The last time I installed Windows 7, the boot manager automatically got installed in a small hidden partition, and the main os into another partition. So, formatting the C: won't affect the boot manager.
Yesterday I wiped and repartitioned my HDD like this:
- 50 MB primary NTFS (meant for boot manager)
- 100 GB primary NTFS (for Windows 8)
- 50 GB primary NTFS (for Windows 7)
- Some logical partitions to install Ubuntu and other OS
I installed Windows 7 and then Windows 8, and now there is no OS choosing menu. System directly boots Windows 8 and the 50 MB partition is empty.
There is a way to boot Windows 7 and even Ubuntu directly from the Windows boot manager with EasyBCD. But How do I put the boot manager in the 50 MB partition?
