Windows 10: INACCESSIBLE BOOT DEVICE error in BSOD at startup

axe0 there is only 1 HDD - disk 0 under 'list disk', partitioned as listed above. My usb shows as disk1. That's it.

 

Some procedures are different if the partitioning scheme is MBR compared to GPT.

EDIT: nvm, I think I know it.

 

This may be a silly question to you, but have you tried booting into safe mode?
Could you run the following command and provide the output
Code: bcdedit /enum all[/quote]

 

So F8 during boot doesn't offer a menu to choose safe mode. And as I noted above, choosing any option (including #6 'Safe Mode Command Prompt') from the menu of 9 Startup Settings which now presents following whatever Macrium Reflect screwed around with, loops back to the "...we ran into a problem" initial BSOD.
As you can see from the screenshots below, I entered "bcdedit /set {default} bootmenupolicy legacy" to enable the F8 familiar legacy boot options after POST. But choosing '1. Safe Mode' doesn't boot into Safe Mode, but results in the same initial BSOD.



Perhaps changing to the legacy boot options was what you had in mind anyway?

 

Please remove the assigned letter to the System Reserved partition
Code: select partition 1 remove letter=I <-- uppercase i[/quote]

 

So I know it usually presents as X:, but the above screenshot was from when I booted from my install usb, which was allotted d:
System Restore was given the last one in the sequence - I:
And after I have removed it, do you want me to replace it with anything? What should I expect will happen after removing its assigned letter? Do you want me to take any follow-up actions? I'm just a bit puzzled axe0, as to what to expect...

 

The System Reserved partition is a partition that shouldn't have any letter, it contains the BCD, Boot Manager Code, Windows Recovery Environment and space for startup files for bitlocker (if available).

With a little bit of luck, you'll be able to boot again.

 

Hi okkid,

How's it going?
