There is a section here on dual booting using systemd boot. Never used it, but it will hopefully work in your case, or at least point you the right way.https://ostechnix.com/dual-boot-windows-and-pop-os/

Is the router wireless too? If so I would connect my phone to it and when you get an outage on a computer, check if your wifi is working. If it is, it’s something in the hardwired components. But if the Internet connection drops on wifi too, you know it’s somewhere in the router or past that to the external network. Have you power cycled your network equipment? Any chance you have a laptop handy? You can test right at the switch or at the router when your computers drop.This will help narrow down where to look further.

If you can’t change your DHCP pool, can you reserve the IP you want for the device in the router? You should be able to at least do that. That doesn’t answer the question as to why you are having problems, but it will get you going, and if you can’t change the pool, will prevent the router trying to assign something else to that ip. If you reserve in your router, be sure to change the setting back to DHCP in your windows device. Sounds like either another device is picking up that IP or your settings are off. If you want to stick with setting on your device, have you tried retyping everything in the network settings? What I mean is, completely delete every field, ip, subnet, gateway, dns, and retype. Verify it’s accurate. Then open cmd as admin, then release/renew and reboot or at least flush dns. It’s pretty easy for your brain to overlook an incorrect setting, when it wants to see the correct one. Happens to me all the time, lol.

Check here if your hardware is supported https://www.vmware.com/resources/compatibility/search.php?deviceCategory=io If it isn’t you might be SOL, but can always look up answers specific to your hardware and esxi version. I assume you’re running Esxi 8. May have to change your hardware. If this is for learning esxi for work/job stuff you need to invest in compatible hardware. If it’s just to have a host, try proxmox or something compatible with your equipment. Anytime you install something like this, you need to check compatibility. Also, for future reference, when asking questions of this nature you should provide more info. Like hardware you’re using, version of the installation, exact error message, where in the process this error occurred,installing to bare metal or in a VM. A solid answer will depend on the information given. A lot of people don’t even want to interact with someone who gives so little information to the problem. There are too many variables.This isn’t a dig at you, you probably didn’t know, just trying to help you out in the future. Good luck!

Open it up and check. Is this your model? https://pcnight.com/desktop/dell-optiplex-3060-micro/ Looks like it might, but I don’t have one on hand to verify.

Most of the time you will probably be okay mixing. That being said you can have issues. Are there different latencies on the ram? With the speed difference your ram will run at the lower speed. If the latency is different the ram will run at the higher (slower) latency. As long as the modules can scale to these differences you’ll be fine. I’ve mixed tons of ram before and never had a problem. But others have. And the only reason I mixed was because it’s what I had lying around or acquired for free. If it were me, when buying the ram, I at least match all variables(speed, latency, voltage). I would go with the team group. If you mix and nothing goes awry, then no worries. If you mix and something goes funky, then that’s time and even more money you waste.
