Duplicate Windows 10
Duplicate Windows 10
Ok, I'm probably missing something obvious here! I have successfully installed Win 10 on the M2 drive of my PC and it works fine. I want to create a copy onto a second drive (SSD) so that I always have one good bootable copy if I mess things up. I have copied the data partition across to the second drive but I can't see how to make a working entry into the Boot Menu. I have pointed the new entry to the EFI partition but how do I create an entry into the EFI that points to the new drive? The initial Boot Menu entry points to EFI\Microsoft.001\BOOT\bootmgfw.efi but if I just make the new menu entry point to this file as well, then it just boots up on the existing M2 drive. The annoying thing is, that I had this working ok before but now I have changed the hard drive, I can't see how to do it. Any help appreciated.

Dave,
The easy way to copy a Windows OS is the use "Copy" and "Paste" in Partition Work and put a tick in "Add to Boot Menu". The OS is copied to Free Space and a Boot Item is created. Nothing more to do.
You can either delete your copy and use the above method or let us help you create a Boot Item for your current copied OS.

Thanks Brian. I thought I remembered that was the way to do it but when I tried, it made the copy but gave an error message at the end saying it couldn't add it to the Boot Menu, therefor I thought I must have remembered wrong and was trying to do it manually.
I have now solved the problem. After reading another post about using TBOSD to edit the EFI partition files to create a second entry, I discovered that the EFI partition was full, preventing the automatic process from writing to it. I freed up space by deleting a number of old entries with TBOSD that were no longer in use and then the automatic 'Add to Boot menu' option worked fine.
Thanks for your help.

Dave, thanks for the feedback. What is the size of your ESP? The default size of the ESP after a BIU install to a blank disk is 400 MiB. This size allows lots of multi-booting.
Re: Duplicate Windows 10
Mmmm, mine is only 99 MB.
The M2 drive is 250 GB; 233 GB formatted and partitioned. There is a Recovery partition of 499 MB, EFI partition of 99 MB, an OEM partition of 827 MB (not sure what this one is?) and the main Boot/Primary partition of 231 GB

I'd resize it to 400 MiB. Easy to do with BIU.

Thanks Brian. Yes I'll do that
