Thread: Error loading operating system

I built a new PC using an ASUS M2N68-AM-SE2 motherboard running an AMD Sempron processor, 1 GB Kingston memory and a 160 GB Western Digital hard drive. When I install both 32-bit and 64-bit Windows operating system, it gives me an error saying "Error loading operating system", The system boots with the installation disk, it copies the files to HDD but when it reboots, it says "error loading operating system". I tried finding solutions online, people suggest enabling LBA mode but it is already enabled.

It could be some problem with the BIOS or the drive. Enter the BIOS before boot up and check whether the drive shows up in the list. Try using some other hard drives and see if they work or not. Try replacing the cable as well and also scan the hard drive for problems using a drive diagnostics tool. It could also be some issues with the partitions on the drive. Format the partition you are trying to install the OS on.
