Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

Cannot sign in microsoft account.

My device: Lumia 520. GDR2.
I cannot sign in my Microsoft account on my device. It didnt say any error but Microsoft account is not listed in Email and account list. When I click add button, it will show microsoft account option but after press sign in, it is still not shown in email
and account. Another problem is i cannot delete facebook account. Error code: 0x83cf1202. I have tried as suggested here: http://support.microsoft.com/kb/2475837/en-us#step0x83cf1202 but as my Microsoft account is not shown, I cannot do step 6.

Any suggestion?

My teredo tunneling adapter is non-existant on my pc, I´ve tried adding it by legacy hardware but it wasn´t there, I've set DisabledComponents to 0, it doesn´t show up when i view hidden devices and there´s no download for this driver apparently, I´ve
tried a lot of solutions and nothing has worked for me.
