How to fix boot for windows 7 when bcdboot says "failure to copy boot"

I decided to install win 10 on my new nvme ssd card (again) and since it was a new drive to dual boot I basically had to keep switching drives to boot from the bios which was a pain.


My old win 7 which also had win10 on the drive (different partition) used GRUB to boot but in a rush I think I accidentally deleted it which means that GRUB boot no longer exists.



So I decided to use EasyBCD on the NVME Win10 which seemed to only work with the other win10. So basically, I have two working win10s and one broken boot of win7.


And now BCDBoot won't copy it "failure to copy boot files". So I'm wondering how do i fix this so I can boot into Win7?

Can you post a screenshot from disk manager showing all the details so we can see if its gpt disk and uefi

Here we go. The drive that's in question.

G is the one with win 7. The other win10 boots fine but it's not the one I"m currently on.

I can't see that and it doesn't have all the details needed at the top

The c drive is uefi so you need to edit the uefi loader YouTube

And it's

bcdboot G:\Windows

you attempted as an administrator?

Yes, I was actually in the the system recovery mode when I tried that. And at the time it was D:\windows and that's where it failed

Does that fix my Win7? Cos I can boot into the C drive just fine.

You could probably use

# bootice to fix master and partition boot sectors to be in line with your OS you want to boot from each individual partition

# EasyBCD to design your boot menu per your gusto
