Missing operating system error message

I recently got a virus on my computer that kept on eating my files. So I tried reformatting my computer to get rid of the virus. My friend gave me a installer for Windows XP which can be installed via USB. So I plugged in my flash drive and changed the BIOS setup to boot my USB first. But when I restarted my computer, this error showed up.

Missing operating system_

I don’t know what to do already. Please Help!

There could be a few reasons to your problem:

Incorrect boot priority settings:

Enter your BIOS again and check if USB-HDD has the highest boot priority

USB drive not detected:

Try using another USB port and reboot your computer to see if it solves your problem.

Invalid USB drive:

The USB drive that your friend pass to you could be invalid. You should test it out on another computer to see if the drive is still working as a bootable media.
 
Invalid USB Driver
 
Since your motherboard allows USB booting, it should by right have the correct drivers for USB detection. Still it is good to keep your BIOS up to date. Please refer to your motherboard's manufacturer manual to check how to update your BIOS
 
Hopefully these few steps will help solve your problem.

Possible causes of this error are:

1. Your computer could not detect your hard drive.

2. Your hard drive could be damaged.

3. The MBR or the Master Boot Record is damaged or corrupted.

4. The partition where the MBR is located is not active anymore.

To fix this, try to test if your hard drive is still working. Press and hold the power button to close the computer. And then while pressing and holding the F10 key, press the power button again to open the computer. When the BIOS Setup is already displayed, select Tools menu and then select Hard Drive Self Test. Press the Enter key to run the test.

You can also try to repair this by inserting the Windows XP installation disk. Do not reformat, just click Repair.
