I have swapped two hdd recently on my pc, including cloning the os on to slightly bigger hdd. It all works fine, but after using a jumper on the clear cmos pins to restart it as it came up with a message "LDR missing". Before i cloned the os and now that i have, i couldnt access the bios. The only way i have been able to get my pc working again is by clearing the cmos. But how do I regain access to bios as i would like to change some settings?I am using an asrock mobo and the key to access bios is f2, it looks kinda like the keyboard? Any help would be of great assistance thanks Adam.
