First of all, since it's my first post, Hi everyone Background: I have a 250 gb drive that once housed a cozy W2K SP4 installation and a lot of data in one partition. It suffered a fatal crash i was not able to recover, i have now to install on that same drive from scratch, without losing the data. I now have a XP SP2 integrated bootable CD, that's because i heard that SP2 will install no problems from scratch on Big LBA drives. Question I tried an install on a small drive (12 gb) and it is indeed installed as Windows XP SP2, but the EnableBigLba registry key is nowhere to be found. Is that normal? Can i go and try install on the large drive without risking data loss?
