Ever wondered why your Windows 7 PC not able to load properly and inbuilt utilities like Startup Repair won’t able to fix this issue? Moreover, startup repair keeps coming again and again but didn’t able to repair problems of your computer. If you’re unlucky, other troubleshooting options like ‘System Restore’, ‘safe mode’ and similar to fix unbootable Windows system will not work either.
Previously, Startup repair is used to heal problems with your computer by repairing or replacing important system files, fixing registries and removing problems with third party installed software. However, in some cases startup repair seems useless as it might not able to detect the exact cause behind the problem or the startup repair itself facing difficulties with system registries or the conflicting windows system files.
In such cases, you've got only one option to make your Windows system working again. That is, by reinstalling a fresh copy of Windows which involves risk of losing everything stored on your computer along with all the installed applications being removed completely.
What causes ‘Startup Repair’ to Loop?
There might be bunch of reasons that causes startup repair to loop infinitely. However, we’ll group here only few popular reasons of why this is happening with your computer along with subsequent steps to fix it.

Some other possible reasons could be malicious programs installed on your computer that you haven’t noticed yet. It may have high vulnerabilities of damaging system files and other registry settings which prevents Windows to load properly and prevents other system options to troubleshoot Windows.
In both the cases, you can easily get rid of all the problems and roll back your old Windows in working state by performing clean installation of Windows. Again, doing this will compromise you to lose everything stored digitally with no traces of deleted files and folders, which makes data recovery impossible on your computer even by using most powerful data recovery applications.
