OK, the first thing you will need to do isa recombine the partitions. I would use a program such as "Partition Magic" but if you dont have it, or used a program such as FIPS, use its recovery methods. Then, make a Win98 boot disk. Boot from it. Type in sys c: . That will replace the NTDLR, BOOT.INI etc, back to the good old IO.SYS, MSDOS.SYS and COMMAND.COM. This gets rid of the dual boot screen.
If you dont have the partitioning utilities above, you will probably need to have a seperate partition. To get this (from a NTFS partition), you will need to re run the setup program from DOS and fromat the old NTFS partition to FAT32, then restart. EASY.
Another way of combining it would be to get another hard disk - exactly the same. Make 1 BIG FAT32 partition and use a utility (FIPS - get a RedHat CD and copy it & RESTORERB.EXE) and fips the partition to similar sizes. Then use Restorrb to make it one disk again. THEN, use that same technique on the other hard disk to make 1 partition. EASY
Hope that answers your question
