Hi

I have an assembled Desktop PC and it was working fine until now. But recently when I tried to boot it is not booting and error message appears as below:

1. Insert your windows installation dis and restart your computer.
2. Choose your language settings and then click "Next"
3. Click "Repair your computer."
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

File: \Windows\System32\winload.exe

Status: Oxc000000e

Info: The selected entry could not be loaded because the application is missing or corrupt.

So when I tried to change the Boot Priority Order to Optical Drive/Removable Devie in Bios it appears in while but when I make selection it is not being selected. I tried various ways to overcome the problem in BIOS but to of no avail.

Please help me to find a solution to this BIOS option so that I can get the Operating System to either get installed or repaired by inserting Installation Disc/USB.

Thanks for your patience to get to know my problem.
