I installed freebsd with dual-booting. I specified an empty partition for freebsd auto-configuring.

After it was installed, windows boot manager disappeared.

What's going on? Should I recover it, or install an alternative boot manager?

by the way, what is UEFI and GPT? is that matter?

Did you install any boot manager (grub, lilo, etc)? – Peter Feb 8 '13 at 8:55
I tried boot0cfg, but in pain. then I tried to install grub2 from fedora but it cannot read bsd disk. – snow Feb 8 '13 at 15:00
What kind of filesystems are you using on Windows and FreeBSD? grub should be able to boot FreeBSD UFS disks (i am using Debian and Ubuntu's grub). – arved Apr 28 '13 at 10:36
Work to enable FreeBSD to boot from UEFI is ongoing but not integrated into a release yet. Current FreeBSD releases cannot boot from UEFI. – Roland Smith Oct 19 '13 at 22:19
