This unfortunately didn't work for me on Win7.
I just made a new Sierra install on a seperate SSD, and am now trying to boot Win7 and Win10 with it via Clover.
Win10 boots with the trick mentioned above, but Win7 isnt been seen by Clover, don't know why. Both disks are MBR.
Later i converted win7 MBR disk to GPT using AOMEI partition assistent, which creates an EFI partition on the disk. Now both Windows disks are beeing seen by clover (now GPT & MBR). But i get an error when trying to boot Win7. After trying some times booting via Clover, Win7 sometimes starts, but sometimes gives me an strange error.
Is it best to also convert the Win10 disk to GPT via AOMEI Partition Assistent?
Or should i make a new install of Sierra using UEFI instead of Legacy version of Clover?
Thanks in advance.
