I have a Lenovo G560 0679 series laptop, which i believe is a 64 bit system. Few months ago, my comp shown some blue screen and gave me boot up issues. My friend has been able to help me fix it a few times (he said he simply just let start up repair do its own thing). however, this time, he is away and is unable to help me. So I try to do the same thing, I run start up repair, and it says problems can't be solved automatically, I clicked on details, it shows that a problem signature is CorruptFile.
This time, theres no BSOD, but it kept leading me to the Start up recovery page (the one with sys restore, restore system using image etc and command prompt). I tried running safe mode, as well as safe mode with networking, last known good config, ran all the options on system recovery/system restore. It seems like the only option i have left is use the command prompt to fix the problem. I lost the windows installation CD, so some of the commands such as bootrec.exe is in vain. I don't really know what i'm doing any way when I use the command prompt.
As a last resort, I'm willing to reinstall my comp, what do i do so that i can save some files? also is it possible that I download the reinstallation file since I lost the original one?
Please help me out if you can, and let me know if you have any questions or need to know more info.
