    Windows 10 missing after installed Windows 7


    Today the day became worst when i format my windows 8 to installed windows 7, then i found i am not getting the dual boot option for Windows 10. I tried startup repair through windows 10 dvd but it is only showing win 7 for repair, no windows 10?? *Eek

    Both OS partitions were different C and D. I can see Windows 10 files are still in D drive.

    How can i get back my Windows 10 again... i lost it somehow.....*cry

    :)

  2. My computer has "crashed" twice on my toshiba laptop and once on my HP laptop after windows 10 upgrade

    I have upgraded to windows 10 the first time from windows 7 and the computer just died we could not do anything on it, we ended up after buying windows 7 and 10 disc and still not being about to clean install, we had to purchase a new hard drive and go
    from there. Well after replacing hard drive we installed windows 7 and upgraded to windows 10 (not thinking it would be the cause for it to happen again) well it did happen again, this time the computer does not seem to be missing a hard drive but it will
    not clean install an OS and is telling us it is missing drivers. Can anyone suggest what is wrong or what we need to do.

    syncing files with external drive.

    after installing windows 10... the sync file with external HDD feature has disappeared. Am I missing somethiong or has there been a downgrade from windows 7?

    Run the following commands at the command prompt.

    diskpart
    list volume NOTE: Note the volume letter where the Windows OS is installed.
    exit

    bcdboot X:\windows NOTE: Replace "X" with the volume letter of the Windows OS partition.
