You will probably be better off to just REFORMAT the whole disk and start over, after getting the files you need to save off if you haven't allready...
You can make some Boot floppys with Fdisk on them and use these to Clean the drive, then use Partition Magic to set up the new Partitions, It just works easier for me when I am doing formating and splitting up the drive...
If the errors remain even with Fdisk,(you can also, at a dos prompt, booted from a floppy, type "fdisk /mbr" and see if this reinstalls the Partition info on the drive, but I really don't think this will do it in this case)
You may have to use a utility from the maker of your hard drive to "fix" these errors.. You can go to most drive makers web sites and get these "repair" tools... They are Drive specific, so make sure and find out the exact name of the drive and the Model...
I personaly don't use those goofy Dell or Gateway Cds because they put a bunch of stuff on your computer that is un-nessasary, and for me, "gum up the works" and make the computer slugish and NOT optimized...
Just because it a Dell or Gateway, doesn't mean that you can't use it without all the added software that is UN-NEEDED.. These are made from Parts, just like the Home builts that I produce, and DO NOT need to use those "Advertisement Disks" to work properly...
BUT, unless you are very familier with Partition Magic, and how Partitions are set up and how hard drives are structured, you need to just "use the disk"...
If you DO know how to use Partition Magic, and know about the disk structure, etc., then you can set up a Primary Partition for a 9X system, and set up another Logical Partition for XP, (XP just needs to put the boot files on the root dir on the primary partition) and can be installed on a logical partition...
If you want to Run win 2000 and XP, that is easy to do with Logical Partitions also, but the boot files need to go on root directory in C drive (Primary)....
If you know how to use Partion Magic, you can make your Partitions any size you want, and any file system you need, and setup to install you Operating systems, in any order you want..( although you should Always install the Oldest First)...
You can use Other Boot managers, but the one with XP or 2000 works great for 2 or 3 operating systems to choose from on boot up, OR you can use something like System Commander, and boot up to like 100 systems if need be... but again, you need to know about, and have Experience with system boot managers to use this Correctly....
I have built, fixed,repaired and sold Computers for ten years now, and unless you know a little about Partitions and the drive structure, use the disk, but to really USE the Computer, throw the disk away and DO it Right
Working with Computers is like working on cars, some people "think" they can do it, and really mess things up, even though when you watch someone that "knows" how to work on one, they make it LOOK so EASY...
