this is a cold boot issue
why this is happening is
when cold the ram isnt stable, on first cold boot its failing ram training/stability due to the ram being colder and not getting enough voltage in post
when in windows its warm running and getting nice smooth higher voltage

when you cold start it its not hence the boot loop and reset

options are
select slower ram speed and/or looser timings

or

configure it windows stable and SAVE THE PROFILE IN BIOS

either way manually setting all configuration is a needless waste of time


Thank you so much

I know the issue now, I actually turn off my UPS and my AVR right before I sleep, thus it cuts all the voltage to my CPU, after further experimentation, changing the RAM speeds and timings then leaving the UPS on does not result in double boot.

Thank you so much for the help everyone!

Check this guide. Seems to fix exactly that issue for a lot of people.


I honestly did not understand most of what they disccused on that thread , though I tried to changing the voltages as one person said that worked for him, it did not work on mine.


I had same problem. I changed SOC and both VDDG voltages and it disappeared. Now I don't have any boot loops and my bios settings aren't reset on a boot after a night.

Boot issues
I have noticed that sometimes the problem stems from other settings being left on Auto such as SOC and VDDG Voltages. I Originally suggested at least 1.08-1.1 for soc However I have since found with the correct ram settings in place I can run 1.05 on SOC and 1.03 on VDDG voltages with no loss of performance. Never run your VDDG higher than SOC you will cause loss of performance. The only way to truly test what an ok voltage is to run a cinebench if you run one on auto voltages then another on lower voltages you should see no difference in performance. Also note that the boot order sometimes tends to forget itself. Make sure you have only the drive you want to boot from in the boot order if you have an Boot Partition left over on an old SSD and get rid of it.
