Dual Boot Windows 10 - EasyCD Boots to Missing Drive

I deleted the EasyCD menu choice from a drive that is no longer connected, then told the system to skip the menu. Now the computer will not boot or allow repair in advanced options.
I bought a new computer for my wife that had a Win 10 HD, so added the HD from her old system as a second drive with all her programs and data intact. I set the default menu to her HD, but installed the EasyCD program where it now cannot be found. System BIOS has resisted attempts to boot from USB, but did manage to get it to run a Windows install disk from CD. The repair options pertain only to the absent drive.
This is a HD with 40 GB of data and a number of apps so would be useful to be able to bypass the missing menu, or enable the bootmanager to ignore all the references and use what was a working Win 10 setup.
Am I doomed to wipe this drive and reinstall, or is there some magic that could be applied if I work on it as an external drive where I could edit files to restore its bootability.
Sorry for the confusion, as starting from scratch may make for more work.
Thanks for any advice.
 
If you had a PC with two different versions of Windows, the newer installed on a PC with the older version already present, the automatic MS dual-boot process will have added an entry for the new OS to the BCD of the older where it's already located and update the boot files on the old system to the newer level.
If you subsequently decide to remove the old OS, you'll see from the above that you'll also be removing the boot files of the new OS and rendering it unbootable.
If you remove entries from the BCD leaving only one, you don't need to "skip boot menu". Windows boot manager won't present a menu if there's no choice to be made.
If you have the installation DVD of the affected OS or you made a repair disc (Control Panel > Backup&Restore > Create repair disc) put either into your optical drive
Boot the PC > "Repair Your computer" > "Repair Startup"
Do the whole of the above line three times (many things to fix, only one done per pass)

You can create a W10 repair disc by following the above using your wife's PC, then try it on your PC if neither of the above is available.
