Question Windows 11 boot-loops on a dual boot system ?

[ShoneRL]

Hello,

My friend wants me to install W11 on a new NVMe SSD and still keep his original W10 on another drive, then eventually move stuff over to the new W11 installation.
It's a B550 AORUS ELITE V2 Motherboard system with fairly newer hardware, it meets the requirements for Windows 11.

I spent hours trying to install W11 off a USB stick, what happens is that whenever Windows 11 is installed, it pops up as a dual boot option but if I select it, the PC just restarts.
W10 still boots properly though.

Things I tried to fix the problem:

• Updated BIOS.
• Disabled / Enabled CSM support.
• Used both the Media Creation Tool for Windows 11 and Rufus to try and create ISO.
• Checked the USB stick for bad sectors.
• Enabled TPM, reset TPM keys too.
• Enabled / disabled secure boot.
• Used diskpart to remove partitions, clean up the SSD drive and convert it to GPT for W11.
• Disabled/Enabled XMP.

Nothing has worked so far and I'm at my wits end, even with Rufus allowing to install W11 without forcing hardware requirements, it still wouldn't boot.

Any idea on how to go about solving this?

When you say "The PC justs restarts" , does it boot up to the dual boot screen again or constantly boot loops until shutdown and power on again?

It boots back up to the dual boot screen prompting me to select the OS, then I can choose to continue with Windows 10 (which works) or Windows 11 (which restarts again as far as the dual boot screen).

The bootloader on windows 11 drive could need repairing. Its best to only have one hard drive in the pc when installing an OS. Otherwise it can cause booting problems, and even data deletion etc on the usable drive.

Try these options, but good idea to backup windows 10 drive before using these options to backup any important data on existing drive !

KingLoki’s totally right about the bootloader on the Windows 11 drive. There’s a chance the Windows 11 boot files aren’t fully configured due to the dual drive setup during installation, which can confuse the system. I’d suggest trying KingLoki’s recommendation to temporarily disconnect the Windows 10 drive and repair the bootloader on the Windows 11 SSD using a recovery USB. This helps prevent the dual-drive conflicts and might get Windows 11 to boot smoothly.
