Dell Optiplex 3080 MTP

How can I create bootable USB for this system that can boot as GPT or MBR? it is installed with Windows 11 pro x64 on NVMe M2 drive with GPT NTFS partition?

    Sounds like you're getting the hang of it.

    Yes, once you have a bootable NVME or SSD, reformatting the HDD wipes the OS.  Best to use GPT format and NTFS file scheme.  If HDD is already formatted to that, reformatting the same still wipes HDD.

    HDD currently can be used to wipe NVME as long as NVME isn't write protected.

    For UEFI bootable usb you can use Windows create recovery drive method.

    3080 bios does not support legacy boot.  It supports UEFI bios only.

    @redxps630​ 

    Hi, many thanks for the reply, what I expects to happen if I try to boot from USB stick bootable in MBR?

    I have three disks in the PC HDD with GPT partition and NVMe M2 with GPT partition and SSD with MBR partition, the PC can boot only from the SSD but not from the NVMe or will not boot to windows and make Stop code 0x7B.

    Any way to fix this?

    a UEFI BIOS can boot from an MBR-partitioned drive, but it is not standard, often requires special configuration (such as a FAT32 partition for EFI files), and is generally discouraged in favor of GPT.

    The PC is now booting from the SSD only, how can I set it to boot from the NVMe or the HDD both are GPT.

    Is it possible that the USB stick has made some changes to the settings?

    Thank you

    @redxps630​ Yes I can do this, I can take snapshot before and after removing the SSD if you require.

    But why to remove the SSD? the PC does not boot from the SSD direct it boot to the stop code or to start up repair then offer to boot from other devices, the NVMe, the SSD, on selecting the NVME it does not boot, on selecting the SSD it boots to windows 11 readily.

    The SSD is cloned from the NVMe and the NVME cloned from the HDD which is the 2 Tb.

    not sure what you want to accomplish with three storage devices in installed. Do you want to be able to boot from any of the three devices?  
    if they all have same OS and apps, default is to choose nvme (fastest of three) as boot drive and the other two as data drive without OS. If you want to save a copy of boot drive in ssd in case you mess up the nvme, then remove the 2.5 ssd place it in drawer as true “back up” so you don’t accidentally mess up the back up too.

    If 2.5 ssd can boot then you can try clone the ssd to nvme ssd.  I use create system image of ssd on external usb hdd then restore image on nvme.  you need a small usb recovery drive to boot pc before you restore image on nvme
