Reader Question:
“Hi Wally, Our computer keeps rebooting and enters safe mode. I can’t get it to start normally. It shows the error” booting in safemode dsrepair ” before restarting.“ - Maria M., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: The Booting In Safemode DSrepair error can appear at random times but especially at the time when Windows is starting. It can appear in many different versions of Windows. This and other blue screen errors can be really confusing and  difficult to deal with. But once you have identified the problem, finding a solution becomes much easier.


The Booting In Safemode DSrepair or STOP 0x000000AA error usually appears when the computer is about to start. The error restarts the computer and enters safe mode. The user may be unable to use certain software and features as a result.


There are a few potential causes for the Booting In Safemode DSrepair error to appear, they are:

  1. The computer’s BIOS may be incompatible with the ACPI.
  2. Hardware or device drivers incompatible with the operating system may have caused this problem.


Here are some ways to solve the Booting In Safemode DSrepair error:

Change BIOS Setting From SATA to IDE

This solution only applies to computers that were released before Windows 8. So, if your computer came with Windows 7 or an older version of Windows then you should follow these steps.

You can solve the Booting In Safemode DSrepair error by changing the BIOS settings from SATA to IDE. SATA and IDE are two different interfaces used by devices like hard drives and optical drives (CD drive, DVD drive) connected to the motherboard.

  1. Click here to learn how to enter the computer’s BIOS settings.
  2. Once in the BIOS settings, look for an option to disable SATA. It should look a bit different on computers with different motherboards.
  3. Restart the computer.

Also try removing any new device drivers you might have recently installed on the computer. Remove any new hardware you may have started using with the computer such as a new graphics card. You can revert these changes by restoring a system restore point. Click here to learn how to restore a system restore point.

For Windows 8 And Newer Computers

If your computer came with Windows 8, chances are that it is using the UEFI firmware instead of BIOS. In this case, the Booting In Safemode DSrepair error can be solved by Uninstalling recently installed software and device drivers.

Undoing changes that caused the error can help remove it. You can also undo changes by using the system restore feature. If the computer keeps restarting before you can do any of this, then start the computer in safe mode and then try again. You can also try using the Windows Restore feature in Windows 8.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
