yes, there's nothing to recover, it's MBR problem or something related to bcd, so i don't think i need foremost, and i'm afraid to go for the first solution given by Avtvav, because some people say:
Using a System Repair disc on a different PC than one it was created on isn't recommended. These discs contain device drivers and other files specific to the system, so unless your source and target PCs are similar (same) in terms of hardware, you might end up causing even more problems.
I'm searching for a safe solution, i already have one, downloading a
windows iso boot it up, and use the repair option. But I'm not going to download 3 gb to fix a silly problem like mine.
I'm not going to give my laptop to the computer store next door, they don't know anything about computers, you give them a computer, they fornat it. That's not an option. I'm not going to buy a windows cd, waste of money to fix a silly problem. I'll try to borrow one from and
fix it, But the best option is to find a small tool that i can burn to a disc like super grub disk for example which fixes grub issues, i hope to find a similar tool to fix bcd and mbr issues, i didn't find anything yet.
