When you boot to alternate media are you booting as UEFI.

I wonder if the Dell updater was in any way involved in the situation with you and all the other XPS 13 93XX systems?

As far as repairing it, you might think about doing the Bios recovery, if that system can do it.  If there was some problem with the first install maybe a manual second one would correct any problems.

I have no idea what caused the issue in the first place (this is somewhat concerning).  But after time spent with phone support, I did resolve the issue.  Here are the steps to correct if it helps others:

-  put the SATA mode to AHCI (from Raid On)

-  boot to windows 10 recovery/install media

-  select repair startup (this step apparently doesn't work on the On Raid setting)

-  on reboot, the system bluescreens with a not accessible message (this is expected since the OS was installed with Raid and not AHCI)

-  change SATA mode back to Raid On

-  ***.

the SSD was not getting recognized in the OS.  I do not know what the automatic start-up repair did other than switch around the boot sequence.

Hi Brandon,

Welcome to our community. Thank you for updating us with the troubleshooting steps performed. If you are comfortable in removing the HDD, please go ahead and use the same hard drive in a different system and check if the hard drive is detected. This is isolate if the issue is with HDD or with any other with the system.

Not sure... the device in device manager now shows as NVMe... Perhaps some kind of reset caused the NVMe controller to wake up and acknowledge the device.

Device SCSI\Disk&Ven_NVMe&Prod_PM951_NVMe_SAMSU\4&777aad5&0&050000 was migrated.

Thank you for the update Brandon. We’ll surely take a note of the resolution provided. If there are any other issues that need to be addressed in the future, please feel free to write to us.

I think what you did was move from the NVMe controller to the SATA controller.

Hi Brandon,

I am having the same issue as you had.

Could you please explain how you did the "boot to windows 10 recovery/install media" ? how do I boot to this? i found how to change from raid to ahci in the F2 menu, but not the win10 recovery.

Did you see the "select repair startup" option in the recovery/install mode?

Any help is highly appreciated.

Thanks,

Guy

Run the media creation tool to create a bootable USB stick. When it boots, click repair, then fix startup.

I just want to put out there that I had the same exact problem happen to me about 2 hours ago. I'll try to replicate the solution as described by Bcr5 and post whether it worked for me as well.

It's ridiculous that a BIOS update put out by Dell has rendered my device unusable. What's the point in investing in these expensive machines if the updates are only going to cripple them? How can a company release updates without bug checking!?

UPDATE: I tried replicating Bcr5's steps to fix the issue, but it did not work for me.

Before I could boot from the USB recovery media, I had to enable Legacy booting (this included turning off Secure Boot and enabling Legacy ROMs). Only after Legacy booting was enabled did my machine show the USB drive in the boot sequence, allowing me to move it to the top of the sequence stack. In UEFI mode, the USB did not show up, even though I tried with multiple USBs.

Once I was able to boot the recovery media, I clicked "Repair your computer". After clicking Troubleshoot --> Startup Repair, Windows attempted to diagnose the issue, but ultimately said, "Startup Repair couldn't repair your PC". I even tried the other recovery options, like switching to a previous build, system restore,  ect., but Windows stated there were no system images.

Any suggestions on what my next move should be?
