And there's plenty of jobs where you don't need to move. I mean replying to tickets doesn't require you to be in Warsaw does it? Along with minor site fixes and troubleshooting help before escalating a ticket to refunds....

There are no support positions listed (and doubt someone with programming skills would have any reason to go for one of those), and all software ones list Warsaw.

dual boot is the best approach.

yep win10 and win11beta :P

I once dualbooted Windows 7 and Windows 8 because I wanted to check out how 8 works while still keeping 7 for now (which was good because in the end I hated Windows 8 with a passion).

The Windows 8 installation corrupted the Windows 7 partition unbootable. :( That was some bug or oversight by Microsoft, apparently they had not anticipated someone would try to run both side by side. Windows 8 apparently treated the Windows 7 partition as some extra data partition, and changed something in it to make it unbootable.

So, yeah, no...

Maybe overwriting the hidden system reserved partition?

I don't recall for sure. At first it worked but after some time the Windows 7 partition would become non-bootable.

I recall googling for it and some others had reported the same issue before, and there was some kind of explanation by a MS employee what the issue seemed to be, but I don't recall the specifics anymore...

Anyway, unlike with earlier Windows versions where installing e.g. Windows XP beside Windows 9x dualboot was simple, apparently MS just wasn't expecting anyone to try the same with Windows 7 and 8. Ever since that incident, I've decided I don't try to run two (relatively modern, Windows 7 or newer) Windowses in dualboot anymore.

Agreed, similar issue with macOS 13 with any earlier version. They started using a new filesystem with SSDs, then one version later, number 13 made it work with HDDs, too. Upgrading or installing it converts the whole internal storage disk. As such, installing macOS 12 on an HDD (like the Fusion Drive they sell by default) fails to recognize the new filesystem and reports it empty, so no partitioning the disk without wiping out 13.

I am going with external for all operating systems now, and just plug in a disk and boot the computer. I have only done that lately, with piCore (RPi obviously) and macOS, and those work great that way.

Have yet to try external booting with MS Windows (no copy available, unlikely to get around to trying it at this point), only the free virtual machines with IE and Edge for testing.

I now avoid the internal storage and whatever operating system is installed there, at best just leaving it alone as a worst case scenario recovery system if all the external disks fail to boot (yet to happen).

That macOS thing sounds awful (then again what about it doesn't?). But in terms of multiple Windows installs, I've had them all along, just not in an actual multi-boot configuration. In late 2012 when I first got 7, the Vista install was still there, and in 2015 when I got this computer, I put the HDDs from the other one in it, wiping the Vista partition and installing a fresh 7 on it but not touching the system partition from the other HDD, so that install of 7 is also still around (albeit not functional on this computer if I'd try to load it, I'm sure). And on my dad's computer there have also always been leftovers like this, XP left on one HDD when 7 was installed on another, then that 32-bit XP still left there when the 7 was replaced with a 64-bit XP since something he needed didn't work on 7, and after he did switch to 7 both 32-bit and 64-bit XP installs are still left over. But it's always one OS per disk, with that disk being the only one connected when it's installed, so it doesn't "see" others and there's no multiboot configuration, but if you want to switch to another OS you just go in BIOS and change the HDD boot priority to put the desired one first. Does mean some extra steps and time, so can get tedious if you'd want to frequently switch OSs, but if you either seldom do or really need to use multiple Windows versions and avoid those risks, it can be done this way.
