Startup Repair - or Automatic Repair in Windows 8, 8.1, and Reset in Windows 10 will try to automatically repair computers that are unbootable because of any of a number of reasons.

Startup Issues this guide can help with :

Has your Registry become corrupted?

Are there missing or damaged system and driver files?

Are you experiencing Disk metadata corruption like MBR, partition table, and boot sector or file system metadata corruption?

Having issues installing problem or incompatible drivers?
Installation of Windows service packs and patches coming back with incompatible errors?

Corrupt boot configuration data?

Bad memory and hard disk hardware errors?

You will want to run a Startup Repair when you are experiencing these issues, but while its early enough that no other issues have been caused as a knock on effect.

This tutorial will apply for computers, laptops, desktops, and tablets running the Windows 10, Windows 8/8.1, Windows 7 operating systems. Works for all major computer manufactures (Dell, HP, Acer, Asus, Toshiba, Lenovo, Samsung).

Hey MDTech. This problem happened 2 days ago when I was logged into a non admin account on Windows 7. I recently installed an app which was working for the most part but had a slight issue. I also noticed that a driver updated failed to install but only click to check on it and closed the window. mins later my screen went zoomed in and desktop background turned black and missing icons. I did a System Restore to last month and desktop background is normal along w/ some desktop icons showing. Only problem is all my files are missing from my folders and can’t find them anywhere even when I check my C drive and Old.Windows folder under user. Idk what happened maybe a corrupt file also had to Re-install chrome & bookmarks gone, also getting error code 0x0000142 every time I log in. Any help would be appreciated! Also I tried this method but instead of C: Drive it’s on D: Drive.

My comp. starts ok and works ok. But since a couple of days, it acts weird and slows down a lot. And web browsers freeze a lot and programs start very slow. I have installed my windows 7 about 3 or 4 years ago. I think the system is full of windows errors and corrupt windows files after all those years. Is there an easy way of repairing everything?

[marioskrouemadis]

Hey man what to do when the reset to a previous state fails? I have tried reseting it to many diferent points but still nothing. It says maybe a firewall blocks it but the thing is i cant open close or delete my antivarus cause the reason i wanna do the reset is because some programs stoped working, one of them being the antivarus, can u please help me?

For start-up repair you needs bootable CD or USB then you can as per your installed windows.

Why it says that " STARTUP REPAIR CANNOT REPAIR THIS COMPUTER AUTOMATICLLY

[j.lietka]

If you click on the "X" (close) or "Cancel" it won't allow you to do either. But if you press the power on/off button, it should bring you to the Recovery Manager screen. Did it on my Compaq CQ56!

System restore only goes back so far.What if it happened before your log dates and you just found out about it ? Windows only keeps those type logs so long.
