Doesn't boot when connect 2nd hdd

[sachchundan]

secondary hard drive, a Seagate hard drive has been working perfectly. But one day when I tur onq I have tried entering the BIOS to change the boot order but if the secondary hard drive is plugged into a SATA port at all my computer will do nothing and stay on the BIOS splash screen regardless of how much I mash F11. I have tried entering the BIOS with the secondary hard drive unplugged to try to change the boot order but it doesn't show up at all, also tried plugging it into different SATA ports but no luck. I managed to hot plug the secondary hard drive while windows was loading which worked, so I need to get my data from secondary hdd
Please help

sachchundan, are you able to get your data off once you plugged the drive in while Windows was booting? Best to get in touch with support in this case. Best of luck.
