Sometimes when you boot your Windows 11/10/8/7 computer, you may see Error Code 0x490 and you won’t be able to 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 Automatic Windows Startup Repair.
Fix Error Code 0x490 on Windows Boot
To fix Error Code 0x490 on boot in Windows 11/10/8/7, you can follow these suggestions. Since you cannot boot Windows normally, you may have to try and boot in Safe Mode or into Advanced Startup options screen to be able to carry out the fixes. You will need to make use of the Command Prompt.

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.
