Excuse me, just read the forum rules and then post. If you have a specific problem please post it with enough details that people can actually identify the origin of the problem and tell you the remedy. Just do not post that you have a problem.

"Error Loading Operating System" Error Message When You Restart Your Computer During Setup

By trial and error I found in my case that by selecting LBA mode instead of CHS mode in the CMOS setup fixed the problem. Hopefuly that might help you folks with the similar problems.

There are way too many causes and solutions for me to post. So a google search will help-

@the tech freak--the problem persists even in lba mode..
every now and then i have to format c drive which is ridiculuous if one has to do it every week.

Some extra info--
i asked to a computer guy he told its problem wid hard disk bt another said its wid ram .. iam totally confused.

do a memtest with your RAM, check here.. Memtest86 - Download Page

if its not a problem with RAM then hard disk is the culprit ... may be bad sectors..!

BTW how old is u r system..?

@khmadhu- my system is 3 years old. In bt i had upgraded my ram to 1.5 gb. Initially it had 512 mb ram.

Its most probably Hardware fault. And I guess Hard Disk. Could be bad sector problem. My friend had kind of similar problem. I think RAM is good but still do the memtest. Try to install the OS on other Drive I mean like d:\. This may help not sure though.

Try using Win7 or Ubuntu & see if the prob persists

Tell me that, for 4-5 days you can boot into the system normally, but after, a few days the problem crops up?
