Windows 10: Laptop cannot boot without USB stick

Split from this thread. Thank you for these!As my laptop cannot boot up unless i insert usb, the only options i have to fix this would be using BIOS or physically check if the hard disk is connected properly. As I am not really tech savvy, I am afraid that if i try to dismantle the laptop to remove the hard disk, i might screw up. So, I would prefer to use the BIOS method.
