 32bit Raspbian QEMU, probably not.
Serious code fu needed.
Maybe one day/year/decade?

If you can do it, go to Cambridge and pick up your CS degree.

Time to revisit, they are already running 64-bit.

I have tried most months ago, perhaps time to revisit.
Maybe they are quick and easy to install and fast to boot?

That is what I'm studying. I'm not really working on something that is unrealistic. I will like to run an OS say openSuse armv7 on a usb drive and save my work on it. Not looking for profit, fame or even glory. Just want to get things done and share it. Read people's criticism and accepting it.
