Last Modified: 2011-09-20
our server is having os win 2000 advanced server and have RAID controller also. it's not booting now saying INACCESSIBLE_BOOT_DEVICE...

i tried using startup disks (4 disks) with RAID setup disk to get into recovery console and run CHKDSK /R/F and FIXBOOT. it went smoothly without fixing the problem. i cannot risk running FIXMBR since we have valuabe data in hard disk.

please help

I don't think you have anything to fear from FIXMBR - but why do you feel you need to run it?
It may help - but it may not...
What's the exact error you're getting?  We need those four hexadecimal codes that are displayed...

A repair install should do it for you tho
Do you have the driver for the array controller?
You'll need to put that on a floppy disk and press f6 during setup

Is your RAID-Controller in the bootlist of your BIOS? Is it configured to boot from?


sirbounty, may be my question was not clear. let me breifly explain it

our server was working fine until yesterday. uninstallation of SQLServer2000 and installation of MSDE went fine last day.

when i restarted the machine in the end of the day, the error came.

*** STOP: 0x0000007B (0xEB41B848, 0xC0000034, 0x00000000, 0x00000000) INACCESSIBLE_BOOT_DEVICE.

i restarted the machine with win2000 boot disk by pressing F6 first and RAID driver disk. Repaired the disk, run CHKDSK /R/F and FIXBOOT, but without any good news.

is there any method to fix this problem without really re-installing windows 2000 server ?

i don't want to re-install windows 2000 server since i am not good with windows 2000 server and afraid of loosing any setting we have made there.

This PAQ may help: http:Q_20637525.html

MS's general troubleshooting (though not very helpful)...
http://support.microsoft.com/?kbid=324103 or http://www.jsiinc.com/SUBL/tip5500/rh5534.htm (better format imo)

But, I think you may be limited to a repair installation at this point...

You won't lose installed software, or data - you will just need to reapply any updates that have been applied...

It sounds like the un-install program for something removed a shareed system file, or maybe you RAID card drivers have somehow become corrupted.

If you install windows to the same place (e.g. C:\WINNT) it will just install windows over itself. All program settings will remain and you won't lose ANY data on your disk, so don't worry.

If the server still doesn't start you'll have to bite the bullet and restore the system to how it was last time you made a backup tape. you will have to bear in mind the loss of any data since your last backup (should only be a few days difference though, depending on how often you backup).

If the data stored on there is really important then put another disk in the server and copy everything off as soon as possible.

Before you re-intall 2K Server you might like try booting into safe mode (F8 on startup) to see if you can spot anything wrong there.

It is also possible that a new service that has been installed is preventing the system from booting.

Look here:

If this is the case then it is possible that re-installation of windows over itself might not fix the probem (but trying certainly couldn't hurt).

Ensure that the floppy drive cable is inserted correctly if the floppy drive is the first device to be booted from in the BIOS.


guys, i called a service man and he solved the problem. actually we were using SCSI hd and RAID controller for IDE hd. so it was bios confilctioin according to the service man.

anyway, thanks

How strange! :o) I wouldn't have thought that a BIOS conflict would suddenly 'happen', especially since the problem seemed to coincide with application installation/un-installation.

Well, I'm glad you got it sorted out in the end.
