Dell Optiplex 3080 MTP

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

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

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?

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

remove 2.5 ssd. power on pc immediately tap F12 until boot screen comes up. Upload screenshot of what is shown under UEFI>

@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. 

Hi, I want to boot from the NVMe now, how can I achieve this? win 11 repair could not repair it the ssd does not look affecting the system, I have spare external SSD cloned from the NVMe with win 11, but I want to repair the start of win 11 from the NVMe, hope for your help which is very much appreciated.

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 

Sorry to troubled you but still hope you can help, the PC boot sequence now is ( NVME, Windows Boot manager, Onboard NIC IPV4, onboard NIC IPV6, I could not take screen shot as I could not find this option.

I tried the start up repair it shows the NVMe is write protected and chkdsk cannot fix it, but sfc /scannow has found and fix errors and diskpart remove the write protection but it look still there.

The SSD does not appear as an option to use as device so cannot boot from it.

I can boot from windows 11 DVD and it took me to Dell support assistant that ask to downloads cSOS recovery image, I did not continue after that.

I have two USB bootable to win11 detected as UEFI in starting with F12, though one partition as GPT and the other as MBR but still both could not repair windows start up.

If nvme is write protected and you cannot wipe it despite diskpart removing write protection,  it could mean nvme is defective. which brand is the nvme?

Its SK Hynix 256 GB, how it has caused by this USB stick? The PC was running fine before using this USB stick to boot from this USB stick it just did not boot and stop code 0x7B appears.

I removed the write protection with diskpart but it still there though the message say it successfully removed.

Any other way to remove the write protection?

I have seen a WD NVME that is read only despite diskpart removing write protection.  If your nvme cannot be wiped, it may have the same fate. When a ssd is written too many times reaching a failure stage its firmware triggers a lock down mechanism preventing more write, which cannot be reversed by diskpart.  

@draly​  Having 2 or more boot drives in the same PC with the same OS (Win11) is a big Microsoft no-no.  You get a little bit of time to use the drives, like if you want to use Disk Management on the new boot drive to wipe the previous boot drive for storage, and that's about it. Microsoft has it in the OS to corrupt duplicate drives (triplicate in your case).  I went thru this round and round a few years ago until I caught on to it.  It starts with "Disk Checking" and ends up in BSOD.

Remove the SSD and the HDD.  Do a fresh install of Win11 with bootable flash drive created from Microsoft site on a working PC.  During install, delete previous partitions.  Win11 will then make the appropriate new partitions.

After you have your NVME set up and working, power off.  Install HDD.  Boot from NVME from the F12 Boot & Diagnostics menu.  After booting, immediately go to Disk Management.  Wipe the HDD.  Simply reformatting it, even if formatting to the same system and file scheme, wipes it.  (GPT and NTFS preferred as redxps mentioned.)  You can now use the HDD for storage.

Reminder:  All important files/data should be backed up outside of PC.  So, if need be, and your SSD still boots, do it without NVME and HDD installed.  Backup your important stuff.

Up to you what you want to do with the SSD.  If it boots, saving it for backup isn't a bad idea as redxps mentioned.

If you want more than 1 boot drive installed with Win11, you'd need a system that has 2 or more 5.25" bays that you can install hot swap HDD/SSD with switches.

My Win10 PC is a Precision 3620.  (Not supported by Win11 by the way.)  I have 2 hot swap bays with switches installed.  One bay has an SSD with Win10 and the other a WD Velociraptor HDD with 10 (different builds).

I didn't explain something quite good enough.  During Win11 installation, it'll get to a screen that asks what partition you want Win11 on.  That's when you delete previous partitions.  Click on Next, then appropriate partitions are made and Win11 continues to install.
