Hello Sir, Even after doing the 'Legacy' thing and saving it, when I turn on my Laptop, it again shows "Vaio Care" rescue mode.

Thanks

i have a sony vaio laptop cw series icore5 windows 10 (upgraded from w7 to w10 2 years ago). bought it march of 2010. yesterday i encountered "Operating system not found". this is the 3rd time i encountered this "phenomena" and each time all i did to correct the problem was UNPLUG THE POWER CORD FROM THE WALL OUTLET THEN REMOVE THE BATTERY. WAIT FOR A FEW MINUTES THEN PLACE BACK THE BATTERY THEN PLUG THE CORD TO THE WALL OUTLET THEN TURN ON THE LAPTOP LIKE I NORMALLY DID. THEN IT SAYS PRESS ANY KEY TO SKIP SCANNING .DURING MY FIRST EXPERIENCE, I TRIED TO NOT PRESS ANY KEY BUT THE SCANNING TOOK TOO LONG TO FINISH, ABOUT 5 HOURS, SO DURING MY 2ND EXPERIENCE I PREFER TO SKIP THE SCANNING AND ONCE INSIDE THE WINDOW I DID chkdsk /f. the scanning took only a few minutes where it says it fixed the problem. by the way, using "/F" only takes minutes and using "/R" takes hours..

Ahsan, Thank you, it worked for me :)

Thank you bro for solving this case Thanx bro🙏🙏🙏🙏🙏🙏🙏🙏

After push Buttom "Assist", sends me, again, to message "Operatins System Not Found".

Thank you it really works my laptop was again functioning

When I press assist button it's still showing operating system not found... please provide me solution if u can
