On my dual boot machine:
-Windows 11: 60-240 seconds before I am connected to WiFi and can open a browser to my home page
-Ubuntu 23: no delay, it just starts.
-Windows 11: 60-240 seconds before I am connected to WiFi and can open a browser to my home page
-Ubuntu 23: no delay, it just starts.
My long boot times are with POST-phase DDR5 memory training. Takes around a minute before I can get to the bootloader. I have tried many BIOS settings to try to cut that part down but haven't been successful (usually results in a crash).
Another datapoint, I also have a Framework Ryzen 13 and I don't recall seeing delays for my dual boot setup either to Win 11 or Ubuntu 23. But, I think I do sometimes have DDR5 training lag times as it's also a 64 GB system.
Without EXPO turned on the length of the POST-phase is basically zero when I turn on memory context restore.
But with EXPO turned on my PC basically won't boot (as in, I'm too impatient to wait more than an hour).
So I just keep EXPO turned of, as 4800Mhz vs 6000Mhz RAM in practice doesn't make much of a difference (for most tasks).
EDIT: nevermind, I just tried enabling EXPO again, and it seems like the memory context restore option now even works with EXPO enabled, so POST is still very short. I'll keep it on and see how it goes.
I also read somewhere that one needs to POST multiple times for the context restore to kick in, which could make sense in my case, as I left it on with EXPO disabled and now it does not memory train any more even with EXPO disabled (at least the POST screen is only visible for like a second and then my OS boots up).
But when I set up my system I spent much time fiddling around with the BIOS, so I'm not 100% sure if it is memory context restore that solved this in my case.
Also there is no delay with wifi, once it starts that all works immediately on both OS's.
