Due to work related reasons I had to install Ubuntu 16.04 LTS on my computer. I have an SSD with Windows 7 and decided to buy a 1TB HDD and partition it to install Ubuntu on it and leave some space for my larger windows files. I followed the Ubuntu installation tutorial on the ubuntu official site and at first everything was ok.
Then, the first problem with Ubuntu arose: the Wifi connection was incredibly slow while on windows it was normal. I read that this was some kind of bug from Ubuntu so apparently there was nothing to do.
The next day I realised it took much ( much) longer than usual to boot on Windows 7, - it approximately takes less than 1 minute and it took almost 7 minutes-. Once logged in I also realised Windows 7 took much longer to open files and programs. What's more, when I tried to copy files(write) into the free allocated space I left on the HDD, the copy menu didn't even show up. I couldn't even copy files on my SSD!
As soon as I reformatted the HDD ( hence removing Ubuntu) my system worked as normal. I repartitioned the HDD to leave space for files but haven´t installed Ubuntu and there hasn't been any problems.
However, I still need Ubuntu and I don't want to try to install it again like last time and work me up trying to figure out what is wrong with it. So I hope someone could shed some light on this matter and every bit of help is truly appreciated.
PS: I find worth mentioning that I have previously searched the Internet for the answers to these problems but nothing was helpful
Thank you!
