I have a computer with several hard drives, one Windows 7 install and one CentOS install. I moved the computer to a new case and now the BIOS only recognizes one of the disks as bootable, and that disk boots to grub. I am fairly certain Windows and CentOS are installed on totally separate disks. I've tried only connecting one hard disk at a time, but the BIOS only recognizes one particular disk as bootable and can only boot that disk into grub. All the other disks are not recognized as bootable. Has anyone seen this behavior before? Any advice on how to approach the problem?
