[SOLVED] upgraded to 3700X - now Win10 won't start

[Alonleibo]

Hi guys,

My PC was:
Ryzen 1600
Corsair Vengeance 2x8GB 3000MHz
Gigabyte X470 Ultra Gaming (BIOS F42d)
Samsung 970EVO 500GB
SP 1TB SSD
Corsair RM750

Today I upgraded to 3700X + G.Skill TridentZ RGB 2x16GB 3200MHz

system boot goes fine (all 4 LED's check OK).
but then the system gets to the AORUS logo screen and loops in it (occasionally it also writes "preparing automatic repair" and loops in it).

it did boot once after a couple of times.... after a REALLY LONG TIME looping. but since then - nothing. doesn't boot anymore.

tried the Win10 flash boot media as repair tool - doesn't work.
tried to boot Ubuntu from USB - works fine.

any other options besides re-installing windows?

Did you reset CMOS after CPU change ?

What was the version of BIOS installed BEFORE you updated to F42d?

Seems like you're out of options if you can't work with a recovery drive. Like my colleague, I'm also curious to know what version of the BIOS you were on prior to the update.

Did you reset CMOS after CPU change ?

did.... "factory default" in the bios.
is that good enough or taking the battery out?

did it step by step, version by version.
F30 -> F31 -> F40 -> F41 -> F42d

did it step by step, version by version.
F30 -> F31 -> F40 -> F41 -> F42d

During those steps, did you make sure to install the other necessary updates?

Before update BIOS to F40, you have to install EC FW Update Tool (B19.0517.1 or later version) to avoid 4DIMM DDR compatibility on 3rd Gen AMD Ryzen™ CPU

F30 - Note : Update AMD Chipset Driver 18.50.16.01 or later version before update this BIOS

F5 - Note : Update AMD Chipset Driver 18.10.20.02 or latest version before update this BIOS.

I'm 99% sure I did as instructed (it was ~2 weeks ago, so i'm not 100% sure).

it does identify the 3700X + RAM.
it DID boot into WIN10 once (after a long time).
it does boot into Ubuntu.

What about drivers, did you update chipset drivers too ?

Update:
So, I just flashed F41.
now win10 DID START.

going to Restart the PC. wish me luck.

Ok so it's up. for now.....

few questions about a couple of settings in the BIOS:

1. "other PCI device rom priority" - what should it be?
2. "storage boot option control" - what should it be?
3. in "fast boot" menu - what settings should I pick? (for the VGA for example - EFI or auto?)

I'd offer the advice I give myself. If I don't know what they are, leave them at the default settings.
