Windows 7: Disk boot failure, Insert system disk and press enter

I've been having this error even after reformatting and reinstalling Windows 7 on my desktop. I've done reformatting / reinstalling Windows 7 several times, yet the problem still occurs. I'm thinking of my HDD as being corrupted or messed up. The problem occurred after I accidentally hit the CPU when I was stretching my foot. The screen froze after that. Upon rebooting it, 'Disk boot failure, Insert system disk and press enter' occurs. After I entered the DVD installer of Windows 7, the screen just hangs. How can this be fixed?

hello..how many times you're already reinstall the OS??

Hello dothackjhe, welcome to Seven Forums!



Find the manufacturer of the Hard Disk Drive (HDD) at the link below and run a diagnostic on the HDD to see if there are issues.

When you said you kicked the "CPU" did you actually mean the processor or something else?

There is indeed a problem with the HDD. T_T After undergoing diagnostic test with the hardware, the HDD was shown as the root cause of the problem. I can't seem to start the PC without having the need to insert the install disc for Windows 7. T_T Is there any way I could fix this HDD, like reformatting it to a factory setting? There really seems to be a bad sector in the HDD. T_T

No, I just accidentally hit the CPU case at its back. Not too hard that will cause it so much harm though.

I was able to reinstall Windows 7 without freezing the screen. But after shutting it down and turning it on, the same error occurred again. I got it running (but not fixed) by using the command prompt in the Windows 7 install disc and have it check for any errors at startup --- HDD was the root cause. T_T

Have you moved the connecting cables for the HDD around recently?



Were there no repair tools you could use for your HDD at the link I posted?

I did moved the connection for the HDD to the other slots wondering the slot where it was inserted is failing on it.

The main root of the problem started when the PC won't boot. I placed the RAM to the other slot thinking the slot where it was placed is busted. The PC booted after moving the RAM stick to other slot. Then I decided to dual boot Windows 7 Ultimate with our old copy of Windows XP SP3. I was able to install both OS in different partitions. I used a 3rd party software to fix the boot manager for XP. XP is working just fine after, but 7, on the other hand, randomly freezes (probably due to problems with the registry). 7's boot can't be fixed after its last freeze so I decided to reformat the HDD to give way for a full install on Windows 7 Ultimate alone. Then I learned that Windows 7 has a 'Windows XP Mode' that would be run in a virtual box under Windows 7 itself. Everything was just fine when the PC hanged again. After several reformat-reinstall of OS attempts and a sudden little impact on the back of the PC, I've been having a 'disk boot failure error'.

I'll go check if there's any repair tool that will work on this HDD from the link you've provided.

I'm currently downloading the Disc Wizard Setup for my Seagate SATA HDD. .

I hope it helps you out.
