Windows 10: 2 x Windows 10 on Dual Boot - 1 OS will not Start/Repair/Reset etc

Hi, I'm kind of at the end of my tether having tried various solutions over the web to try and fix this problem. I have 2 x Windows 10 on my PC, 1 OS works and one doesn't.

The failing one will not repair, no restore points, Have tried SFC scannow, CHkdsk, DISM commands and fixmbr, fix boot commands etc, tried reparing the image from a downloaded iso in CMD and RE. Really at a loss now as what to do

Nothing seems to work but from my other OS i can still access my files perfectly fine - Answers to the quesitons:

· OS - Windows 10 64 bit
· What was original installed OS on system - Windows 7
· Full retail version - Received from University on Microsoft Program (Cannot remember exact name of it now)
· Age of system Approx 5 years
· Age of OS installation - have you re-installed the OS - Yes, about 1 year ago ish?

· CPU - i7 980x
· Video Card - 2 x Radeon R290
· MotherBoard - Asus Rampage 3 Extreme
· Power Supply - XFX 1200W

· System Manufacturer - Custom Built Machine

· Laptop or Desktop? - Desktop#

Thank you in advance for any help I receive

Edit - Just to add when the problem first came up, it just came up with a Windows 10 Blue screen saying File missing windows\sdystem32\drivers\EHStoRtCGdRV with an error code of 0xc0000102 but since trying all said methoids above this screen does not come up anymore. When booting, it just goes into automatic startup repair mode and will always follow with a "Your system cannot be repaired" type box asking me to "Restart" or "Advanced options" - where you get restore, cmd prompt etc - Hope this helps

Create a batch file to automatically reboot to a dual boot option

Hi,

How to Quickly Boot Between Dual OS Windows 10 and Windows 7 or 8.1


There are instructions beginning with Step 2 on locating Windows 10 identifiers.

 

KB3140743 will not install

Here's how I got kb3140743 to install. If you dual boot, triple boot, etc., this may help.

First, I triple boot OS X, Linux and Win 10 using cloverEFI boot loader. Whenever this failed update loop occurs, the solution is the always the same for me. My EFI partition is marked as active because that is where Clover resides so:::

1) boot into windows 10

2) launch disk management

3) set Win 10 as active

4) recheck, download & start the update

5) reboot when asked

Once complete, I boot from my USB boot drive and set EFI back to active.

Good Luck & I hope this helps you!

 

Same issue with me for the most part, I am also unable to boot into safe mode, unable to auto repair. I CAN enter command prompt and use "DOS" to see all the directories and associated files.

A quick possible solution, download a Win10PE from this post, and use the fix boot option in Macrium which you may find in 'restore' tab.

 

Apologies to waste your time but I have reformatted as I lost my patience with the machine - Appreciate the time you've given
