This thing works like charm man. Thanks a lot. Although boot entry in UEFI/BIOS is still named as Ubuntu, anyway to change that ?
a) My secure boot was never on the first place. Actually 2 years back when i actualy started using linux(ubuntu) my wifif couldn't work due to some reasons and solving that it required secure boot to be off and since then i never i turned it in UEFI/BIOS.
b) I wasnt' comforatble with that hd2 and hd1 stuff and as i could boot into Manjaro i never follow that link
Yes my laptop does comes with preinstalled windows 10 which i rarely use thoguh.. Its just heck lot of time to waste for me to setup coding environment there and then deal with random errors.
