Sometimes when you boot your System you might get this error 0x490 and you won’t proceed from there. This happens if the Boot Manager is damaged or corrupted. In such a case, what we have to do, is we could run a Startup Repair.
- Run Startup Repair in Windows 10 using the Installation Media or via Advanced Startup Options.
- Run Automatic Repair in Windows 8
Startup Repair in Windows OS
While the example shows Windows 7 installation media, the process is the same for Windows 10 too.
To do so:
- Insert the Windows installation disc or USB flash drive, or a system repair disc, and then shut down your computer.
- Then restart your Computer
- When prompted, press any key, and then follow the instructions that appear
- On the Install Windows page, or on the System Recovery Options page, choose your language and other preferences, and then click Next.
- Click Repair your computer.
- Select the Windows installation you want to repair, and then click Next.
- On the System Recovery Options menu
- Click on Start Repair
- Startup Repair would run the Repair process
- After the process is over and fixes are applied, the computer would be re-started.
On some occasions, we might need to run the Repair, 3, or 4 times to create the boot files to a new location.
Each time we have to restart the PC.
Some common FAQs about Windows Startup Repair
How do I use Startup Repair?
If a startup problem is detected, Startup Repair will start automatically and try to fix the problem.
If the problem is severe enough that Startup Repair doesn’t start on its own and you can’t access the System Recovery Options menu on your computer’s hard disk, you can get to the menu and start Startup Repair by using the Windows installation disc or a system repair disc that you created earlier.
Are there problems that Startup Repair cannot fix?
Startup Repair can only fix certain problems, such as missing or damaged system files. It can’t fix hardware failures, such as a failing hard disk or incompatible memory, nor does it protect against virus attacks.
Startup Repair isn’t designed to fix Windows installation problems, nor is it a backup tool, so it can’t help you recover personal files, such as photos or documents. To help protect your computer, back up your system and files regularly. For more information, search for “backup” in Windows Help and Support.
What if Startup Repair can’t fix my problem?
If repairs aren’t successful, you’ll see a summary of the problem and links to contact information for support. Your computer manufacturer might include additional assistance information.
