Intel to AMD, MBR to GPT, Secure Boot Windows UEFI + CSM Disabled BSOD

Question

• Build this computer in 2016 using Intel and Windows 7
• At some point I upgraded to Windows 10
• In 2021 I swapped Intel for AMD
• I did not do a fresh install of Windows 10
• Recently I wanted to upgrade to Windows 11
• I enabled TMP 2.0
• I used mbr2gpt and after some troubleshooting I managed to switch my drive to GPT
• Upgraded to Windows 11 successfully
• However I cannot boot into my system if I enable Secure Boot Windows UEFI in my BIOS
• I am met with two bluescreen issues:
  • 1: "A required device isn't connected or can't be accessed. 0xc000025"
  • 2: "The operating system couldn't be loaded... File: \windows\system32\DRIVERS\iaStorF.sys Error code: 0xc0000428"
• If I choose "Other OS" in my motherboard Secure Boot settings I can boot into windows successfully
• I have tried to rename and even disable "iaStorF.sys" but doing both will prompt me with a BSOD QR code error

Minidump issue:

My minidump never writes BSOD errors unless they happen while I am in Windows. If I BSOD before entering Windows I do not see a dump file in my minidump folder

All graphical, chipset, and motherboard firmware drivers are completely up to date.

Windows 11 is up to date as well.

Answer 1

Hello

Have we verified present device hardware is compatible with Windows 11(the device manufacturer website has the Windows 11 driver for this machine model)?

"iaStorF.sys" refers to " Intel Rapid Storage Technology driver". Try to download the latest verison from the intel website.

Anyway, I found a similar case. A fresh install may be an option. Or we may consider to work with secure boot disabled.
