Hi all,

I'd love some assistance. I've spent days on this and just found this forum and it's given me some hope.

I can get to a Command prompt only from BSOD when trying to Boot Windows 10 64Bit from a Samsung SSD drive.
BSOD happenned suddenly a few days ago and I don't know why.
No other Windows Repair options work from the Bluescreen options and no safe mode.
Last resort seems to be a reset or re-install but hopefully you can help me.

Startup Repair diagnosis and repair log =
Root cause found:
---------------------------
Boot critical file e:\boot\resources\custom\bootres.dll is corrupt.

I have used another boot drive that has Windows 7 on it in the same computer and can access to the Problem Windows 10 drive and it's files through Win7.

Can I use the 'Sysnative BSOD Dump + System File Collection App' from the Windows 7 installation for the Windows 10 disk which is e: drive?

Or should I try to boot that Windows 10 drive and then get to the command prompt from the BSOD and try to run 'Sysnative BSOD Dump + System File Collection App'?

Or whatever you may sugggest.

Thanks!!!

Yes please try this as the first step. What happens when you try to start in Safe mode? Have you tried all the safe mode options such as:

Enable Low resolution video
Disable driver signature enforcement

At a minimum, copy out the \windows\minidump folder from the Windows 10 partition; zip it up and attach to post.
