Windows 7 Startup Repair
The most common solution is to use a bootable CD, but it will be hard if it is not available to you; rather than booting from a CD and trying to repair the software, you have to use an alternative method that is not the same as the bootable CD method.
The great thing about Windows 7 is that it has a built in startup repair tool. This means that you do not have to install a separate repair tool that you will need every time you need to repair your operating system; instead, you can use the built in one that is easy to use. When your computer experiences a problem, it will automatically trigger this built in start up repair tool in order to analyze and fix the program for you. If it does fix the issue, it will reboot the computer, and everything will be back to normal.
Unfortunately, not all problems can be fixed via the start up repair tool. You will have to use a CD to try to fix this issue. You are definitely going to need a bootable CD or bootable file in a USB in order to use this method. Once you follow the instructions and get to the install screen, select all the basic functions and click proceed. This is not the most essential step, and you can adjust the time and etc afterward.
After you input those information, you will be taken to a page where there is an option to repair your computer. Click on that option, and select the operating system (Windows 7) from the options.
Once you continue following the directions and steps, you will arrive at a stage where you have 5 different recovery options. The first thing you should try is the start up repair as it will scan your computer file to see if there are any problems with the booting process; it will fix any issue that occurs during the booting process itself.
If that does not work out for you, you have the option to restore your system to a setting that has been automatically saved. This means that it will revert back to the original setting that was working before, so you are guaranteed to fix the problem since it was working before the problem occurred.
If you have saved a file of a working Windows 7 beforehand, you can use the system image recovery in order to load the certain setting that you have saved in the past. If you have never heard of this function before, it may be a good idea to save an image of the computer after you finish fixing this problem!
Lastly, there is a windows memory diagnostic tool that will scan your random access memory for any errors; if there are problems with the RAM, your computer will have a hard time booting. If the problem is not within the software itself, it is most likely a RAM problem that is preventing you from booting up!
After trying all these steps, your computer will most likely have been fixed!
