The other problem : AHCI unbootable

[Manish Jain]

Hi,

While installing FreeBSD 10.3 amd64, I tried switching from IDE to AHCI 
in my BIOS's boot configuration. But when I do this, the installer 
installs the OS on the hard disk, and then the system is unbootable - 
the BIOS screen hangs with the message : boot record missing.

Can anyone please tell me what might be the problem ?

Regards
