Hi, I have a dual boot system with windows 2000 and XP. I have 2000 in partition C: and XP in partition D:. I have problems with 2000, sometimes not boot. I would like reinstall 2000, I will have any problems with that? Thanks for your help.

You shouldn't, just delete the current partition, create a new partition and install it on that

You can re-install W2K to current location, A few options/routes to consider first? 1) Try a Repair of current installation - it may resolve present problems. 2) If it doesn't fix it all then go the 'Upgrade of current installation route'. This too may resolve it all. If neither of the above succeed, you can either: 3) Install a second/parallel version in C: - (and also all the apps/utils for W2K afresh for this second version). Verify it boots OK, then delete the original version, also edit out references to it in the boot.ini. The second version will default to (go in as) windows; but you can change this whatever you wish - but not winnt (this is already in use by current W2K installation). Suggest you use win2000 - or something like? Then defrag C: once W2K in OK. or 4) Via XP... delete the current version (in C: ); then defrag the drive; then reboot and re-install W2K etc. to C: . Note: At present XP provides the mbr and the boot/files for both OS; i.e. XP is in charge... When you run W2K setup it will overwrite/replace the XP version of mbr/boot-files with W2K versions, and take charge... This will remove access to XP - temporarily; XP arrived after W2K in M$-land, so W2K etc. don't know about it... Once W2K is running OK, run XP setup and choose the repair routine to restore the mbr/boot-files to XP version. This will pick up W2K in the process and re-establish the dual-boot. Do all set-up routines via a CD boot (or appropriate floppies) - not from within an installed OS. *** 5) One other option - not one I'd go for unless really essential/really comfortable with it all ... It's too easy to screw up if not totally "au fait" with it all...? If C: = fat32 you can reformat the C: drive/partition - via a '98 boot-disk; reboot and then start a fresh install of W2K etc. (CD boot/4 floppies as above). Also since W2K set-up allows the (re)format of partitions you could reformat C: during set-up (fat32/ntfs) and re-install W2K afresh. As before, XP access will be lost until you have re-installed W2K, and then run XP repair routine. Either routes (3) or (4) should do all that's required if (1) or (2) fail to resolve it all. (5) is really a last resort option.
