    Windows10 only starts from CD at boot-up..


    since a recent update - can't remember which one - Windows10 will only boot from CD
    I have had to change the boot-up sequence in BIOS to enable this, as the system wouldn't
    boot from the main hard-drive..

    - is this a common problem and is there a solution..??

    - obviously this is a serious glitch..
    - I am having difficulty getting sfc/scannow to run, in order to effect a repair

    - Unless a solution is possible, a roll-back to Windows7 may be the only solution
    - Windows10 TP10041 appears to be seriously unstable at present..

    Windows 10 isn't "seriously unstable". Your installation has issues. Don't confuse your experience with your one installation with all of Windows 10 for everyone.

    sfc hasn't worked reliably since the first Windows 10 release, this is a known issue.. you just can't rely o it. Some people have reported getting It to work for the first time in 10041, but others have not.

    This is a technical preview. It's unfinished software. So yes, it has bugs. Yes, it might even completely wipe out your system. However, for most people it's generally stable.

    Your issue is probably unrelated to any update. You probably had a virus or something wipe out your boot sector, so you need to rewrite your mbr...
