To be perfectly honest, IMO this entire thread is a total waste of Garuda forum support time. The official Garuda position on multi-booting is that it is unsupported by Garuda. This is not because multi-booting is unworkable with Garuda, far from it.
Like most Linux distros, if configured properly Garuda works just fine in a multi-boot scenario. The main caveat being, a multi-boot system is only as reliable as the person administrating the system. We really expect that if you are planning to multi-boot with Garuda you should be a competent long time Linux user with many years of multi-boot experience under your belt.
This is not to say a complete Linux newbie is incapable of setting up and managing a multi-boot environment properly because it’s certainly possible. However there is a steep learning curve, and a multi-boot environment is easily broken upon updating any of the OS’s present on the system. At this point (after wasting days of Garuda support time) the frustrated newbie often declares they’re going back to Windows/Ubuntu because Garuda is too unreliable.
With the small size of the Garuda support team we cannot justify the support effort required for something that is essentially not a Garuda issue. We have limited support resources, and multi-boot support threads are like a huge sucking black hole for support time. Multi-boot support issues can be extremely complicated and they waste an inordinate amount of our limited support resources.
If a competent/experienced Garuda user outside the current official Garuda team wanted to take on the responsibility of attending to all the multi-boot support requests then perhaps Garuda’s position would change. Unfortunately, as things stand most support for multi-boot issues still falls on the current Garuda team, (even though this is not our responsibility). Over saturation/burnout of support members is the number one reason for volunteers dropping out of any project. It is their own eagerness to help/support others that is these volunteers undoing. Burnout needs to be carefully managed with such a small team. Therefore, we need to focus our limited support resources on actual Garuda issues.
Multi-booting is not a Garuda issue, and perhaps you need to rethink if it is fair to foist support for such an outdated OS (Windows 7) and hardware onto the small unpaid Garuda support team.
I try not to be too draconian as a moderator, but (fair notice) I may end up locking this support thread if it drags on too much longer.
