Feature update to Windows 10, version 1709 fails to install

1. if you mean i do

BCDEdit -enum {FWBootMGR}

and i can see parameter is incorrect at the bottom. YES its still there.

2. link of BCD backup

It isn't really that hard to do. I suggest (as I think Robert implied) first try should really be BootRec. It isn't as drastic. But that must be done in the Recovery Environment (the BCD won't delete while booted to Windows) where you refuse to go. However, you can get there an easier way. Shift+Restart will go to the one that is on the SSD. But that probably/possibly becomes impossible, if somehow the BCD is destroyed. That is why really you need still to be able to get to the Recovery Environment of external media.

If you upload your "C:\BU\BCD Backup", I'll be able to fiddle with it. Does it still say "the parameter is incorrect" when listed?

i am just in awe on what i have read. None of which makes senses to me. (lol)

Regarding the Easus article...

(1) I didn't have to turn off Secure Boot  for either BootRec or BCDBoot.

(2) /FixMBR & /Fixboot are for MBR type HDDs - but are likely harmless on GPT.

(3) /RebuildBCD will only look for additional, compatible Windows installations to add to the BCD - unless the BCD is renamed/deleted first. Then, it generates a whole new BCD. (I guess one could delete just the existing Boot Loader entry in the BCD, then it would be recreated.)...

X:\windows\system32>bootrec /?

Repairs critical disk structures. The following commands are supported:

/FixMbr -- writes the master boot record of the system partition using the master boot record compatible with Windows. This operation does not overwrite the existing partition table.

/FixBoot -- write a new boot sector onto the system partition using the boot sector compatible with Windows.

/ScanOs -- scan all disks for installations compatible with Windows and display the entries that are currently not in the boot configuration store.

/RebuildBcd -- scan all disks for installations compatible with Windows and allow the user to choose which to add to the boot configuration store.

(4) I'm not a fan of "/f ALL" in BootRec, unless maybe making a DVD. (But it didn't really hurt.)

(5) Where the Easus article says...

"diskpart will now show the full list of volumes on your PC, find UEFI volume from the list: UEFI partition will be on Volume 2."

That wouldn't always be true. Mine is Volume 3, but turns out to be Partition 2...

I've done both of those now. Neither killed me. Here is what I think I know...

(1) BootRec exists only at the Command Prompt of the Recovery Environment. It only affects the BCD itself, (which makes it safer, actually). To get a clean BCD - first backup, then delete/rename the current one. Renaming provides a second backup. That's what I did back then. Otherwise, it will merely search all drives & add any compatible Windows installation to the BCD - if it isn't already there. Here is what it produced for me (a year/more ago) before a reboot...

X:\windows\system32>bcdedit /enum

It did not turn off the recovery partition. That got set up. But I wonder, where was "resumeobject"? But I never noticed a problem with Sleep/Hibernation that I can recall.

(2) BCDBoot exists in the Command Prompt of a booted Windows. It will not only do the BCD, but also all the boot files that are on the EFI (system) partition will be replaced. That includes the boot loader, itself. Well, I can't swear my UEFI files were replaced, because a DIR before/after shows them all to be identical. But they were mentioned in the verbose report (/v) I posted above (I think). In addition, it gave me a full set of MBR boot files, which soon I did delete. I suggest one check whether the HDD is GPT or MBR , & run with the appropriate option (UEFI or BIOS - not All).

Regarding the BCD - I wish I had deleted it first. I didn't, & BCDBoot left most junk intact, like a couple of entries that reference my empty v.1703 Recovery Partition, but are themselves unreferenced. (Soon, I'll just delete them.) But it did delete a Windows Setup entry. I wonder, had I used the /c option - would that have been as good as deleting the BCD?

It did seem to do work on the Windows Boot Loader entry - that may be fresh. But it removed the references in it to the v.1709 Recovery Partition. Therefore, a Shift+Reboot did not go there, but just did a reboot to Windows. I needed to run ReagentC to turn that back ON.

Here is what BCDBoot produced (after reboot)...
