"BOOTMGR is missing" and no operating system found

Hello

 

I have a Sony Vaio laptop updated from Windows Vistato Windows 7 Home Premium (32-bit). I upgraded 6 months ago and have had no problems until today. I tried to start my computer and got the following message: "BOOTMGR is missing" Press contol-ALT-delete to to restart.   

 

I've looked at answers on different forums. Most of them advised me to boo using the Windows 7 installation dvd. I've tried that but I then encounter the following problem:  In the Systems Recovery dialog box no operating system is found. This prevents me from moving on to the next step.

 

Any help would be greatly appreciated. I'm not very computer literate so, even for basic things, if any advise could be clear and simple that would also be grea.

 

Thank you

C

Hi,

References to Vista also apply to Windows 7.

This is serious error and "may" not be repairable without professional tech support from
a real computer shop (not leeks and peeks at a BestBuy or other BigBox Stores) or your
System maker's Support.

Here are the troubleshooting methods to try to fix the issue :

Try Startup Repair - (If at ANY point you gain some but not full access to Windows come
back and try Startup Repair again.)
