  • Does repairing a MBR affects the current data and apps installed on the PC?

  • Kapil Arya

    ^^ Nope 😊

  • So when I did this it did the following:

    1 – bootrec / scanos
    “Successfully scanned windows installations. Total identified windows installations: 1
    2 – bootrec /fixmbr
    this operations completed successful
    3 – bootrec /rebuildbcd
    “successfully scanned windows installations. total identified windows installation: 1
    [1] e:\windows.old\WINDOWS

    It then asked: Add installation to boot list? Yes(y)/No(n)/All(A)

    what do I put and what do I do after this?

    Will this process erase all my files, documents or photos? Thank you in advance

  • Kapil Arya

    ^^ Type “Y” and add identified installation to boot list.

  • Well it doesn’t look like my message went through so I will redo:

    so I did click Y to the add installation to boot list. then restarted my computer. it still starts up with preparing automatic repair, then goes to diagnosing your PC. the automatic repair page came up with shut down or advanced options. when I clicked on advanced options I have the following options

    1. Continue: exit and continue to windows 10

    2. Use another operating system: continue with another installed version of windows (this is new) it gives me the options of Windows 10 or windows 10 home. I tried windows 10 home and it comes up with “recovery” and states “your PC/device needs to be repaired. the operating system couldn’t be loaded because a critical system driver is missing or contains errors”
    File:\Windows.old\WINDOWS\system32\DRIVERS\tmelsys (not sure if there is a dot inbetween the l & s)
    Error code: 0xc000000f
    you will need to use recovery tools

    It also gives these options
    1. press Enter to try again (did that and nothing)
    2. Press F8 for startup settings. this had options such as enable debugging, enable boot logging, enable safe mode which I tried and nothing)
    3. Press F9 to use a different operating system (tried that and chose windows 10)

    I have also tried go back to the previous version and it does nothing

    any more insight you could give would be appreciated and thank you for your time.

  • Still having issues.

  • I have tried the same things that you have tried, and nothing has worked for me either. Are you still having problems or have you found a fix? Thanks!

  • I’ve spent hours attempting to do this by reading directions on various sites. In most cases, the directions are incomplete or incorrect. I’ll get up to a certain point, and then there’s no where to go.

    I eventually got the ISO of Windows 10 installed, but I was unable to Activate it. Since that ISO had been installed originally when Win10 was free, it was never registered, so I was not able to register it after I installed it.

    I thought I would continue to use the computer without Activation. However, the next day, the computer restarted on its own, and I got the same blue screen message. “…a component is missing…”

    Microsoft makes it too difficult to install an OS. There’s another computer company that makes it extremely easy. Start the machine with Command-R, and that’s all it takes.

  • How do I do after I had my laptop updated to a latest version of Windows and it won’t start and keep showing Asus logo
