For a couple months every time I started my computer it went into recovery mode and then turned on. Today it says "missing operating system" and nothing else.

Please post the full spec of your PC (Make and model of Motherboard, CPU , HDD , RAM etc ) in case it is an assembled one and Model number and service tag in case it is a Laptop or Branded PC.


"Missing Operating System" is generally happens due to corrupted boot code . Boot code corruption may be happened due to a failing HDD. Please try the following steps.


1 ) Replace the SATA cable (in case of PC. If you don't have a spare one swap with DVD drive cable) or remove and re insert the HDD if it is a Laptop.


2 )Boot from the Windows 7 DVD and follow this step by step tut to do an automatic startup repair attempt :





If the above steps can't solve your issue, then we need to test your HDD health before performing any manual repair attempt. Waiting for your reply.

Hello, may be a simple problem: A USB FLASH DRIVE plugged into your PC. Remove and reboot the machine! Sorry the wrong words, translated by Google Brazil.
