Answer 1

Perhaps you aren't getting answers because you are interjecting your issue into other old, closed threads like this one that have nothing to do with your issue at all.

Do a clean install of Windows XP. You'll need to use your Vista DVD to do a startup repair afterwards to get back your dual boot.

I have NOT been ABLE to BOOT my XP partition properly via every other means...

1st of all, I have posted in several threads which returned w/ no significant solutions to my problem, which was initialised when I accidentally formatted the HDD with XP partition with a Linux (OEM ASUS EeePc) onto my ACER Aspire 4720. It was configured to run on 2 OS ( Dual Boot- Vista & XP) WHICH WORK Perfectly fine prior to that.

what I did then was, I immediately do a HARD shutdown within 5 sec (using POWER button) then removed installation CD from DVD-RW drive... but it was TOO LATE...  SERIOUS DAMAGE  have already been done to the booting record (MBR).

So, I search on various recovery remedies on many different Forums including this one. Come to conclusion, I decided to start from the most basic recovery, thru WINDOWS  installation CD/DVDs. But it was beyond recognition by BOTH Windows (perhaps because I formatted BOTH WINDOWS under NTFS and LINUX uses a FAT12 instead ) which brought me to next STEP..

I downloaded Hiren's CD 10.4, run em and added several other recovery softwares into USB stick...

Long story short, I managed to retrieve VISTA completely, leaving the XP unresolved, so I retraced back to STEP 1 THEN 2

NOW, using various well known recovery softwares such as EasyBCD , Partition & Mount, etc to restore XP haven't changed my luck a bit..

Initially, it showed that NTLDR is not present, So I did paste all the files into C; & D: ( C: Vista ; D: XP, which was reversed automatically by Vista after installation, being the 2nd partition)

I even try to do Repair Installation via CD but it returned to null...

because  ACCESS IS DENIED!

So I resetted Admin pwd and so on...

Then, after being able to log on, tried again then it showed : Stop Error 0xc0000218, registry hive can not load...  system32..../SAM after REBOOTING..

Hence I followed the online instructions to MANUALLY CHANGE  registry by using recovery console of XP CD.. but only managed 2 get to STAGE 1...

because after REBOOTING ... it just went BLANK!

EVEN  when I tried to do a Repair Installation, I just was not presented w/ 1 anymore..

I then go to edit those lines under Vista and restart to find this problem:

Windows could not start because: \Windows\system32\config\system is missing or corrupt...

then I rename it under XP Recovery mode..

Now it always reboot in loop whenever I tried to log in to XP, no access whatsoever to Safe mode ,etc (even when I depress F8 while it booted)

Vista is working fine...

What should I do next?

Please HELP!!!

I have a Very Important software that is IRREPLACEABLE in terms of value and it has SERIOUS imcompatiblity issue w/ upgraded / advanced versions of Windows ( Vista or 7) other than XP.

Can anybody provide me w/ a MORE IN-DEPTH DETAILED SOLUTIONS (like a walkthrough / cheats to uncover certain upgrades in Games.. ??  ;) ) to recover my XP??

Thanks a million beforehand,

Chan

Answer 3

Again, you would need to give me the exact text of the error message and some information about the recent history of the machine.

Answer 5

Without knowing the exact text of the error message, I can't give you specific help. However, since you can't get into Safe Mode and don't have a Windows XP CD your options are limited. Can you get into Windows using Last Known Good Configuration? You will find this option on the same diagnostic menu as Safe Mode. If you can't get into Windows using LKGC, then you would need to:

1. Pull the data from the hard drive if necessary, which can be done even if you can't get into Windows. Let me know if you need instructions for this.
2. Test the hardware to make sure it is good.

3. Try a repair install of Windows.

4. If the repair install doesn't help, do a clean install/factory restore of Windows.

If you can't do the work yourself (and there is no shame in admitting this isn't your cup of tea), take the machine to a professional computer repair shop (not your local equivalent of BigComputerStore/GeekSquad).
