Below are my dual boot settings. Both are on different partitions, default is Windows 8. Both were working fine. There are multiple users of this machine, few run 8 while few 7. All 7's users are novice and they use Internet only. I frequently update Windows 8 but not 7. Few weeks ago, Win 7 stopped booting. Machine gets restarted while booting with 7(Windows 7 start up glowing-Win-logo-screen does not appear) and the 8's loader reappears. Win 7's partition still exists and contains Windows folder What steps should i take to check the problem?
