    Boot Problems

    All 3 64 bit operating systems of my PC (Win 7, Win 8.1 and Win 10 Tech Preview) were booting without problem, but now I can only boot Win 8.1. The failure to boot Win 7 or Win 10 TP is apparently to do with the System 32\winload.exe file being missing or corrupt. (The files are not missing, so they must be corrupt).

    I would greatly appreciate information as to how to correct this.

    Thanks and regards, Roy

    A week ago I downloaded and installed Win10 TP on my 480GB SSD which also has two Win7 OS partitions (32bit & 64bit). All seemed well until I rebooted into one of the Win7 partitions; chkdsk ran on all three OS partitions and on the two partitions on my 2TB HDD.

    After some Google searching, etc., I found that the chkdsk problem was caused by Win10's "fast startup" feature (Win8/8.1 also have "fast startup"); I turned off "fast startup" in Win10 and chkdsk has not run again since.

    See: Win7/Win10 TP NTFS woes.

    I used Easy BCD to solve the problem.

    ?Would booting up Windows 7 DVD and running repair help? I've done this a few times for my Windows 7, however, I am not dual-booting. I hope to learn if running repair would hurt the nonWindows 7 partition.

    Running the repair function from a Win7 DVD shouldn't affect any other partition(s).
