No Bootable Device Found after wrong selection in MSConfig

Question

I think I have made an incorrect boot up selection in MSConfig while trying to fix a shutdown error.

I changed Selective Start-up to Normal Boot. Now I get a message saying "No Bootable Device Found, Boot from install disk and select Repair My PC". I tried that but can't see how to proceed.

How can I correct this?

Answer 1

Thanks for the suggestions, I tried all to no avail. Eventually, I managed to fit it, here's what I did:

Using Parted Magic I concluded there was no damage to the System or EFI partitions. Searching the error code (0xc000000e) produced many irrelevant "fixes" but the one of the many from Easeus looked promising, www.easeus.com/partition-manager-software/fix-uefi-boot-in-windows-10-8-7.html#3

Go to Method 2. Parts 1 & 2 went perfectly but the commands in Part 3 just gave errors. So before you start Part 3 Exit from DISKPART The "cd" and "bootrec" commands require the command prompt.

After this my system booted without issue.

Hi RIck. I'm Greg, an Independent Advisor.

Hopefully System Restore from the Repair Mode or bootable media will undo the msconfig fatal setting, if not we'll delve deeper. If you can post a picture of a bootable partition manager drive map with all listings showing I can tell better what you did. If you installed to the SSD with the HDD still plugged in then it configured a Dual Boot with the boot files remaining on the HDD and SSD is not independently bootable - this is not correct and will make it harder to repair since you want to target repairs to the SSD and it should be plugged in alone during any install or repairs to be correct and effective.

Use whichever method works in this link to get into Repair Mode so you can do the necessary repairs or do a Reset: https://translate.google.com/translate?sl=auto&...

Easiest is to force shutdown by holding in the power button twice until it starts into Repair Mode. Once in the Repair Mode try the numbered steps below.

It may be necessary to create bootable media on another PC to access Advanced Startup Options to try repairs, a Reset or do the Clean install. The bootable media has it's own set of files so that repairs or Reset might work better, doesn't require a password, and you'll have it to if necessary do the vastly superior Clean Install.

To create Windows 10 Installation Media on another PC install Media Creation Tool and follow the directions here: http://windows.microsoft.com/pl-pl/windows-10/m.... Uncheck the box for Recommended Settings to choose the exact version and bit rate for the target PC only.

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key given here: https://translate.google.com/translate?sl=auto&...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

Choose the boot device as a UEFI device if offered, on second screen choose Repair Your Computer, then Advanced Troubleshoot Options, then:

1. Try a System Restore,
2. If that fails try Uninstall Updates as far back as necessary to see if this was caused by an Update,
3. Open the Command Prompt to:

a) run System File Checker: https://translate.google.com/translate?sl=auto&...

b) run a full Disk Check: https://translate.google.com/translate?sl=auto&...

c) trigger Safe Mode with Networking (for internet) or Safe Mode following https://translate.google.com/translate?sl=auto&... to roll back Updates & Drivers in Windows Update History, update your drivers from the PC/Motherboard manufacturer's website and diagnose further:

https://translate.google.com/translate?sl=auto&...

4. If those fail then go back to Troubleshoot Options to do a Reset.
5. If that fails back out and unplug the HDD, boot into media, choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, click Next to let it create needed partitions and start install - this makes it foolproof. Everything needed to get the best possible Clean Install is here: https://translate.google.com/translate?sl=auto&.... It is a better install than any amount of money can buy and a great learning experience that will make you the master of your PC because you will learn what works best and how to apply it with your own hands.
6. If you have files that aren't backed up you can use the same bootable media to try to rescue your files using these methods: https://translate.google.com/translate?sl=auto&...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Windows is not bootable, so I can't enter any modes. The EFI boot partition and the System partition on Disk 0 both test OK using Parted Magic (FSCK)

Disk 0 is a newly installed SSD a week ago, upgraded to 21H1 today. I still have the original HDD (20H2) intact so last resort is "back to square one" but I was hoping I could undo the damage done by MSConfig.

The original disk (HDD) configuration was MBR, booting from the C:\ partition. The SSD has been converted to GPT. I can't remember whether the boot partition was converted to the EFI or was still the C:\ partition. I was intending to make the machine dual boot WIN/Linux and also VM, however Gparted now shows the EFI partition with a Boot/esp flag. I don't konw if MSConfig is capable of making this change or whether I had already done it after the MBR2GPT transition. I had to make major changes to the partitions to facilitate the MBR2GPT and in preparation for dual boot.

I was intending to build a recovery partition next. Should have done that before fixing the shutdown problem - if it ain't broke, don't fix it!!!

Is it possible to trick the system to boot from C:\ , then run MSConfig and undo the change? I have a WinRE disk, could this help?

Try entering Safe Mode to repair Windows.

Check this link in the Option (From a black or black screen)

If you can't restore Windows after performing the previous steps.

I recommend you borrow a PC to create a USB to repair Windows
