Unerase tool that marks deleted file as present

First thing that comes to mind is Linux ntfsundelete:
When files are deleted a flag in the MFT is merely changed. I'm trying to find an unerase tool that is capable of changing that flag back without actually copying the file to a different location. I have been testing like a dozen tools and not a single one supports this way of data recovery. If I was still running on FAT, I'd use DOS 6.22's "undelete.exe" since that one actually did it that way, but I'll be damned if there isn't a modern equivalent. Does someone happen to know a tool that supports recovering a file without actually copying its content to a new location?
Running an undelete software in a running NT based systems is risky, that's why most programs, like Testdisk:
won't t let you simply UNflag the $MFT entry.
And same goes for most tools, another example:
A port of the Linux tool may work for you:

ntfsundelete looks like it does the trick. The windows port doesn't seem to support SATA-discs, so I'll have to dig out a Linux live CD first, but it's finally a solution I almost thought wouldn't exist.

Are you sure?
The windows port doesn't seem to support SATA-discs, so I'll have to ....
Device support should be unrelated to actual program.
Or maybe that port is very old?
But still, if a device is supported, a filesystem driver or tool should work independently, SATA is a form of ATA, it's not like it was a SCSI device.
But anyway - as said - it is much better to NOT run something like that on a "live" NT system.

Before going through the hassle of recompiling the toolset myself I'd rather try to find another (preferably cygwin based) windows version (there must be several according to wikipedia) or - as a last resort - use a live CD. I'm not too Linux savvy, so this is my least favorite choice, plus the live CD allen2 suggested doesn't seem to like EasyBCD's ISO boot and doesn't boot successfully. However, I heard every Ubuntu live CD has ntfsprogs pre-installed, so I'll give those a shot before I give up on finding a working windows version.
Update: I got around trying ntfsundelete. Excellent tool, however, it does not support restoring files without copying them. The "undelete inode" option is a bit misleading here. In fact, you have to specify a destination directory or else ntfsundelete will copy the file to the current user directory by default. Still, great tool that I'll certainly use in the future. At least I was able to find out quickly that the file I was trying to restore already had its MFT entry overwritten.
