Windows 7: [HELP] error code0xc0000225

hello all my friends



I want to ask about the case of my dual boot
I have OS win 7 home premium, I made a partition unlocated by taking a partition of C: a 400GB for about 10 gb .. and i use that 10 gb partition for linux .. so, there are C , D, and unlocated partitions

I started to install ubuntu .. sda 1-4 was read at there and they full at all but there is no unlocated partition .. I am confused .. when my boss asked to install Ubuntu quickly .. in ubuntu partition sda 1 was unknown, sda 2 and 3 were NTFS and sda4 was FAT32 .. so I used sda4 for install ubuntu (without creating a partition for the swap) and successfully installed ubuntu ..

when I came back to win 7 then blue screen while booting .. I think most of the data in Windows 7 overwritten by linux .. I read the error code was 0xc0000225 - Because the boot selection failed a required device is inaccessible .. I recoveri and it has failed, its OS is unread ..
I tried to enter safe mode .. but still blue screen

I tried to login ubuntu again .. and then win 7 file overlap by ubuntu ..

anyone can help find a solution without reinstall

thanks before
(sorry if my english language not good )
