Removing old IDE HD causes boot failure

[kyk]

Hi guys,
First off, specs: Gigabyte GA-SME-S2
AMD X2 2.2GHz
Corsair 430CV PSU
500Gb Seagate SATA Hard drive
40Gb Samsung IDE Hard drive

So I've just upgraded to Windows 7 from XP, and I want to remove the old 40Gb IDE hard drive mentioned above to free up its PSU connector. Trouble is, when I take it out and try to boot up I get a Boot Disk Not Found message. I installed Win7 onto the larger SATA hard drive (which I believe was also the one on which XP was installed previously), yet the system won't boot up without the IDE drive. How come? Any ideas would be greatly appreciated

i had this problem before its a setting in the bios that tells it the boot device is an IDE drive and not a SATA drive i believe there would be a setting to set it to AUTO as well . if you still have it check the manual for you mobo or just explore the BIOS

Thanks for the help buddy! Trouble is, the SATA drive doesn't show up in BIOS, only the IDE and my DVD drive (also IDE). Any way I can get the SATA drive to be recognized by BIOS?
