is to backup all of those "Important files" you mention. It's your choice but with all the installing/re-installing you are doing, you are going to lose those files at some stage, then you have lost everything.
That has to be the most important job before you do anything else.
When you have done that, then since this problem keeps recurring upon install/re-install, I would then use that genuine XP CD to reformat the whole drive and install XP as a fresh install.
I come across very strange problem. Last week my machine running XP Home was infected by 'Boot.Mebroot' virus which curropted my boot configurations and my machine was getting restarted upon loading windows. I tried all the options but no use.
Then I re-install (Upgraded to) XP Professional with complete installation without reformat and updated to latest SP3. It went fine, I ran Symantec and found the ****** and kicked off from my machine. Then I started Windows Live update as I want to bring my PC to latest patches. All the updates got installed without an error (about 58 updates most of them were security update, SP3 and IE8). As soon as I restart my machine it shows the same behaivour. It get restarted. I Repaired my XP professional three time now.
Why I am accusing MS XP Update for all this because Last night everything was running absolutly perfect, I started the update it showed me 58 updates. All update gone successfully. After finishing the the updates I simply restarted my machine and it failed again and restarting again and again. It shows me F8 boot options and I tried all but same. So I repaired this morning again.
I tried the 'fixmbr' command in recovery console and it displays the dangerous message that 'This machine boot have some problem' but if you ruin FIXMBR you might loose the partition and stuff so I didn't run it as I have very important data on my disk.
Is there anyone who can help me with this problem please.
Thanks & Regards,
