Infact my system was working fine and when I restarted after an hour or two, It gave me an error “Reboot and select proper boot device or insert boot media in selected boot device and press a key”. I had no idea what to do and how to fix. So I kept my system aside thought of submitting to repair centre. And today I got your blog. Finally got it fixed. St+G21ellar software also worked perfectly fine. Though it was time taking but it was worth. Thanks Mansi.
