Thanks for reading.

Regarding my Macbook Pro 2013 that had 256GB SSD which is a dual boot Catalina and Windows 10.

The Mac partition was just one partition and the Windows 10 had two partitions, the OS and the second one had all my work on it.

I needed to upgrade the SSD to 512GB.

In Windows using EaseUS ToDo Backup I backed up the full SSD as one backup (contains all partitions related the the Mac) and then also separately another backup that was just the Windows partition.

- Installed the new SSD
- Installed Big Sur
- Ran the Boot Manager app
- Installed Windows

That all went fine, however of course I now needed to Restore everything.

- Booted into Windows
- Installed EaseUS ToDo backup
- Proceeded to Restore the full drive from my full backup that I have on a separate drive.

EaseUS seemed to handle the Restore Ok, it allowed me to select everything (the backup that had both the MacOSX stuff and the Windows 10 stuff)
It restored a bit, then needed to reboot into Efi and continue restoring like that.

All looked good.

However now all get is the Macbook booting directly into Windows 10.

If I hold Option on the machine starting up, all I see is a single drive that says EFI (as opposed to seeing MacOXS and Windows) and that then takes me into Windows 10 again.

I cannot seen to get the Mac drive to appear at boot time. ?

Looking at the drive using a disk manager via Windows it looks like the MacOSX stuff is there, but I just cannot boot into it.

Any help would be appreciated.

Thanks
