Not Finding Second Internal Drive

Hello,
I recently installed rEFInd on my macbook pro, and I noticed that it did not find any bootable partitions on my second internal hard drive. However, if I hold option while booting, and then select EFI Boot which brings up rEFInd, it finds the partition.
Any ideas?
This is probably a drive-detection timeout issue in the firmware. Try pressing the Esc key after rEFInd starts and see if the drive appears at that point. I'm considering adding a configurable delay and re-scan upon startup to help work around this problem. (One or two other users have reported having this problem.)
Thanks for the reply! I have another problem now. When I have a bootable USB thumb drive plugged in and try booting from it from rEFInd, it just starts booting my Windows partition. The icon in rEFInd is called "Legacy OS"
Did pressing Esc work to solve your first problem? If so, please check rEFInd 0.4.6. I've added the scan_delay parameter to add a delay to the OS scan, but as I don't have this problem myself, I need people to test it, and would appreciate a report from you on whether it works.
Concerning your new problem, I'm not sure offhand why it's doing that, but I have seen numerous reports that some Macs are unreliable about booting legacy (BIOS-based) OSes from USB media. Are you able to boot using the Mac firmware's own boot selector (accessed by pressing the Option key during system startup)? If not, then I doubt if there's anything I could do to fix it. If you can, I might be able to find a workaround, but I'll need more information from you, including output from a debug version of the program that I'll need to prepare, so you should send me private e-mail about this.
