I've spent my whole sunday afternoon with this and I'm stuck. I've had an XP on a disk(Drive "C", 60GB IDE), then I bought another disk(Drive "F", 500GB SATA). After that I installed Windows 7 32bit on the new disk. The problem starts when I want to remove the old disk from the system, because it just doesn't boot from "F", when it's all alone. The same problem occurs when I change the disk priority in BIOS: only loads 7 when both disks are in the computer and the old one is the first in BIOS.(Not the boot priority, but something about priority among disk drives...). When I open the computer management it regards the old disk as system partition, the new one as boot. Both disks have one primary NTFS partitions, active. Also I can't change the drive letter of "F" to "C"(after old "C" is renamed), because it says: "The parameter is incorrect.".
I could've done something wrong during the installation but I don't remember that I asked Windows to split between the two drives...
I've tried to disconnect the old disk, then reboot from the recovery disk but it didn't find any errors and didn't solve the problem either. I've tried to move the boot manager to the new disk(however I'm not sure it's on the wrong disk). Like this: Moving Boot manager to Different Drive
It didn't help at all.
I really don't want to reinstall the OS so any idea would be welcome.
Thanks for reading
