You could try and repair Grub. Look Here: https://sites.google.com/site/easylinuxtipsproject/grub

Re: Boot manager missing

Did you format the new disk for Win7 through Windows?
Did you get utilities with the disk?

Re: Boot manager missing

Is this an error from BIOS or UEFI?

Some BIOS systems will not boot without a boot flag on a primary partition which Windows has to have, but grub does not use. I usually suggest a boot flag on a primary partition even with Linux only installs just to avoid the issue with some BIOS.

If UEFI then it has to have an efi partition as the first partition.

Post this:

sudo fdisk -lu
and/or this if fdisk says gpt
sudo parted /dev/sda unit s print

I think it is safe to assume it is BIOS, as it has 99.9% of the market.

Anyway, if you are looking to run Windows and any distro of linux, it is easiest to install Windows first THEN linux. Ubuntu's Grub (not sure what Mint uses) is MUCH smarter than Window's 7 boot manager.
