Installed bios TUF GAMING X570-PLUS (WI-FI) BIOS 4408 and after, the unit refused to boot into win 10 even after changing bios to secure boot. Turned off secure boot, no change.Also the grub menu disappeared, replaced with Minimal bash-like command line. Main setup screen sees all hard drives, but win 10 drive is missing from boot menu, only ubuntu remains. reinstalled 4408 bios, no change in symptom, & no I did not back up/image drives.

Does a file need to be added to win 10 boot sector? It does not even try to boot into win 10.

At this point I’m at a loss as to a next step , if these is one.

What is the model of your Asus motherboard?  It’s more than likely that you do not need the TPM 2.0 SPI add in card, but rather you just need to update your motherboard bios to the latest version, and enable TPM in the motherboard bios.

See https://www.asus.com/microsite/motherboard/ASUS-motherboards-Win11-ready/

I would also look in your motherboard bios so see what your boot drive is.  You should be able to change it to boot from your Ubuntu drive if you had been booting from it previously.

Ok I found the AMD  listing for the 570 & it has a link to updated Bios & driver. Will update both.

Thanks Paul T,

That’s encouraging. See my reply to Klang for mobo info

Searching the ASUS ready for win 11  chart on the web site linked in original response. I see no mention of this  X570 moboard. g² Procesor chip is a Ryzen 9 3900

Thanks for the quick response.
