I have a new ASUS T-300CHI 2 in 1, purchased in April. I purchased this to be used as a 'tool'...in the past 6 to 7 weeks it has accomplished just about everything I wanted it to do and performs well...with the exception of Windows 10. I made at least three, possibly 4 mistakes so far...removing windows 8.1; loading windows 10, and then deleting 8.1 .old from the files. Using Windows 10 for the first 4 days proved to be crap. I removed 'my files' and attempted to load Windows 7...Boot Manager went crazy on me and is still popping up at times when I re-boot or even start up. I went to a shop, they cleaned up my mistakes and told me I had to use Windows 10...I'm stuck with it. Personally, I don't care how but I want to get rid of windows 10...for ever! I have a HP unit running on windows 7 now (again) after loading windows 10 and having a true night mare with it...I'll never load 10 on it again. I don't care right now if it is a hack, or not...I only use Windows Professional Word, Excel, PowerPoint and Publisher. I do not like Edge, One Note or any other of their apps. But, I'm stuck with a couple programs that use 'MS' and need the OS... Can I get a copy of windows 8.1 and remove windows 10 from this unit? Can I some how load windows 7 64 bit on this?
