I have an HP Envy laptop with windows 8. I have a windows 8.1 full install disc. My laptop will not boot from the dvd drive even though I set the correct boot order. I have also disabled secure boot and enabled legacy devices. I was messing around with the disk volumes and think that I erased the partition with the original OS. I now get a hard disk 301 error and it says to install and OS. Iike I said before, I do have a windows 8.1 full installation disk, it just wont boot to it. Any Ideas would be greatly appreciated. Thank you1
