hey everyone, ive got a windows 8 laptop (asus n550jv) and recently it was behaving a bit slow even though its got an i7 (everything was quite slow, and i ran performance test and literally everything was about 3x slower than before. cpu from about 8000 to 3600, so i thought wtf is going on here). i decided it was going slow because of the windows 8.1 update and i thought "lets just put windows 7 on it. it works with everything and is the easiest option." well after reading loads of articles and finally getting my 7 cd to boot i got a gpt error or something. i decided the error would be fixed if i formatted the drive my os was on. it didnt fix it. so i decided to get a windows 8 disc and install that, and that worked well. it was a windows 8 pro upgrade disc but sadly i got normal windows 8 and not windows 8 pro. but at least it automatically activated. anyway sorry for all that probably unneeded information. anyway now when i boot my pc (or i think it might only be when i restart, not 100% sure) im given 2 options for os's to boot: "windows 8 (on volume 4)" or "windows 8". the "windows 8 (on volume 4)" is the one which works. the "windows 8" one just attempts to repair the computer and fails (theres no os...). how do i delete that one? also might i note my friend told me i should also delete the partition with the os on after i format it and then partition it again. could that effect it? its not a major thing, but just a bit annoying when i boot my pc and have to click on windows 8 for it to boot. anyway if anyone can help id be grateful. thanks.
