My computer was a dual-boot system (Windows XP and Mandriva Linux 2007, both x86-32bit). LILO was the boot loader.
I urgently needed free space on NTFS, so I decided to kill my Mandriva Linux's installation In Windows I used Norton Partition Magic to format Linux ext3 partitions to NTFS. It worked fine I got fresh 30 GB on NTFS.
Good! Everything is OK - it was what I thought in such day...
Next day, when I powered on my computer Windows did not boot! The screen always becomes filled with 0 and 9...
Damn, LILO is alive in MBR, but since it cannot read lilo.conf file (which was on ext3-to-NTFS formatted partition), computer is absolutely unbootable!
I made a Google search (corrupt mbr windows xp linux fix) and I found an hypothetical solution Boot computer with Windows XP CD => go to Recovery Console => run fixmbr command.
I tried this but I found a terrible problem Recovery Console asks for Administrator PassWord I thought it should be my LogOn PassWord, since I am the only user and I am administrator (I have administrator privileges).
I was wrong Recovery Console always says Wrong PassWord! Then I discovered (via Google search) that my account is the only one Real Account, but also exists 3 Ghost/False/Pseudo-Accounts (which I had never known before this) - Adminstrator Account, ASP.NET Account and Guest Account.
I have no idea what this means; what does this accounts exists for?; why does exist this useless accounts; who created them????
Thus, I have no idea what is the PassWord Recovery Console wants...
I also saw many guys talking (in forums) about using a Windows 98 or FreeDOS boot disk, to boot from them, and then run fdisk /mbr command... It seems this solves nothing because Windows XP (this is NT Family - NT, 2000, XP, 2003, Vista, 2008) have an absolutely different boot process form DOS, Windows 95, 98 or ME (MBR; ntdetect.com; ntldr; boot.ini).
My third failed trial/attempt/test => GpartEd Live CD <=> this is a superb tool to manage partitions (create new, delete, format, re-size), however, it cannot restore a corrupted Windows XP MBR...
Alone, I cannot go further... My knowledge's limits are reached... I need help!
So, I am here asking for help specifically how to restore Windows XP MBR, overwriting LILO?
Thanks in advance!
