I know my questions looks similar to others, but they have not been answered as to solve my problem. I'm from Mexico. I got an ASUS S451L. I got the computer with windows 8 then I upgraded it with windows 10. A week ago I got a virus and lost all my data, so I decided to install Ubuntu 16.04, because I read good reviews about it. I was very excited, but after I installed. I tried to get my favorites videogames (LoL;GuildofWars2) running but they wouldn't work on Linux. Yes, I installed Wine and play on Linux. I had to installed Ubuntu again because after trying to install GW2, it crashed.
I got tired and decided to go back to windows. Unfortunately, I never backed up windows; I was afraid I deleted forever, so people told me to buy a new license or get it pirate. But somehow , reading forum, I got to know if I still had the ISO. the only problem was that I couldn't boot it. GRUB would get on the way. Anyways, I repaired the boot loader using that Ubuntu application Boot-repair. I got to the command thing where I can type bootrec /Fixboot or /Fixmbr. It told me that the processes were succesful. But it was still booting GRUB. I prioritize Windows Boot manager (yes , it gave me theoption) but it wouldn't boot it. I uninstalled UBUNTU hoping it would stop booting GRUB, but it was still booting (in a blackscreen with inframes thing). In conclusion, it is not booting windows and evennthough I got a Windows 8.1 PRO iso, it sends me an error of compatibility:
"The computer started using Windows Installation media. Remove the installation media and restart your computer so that Windows starts normally. Then, insert the installation media and restart the upgrade. [DO not select !custom [advanced] to perform an upgrade. !custom advance installs a new copy of Windows and deletes your programs and settings/" I read something that said this happened because it read the booter my computer has as default. I have my key license. I just need to boot Windows 8 so I can install it. Is it possible? What could I do? Am I doomed? Will Yuri ever marry Victor? HELP ME !!
P.S. sorry for the long post. P.S.2 I don't know anything about programming or those things in case you didn't notice. P.S.3 I tried the DISKPART thing but it didn't do anything when I typed the coomand "ren bcd bcd.bak".
