Hello, recently I got my friend over to install Halo Reach to my Hard Drive as mine was laser burned from a old model of xbox. That was my old one that was the older model and I had let my nethew use it and he laser burned it. Anyway, I play Halo Reach for about 1 hour then changed game to Fifa 12 and played for 30 Mins. After this I turned my Xbox off in the normal way. The next day, I turned on my Xbox and Fifa was not being read. I changed the game to see if it was problem with the game but no, it was with the Xbox. This was weird as the I have not had any major problems with my Xbox's and the only reason I changed from Xbox 360 to slim is for the looks and less chance of breaking. I stopped and waited a day. When I came bake to my Xbox, the first thing was saying that I needed a Kinect update and needed to sign in. Then as I took of the message, the screen had a page saying to Create a new profile, recover a profile or skip.I skipped and checked my hard drive to see if my profile had gone corrupt but when I got to the Memory settings, the hard drive was not appering. This was also weird as I have never had these two problems and never had two problems at once. What are they?, do they need a repair from a shop or is there a home fix? and if so, how much?
