my situation is as follows :

previously, i installed a copy of winxp sp3 on my new hard drive, with the old copy on my old drive not formatted yet. after which, i used my hard disc DOS tool to format the old drive, and subsequently it changed my boot partition letter, hence screwing up my bootup ( NTLDR missing error ).

i did a reinstallation on top of the new winxp copy on the new drive, and now there are double copies on my boot drive.
what i wish to ask is ,

1. which is the CURRENT windows folder? [WINDOWS] OR [WINDOWS.0]? is it recommended to just delete the old windows folder?

2. i previously installed msn messenger on the previous winxp copy. however, currently it doesn't allow me to reinstall the program, even though i've manually deleted it from the program files folder. how do i get xp to recognize that i need a new installation? ( i have the full standalone copy )

I've done that :thumbsup:.

Windows should be the original install, with Windows.0 being the second install. But...don't assume, check. If you have programs installed in one, but not the other...that's easy to check. Boot into each and find the programs you want to keep and remember which one that is.

As for which you are in...that depends on which you boot into. Both should show up initially when you boot. If you do not choose one or the other, it goes into whichever is set up as the default install.

You can boot into the one you want to keep and just delete the Windows folder of the other. Then follow the procedures outlined in Removing the invalid entries from Boot.ini - http://windowsxp.mvps.org/bootopt.htm and everything should be OK.

hi there,

it doesn't let me choose which to boot in @ startup. that's precisely the reason why initially i installed a 2nd copy of windows. The MAIN drive letter was changed from M: to C: after my SLAVE drive was fully formatted, resulting in NTLDR not found.

even after installing the 2nd copy, it boots straight into the new copy, and that's all.

hmm, if Windows.0 is the newer install, is there any way i can rename it back to Windows without any conflict? i'm sure there'd be a lot of problems by just renaming it right? my reason for renaming is because some patches will, by default, point to the Windows folder instead of Windows.0 . that's why.

Thanks for advice!

<<The MAIN drive letter was changed from M: to C: after my SLAVE drive was fully formatted, resulting in NTLDR not found.>>

Partitions/drives have letters assigned. How many drives are attached to this system and what partitions are on each drive? Which partition has the XP into which you boot?

If you want your current boot drive to be designated as the C: drive/partition and it currently is not...then the easiest way that I know to make that happen is to...temporarily disconnect everything (including flash drives) but the drive that XP install is on and your CD/DVD drive...then do a repair install.

As for what programs are installed in Windows.0 as opposed to Windows...I thought that I had explained that. One has nothing to do with the other. Programs installed while you are in Windows.0 will only be reflected in that install, while programs installed in Windows will only appear in that install.

You can see the folders for each from the other...but you cannot run programs on one from the other.

I would delete the Windows folder/install I did not want before I did the repair install.

After doing that, I would follow the procedures set forth in Removing the invalid entries from Boot.ini - http://windowsxp.mvps.org/bootopt.htm

I then would do the repair install of XP on whichever install I wanted to keep...in the manner that I described above.

Upon completion of the repair install and installation of necessary critical updates from WinUpdate, I would simply attach any other drives I wanted to use...and move forward.
