: hard disk dected by bios but not booting can any one help me


Not much to go on. Could be virus, could be damaged master boot record, could be bad HDD, maybe something deleted your files, may NOT be the HDD, could be ... Did you do anything to your PC recently, like just before you developed the problem? Any unauthorized "users" (like bright kids)?

Suggest that you do non-destructive things first - that is INSPECT with some programs, write down and post the results BUT DO NOT CHANGE ANYTHING until you know what is wrong and how to deal with it. Even if partitions were deliberately deleted it is possible to recover ALL of your files IF IF IF you don't change anything (NOT easy, but possible).

Download your HDD maker's diagnostic utility and the instructions for using it - you will need/want it eventually so go ahead and get it now.

I'm assuming that you are running win9x and you have some files you want to keep. Please post what OS you are using and maker, model and capacity of your HDD; likewise for the rest of your PC if you changed anything shortly before the trouble began.

One of the easiest things is to try to display a directory/folder, another is to inspect the partitions with fdisk - if no partitions or missing partition(s) - you're into data recovery (DO NOT CHANGE ANYTHING).

Boot to a windows setup diskette - win98 setup diskette is a good one for this. If the FDD won't boot check CMOS Setup - make sure the FDD is the FIRST boot device. If the FDD won't boot - your HDD may be OK, but you're into hardware troubleshooting onstead of just HDD.

First, at the DOS prompt try to display the files in a directory (dir c:). If you can see files the HDD is working but you may have a virus that has damaged the MBR; repair it at the DOS prompt (fdisk /mbr) and try to boot up. Please Post Results.

If sector zero has gone bad (fdisk /mbr can't fix it) - your files are possibly OK but you cannot boot the drive (without some high powered work)

If you cannot see files with dir c: then try to display the partitions. At the DOS prompt (fdisk). Choose option 4, display partition information. Please Post Results.

Check your HDD Diagnostic utility - it SHOULD have some non-destructive tests that you can run without risking loss of your files. DO NOT run a write/read/verify utility or function - it is a DESTRUCTIVE function that will erase your entire HDD (you MAY need to do this eventually, but NOT until you get your files - IF that is possible). Please Post Results.

There's LOTS more - depending on the results you get.

Hope this is enough to get you started.

Henry
