Not sure if this is a hard drive issues. I bought a new 250 gig Seagate HD to put into my Asus A8N SLI deluxe. After I hooked it up. I was asked to partition it. So I did as to what it said to. I installed Windows XP Pro. And when it started the reboot I get the message. " Error loading operating system". I have been looking on how to fix this with no luck. Please help.
Since you got to partition it, i'm assuming you hit F6 to install sata drivers as i could never see the drive if i didn't hit F6. Re-partition the hard drive, format the partition using NTFS(Quick) that you plan to install windows onto and watch it reboot, hopefully it works next time for you.
I have exactly the same problem. I have bios 1015. My solution 1½ years ago was to boot from an old drive, and use the seagate sata II drive as secondary. Now the old drive is broken and I tried once more to install on the seagate without any luck.
i see alot of posts about this issue but none like the one im having trouble with i have a computer that is somewhat old and was built for me i have no recovery cd's or anything for the computer for that matter and i was in the middle of everyday things when my computer just shut off when i powered it back on got the message error loading operating sys i dont know what the hell to do only thing i can access is start up and boot menu's i tried taking harddrive out and putting new one in and thats not working its asks me about boot device and wants me to put start up device in and reboot is there any hope for this computer?
I am having a similar problem. I cloned my 36 gig drive to a 74 gig drive and am getting the error loading operating system message. I have the A8N-SLI with bios 1014. I hooked the drive up to a different computer and it boots up fine. I think I tried changing the access mode to Large and that didn't work. Any help on this is much appreciated!
This rumour that it is BIOS / HDD issue is not true
What is true is that it is a issue of HDD geometry
The issue is what is written to the HDD not BIOS
This is proven by the fact that I got 6 new HDD's Same make model and batch. I created the fault on one drive. I then installed XP onto a second and third HDD both of which worked absolutely perfect.
I then cloned the DUD install onto the working HDD guess what the error was reproduced proving that the issue is actually what is written to the HDD.
To prove that it is NOT a HDD fault and is only what is written to the HDD I cloned the 3rd HDD that was working perfectly back to 1st & 2nd HDD
All three drives then booted and worked perfectly
This establishes the "error loading operating system" is a function only of what is written to the HDD, it is not a HDD or BIOS issue at all.
Anything said to the contrary is a myth or just misinformation by the uninformed or uneducated or random luck.
As to what is written to the drive and what to change in general the following has been proven on the drive that was produced with the error
1 The partitions were all accessible no error
2 The files were all accessible no errors
3 FixBoot & FixMbr just does not fix the problem
4 BootCfg /Rebuild just does not fix the problem
5 SystemRoot c:\windows did not fix this problem
Now in summary
We do know its NOT a BIOS or HDD fault
We do know its a software problem written to HDD
We do know that it can be fixed by overwriting
We know FDISK on XPBOOT from BootDisk.com does not work its Win98 & makes it worse (wrong version)
What I can tell you is cloning the drive with O&O repairs the problem on the target HDD if you say yes to the question "the original appears bootable do you want the target to be bootable Yes / No"
What I don't have yet is quick fix that works, I will test any serious suggestions for solution
