Updated Bios now unable to access any os on my system

Hello,
I updated my bios maxim extreme 4 did the bios upgrade after that was unable to boot into windows 7 which is on my d: Drive was able to boot into my c: drive which has windows XP installed played around with easybcd now it is all screwed up I now have my d: Drive showing up as 100 meg the remainder is now showing as F:Drive and I can no longer boot into my c: Drive XP Install now it just shows up no os found when loading.  I am able to boot up using a paragon backup disc so I am able to get into the xp Install only though the disk. I think I corrupted my Boot Records is there a way I can fix this. also I would like to get everything back to just C: and D:   I tried using easy bcd after i booted using the paragon disc backup but keeps telling me windows 7 is on the c: Drive

Thanks
J.T.

Insert your windows 7 DVD into dvd drive and when "install" option appear then don't click on it , just see at bottom "repair option" click on that after that open command prompt and then ttry the following commands.

1. bootrec /RebuildBcd
2. bootrec /FixMbr
3.bootrec /Fixboot

hope after this you will get windows 7 and then you can add the entry of windows xp too via bcdeditor

No way somebody can walk you through fixing this mess at this point. You need somebody who can use a binary editor to view the MBR and partitioning information and fix things.   Without having access to all the raw data then anything you do could just make things worse.

You need to just take your computer to a pro.  Sorry, it is way too late for somebody to tell you what to type in to fix it.

Sounds like you have two windows installed on there, which is installed first?
Which is the pre installed OS originally?
 Windows 7 or xp?
 it is not recommended to install xp on the same drive as pre installed windows 7, as windows 7 sees the BCD differently from xp and probably replaced the bootloader
Either install xp to separate drive or use the XP mode in windows 7
Things you can try to get xp back
Do you have access to safemode.
Take a look in there,
Or the advanced options select last known good configuration that worked and restore your system before flashing.
Or go into the bios and set it to defaults.ensure the date and time is correct as well. , save and exit.

Check the boot.ini in safemode for xp is correct and pointing to xp, you may have rebuild it since windows 7 will replace it.
In windows 7 the boot loader for Windows 7 doesn't use BOOT.INI
It uses something call a data store which resembles the registry.
in windows 7 you go to start> run > type in > msconfig and then open the boot tab.
 

You could also slave the hard drive so you can access your files to copy them out and even modify the boot.ini for xp  from another windows

You might get some good pointers here of the not to do.

I suspect your boot manager is on D (the old C) and the wrong partition is now marked active, that is the partition which the system is trying to boot from. To correct this requires that the original boot partition be marked active. Haven't had to do that for a while. I would have used fdisk or partition magic. Not sure what to use currently. Will see what I can find.

Ultimate boot cd has suitable tools. http://www.ultimatebootcd.com/download.html

Note that the 100mb partition you mentioned is normal, don't touch. This is a system reserved area.

p.s. weird time factor here. When I responded a short time ago, the two comments after the admin comment were not visible, but seem to have been made hours ago. Curious.

David Johnson, CD, MVPOwnerCommented:
As I mentioned previously the updating of a bios will reset the hard drive priority and boot drive priority.  If you had set it back to the way it was before the update then you would have had no problems at all.

Windows XP uses a boot.ini to locate the ntldr
This file normally is a hidden, system, readonly file
from a command prompt you can
attrib -h -s -r boot.ini and edit it in notepad

Typical boot.ini

[boot loader]
timeout=0
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
---

The "rdisk(n)" parameter is for the HDD drive number, where n=0,1,2,... depending upon which physical drive this HDD is in your system. The "partition(p)" parameter is its partition on that drive, where p=1,2,3,... in order, counting from a 1 (not a zero).

from a command prompt
type diskpart
from diskpart
list  volume
detail volume   << hopefully you gave your windows xp volume a meaningful label for example I see that it is volume 12
select volume 12  
detail volume
it will show you the disk # this is your rdisk value
select disk #  (the number that detail volume showed you)
detail disk <<this will show you the partitions on the disk, count them starting at 1  this will give you the partition # for the boot.ini

modify the boot.ini accordingly save it now try and boot into Windows XP

Ok here is were I got to over the weekend. I updated the Bios the Bios again after 1 another update came out now I can Boot into windows 7 problem was it hung on the bios screen for 4 minutes and then took 18 minutes to load Windows. So went into the event viewer seen cd rom kept coming up as an error removed it from the bios as a start up option so now it only takes 4 minutes when it hangs on the bios but boots normal after. So it Now takes me about 4 Minutes to load into Windows 7. I have not tried to boot into xp yet but I do get my options again. Now I just have to figure out the 4 Minute delay on Bios Boot Up.

Thanks

I object to the deletion of the question as I posted A Response I think might help People. It now allows me to boot into windows 7 with a 4 minute lag on the bios screen after that it boots no problem.

You just screwed it up further by attempting to boot a busted RAID that has stale information.   Had you taken my earlier advice and taken it to a professional, then they could have gotten much, if not all of your data back.

The author did NOT have a viable solution. All they did was override the broken RAID state and boot partially stale data.  This created further damage.

The solution is still # 37841037.  Professional recovery services.  That IS the only practical answer.   It is also the only useful answer.  This is NOT A DO-IT-YOURSELF recovery situation.
