I built a computer with Win7 at the end of last year and everything has always worked fine. 2500k, 560ti, 8 gigs Gskill. A couple of weeks ago I bought a second HDD and installed Linux Mint Cinnamon on it. Again, everything was fine. I could switch between the two OSs no problem, games worked, virtual machines, any kind of taxing stuff. I moved this weekend and I was super careful with my computer but when I hooked it up at the new place, Windows was no longer able to boot. The Linux boot loader was still there and I was able to get into Mint (which seemed to be working). Also, Mint automatically mounts the Windows HDD and I was able to browse the filesystem so at least the Windows HDD seems to be working. I tried booting from the OS disc and running some of the repair tools. Some seemed to detect the OS (unless they were detecting the Linux OS) and others didn't. I ran bootrec.exe and tried to fix the boot sector and MBR but it didn't help and unfortunately I think I made Mint inaccessible (probably lost the pointer to the boot loader though I'm not clear on how this works). I'm not sure where to go from here. I was hoping that by putting the Linux OS disc in I could maybe access the existing installation (maybe recreate the boot loader, I don't know). Then for Windows I don't know. I think I'll have to reinstall but at least if I can get Linux up again I can back up my Windows files. I would like to know what happened that suddenly damaged the Windows OS. Could it have to do with the fact that Linux mounts the filesystem? I assume that when I shut down Mint it unmounts the NTFS filesystem but maybe when it goes to sleep or if there is a power outage, maybe it damages the filesystem somehow. Any thoughts?
