Just a guess, but you may have 1024 Cylinder problem. 

Similarly, a number of BIOS's will only boot on partitions with the
first 2GB. For this reason, I usually setup 512MB Boot/Primary
partitions, then throw everything else after the Boot partitions. 

eg 

Disk /dev/hda: 255 heads, 63 sectors, 524 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot   Begin    Start    End   Blocks   Id  System
/dev/hda1            1        1     65   522081    6  DOS 16-bit >=32M
/dev/hda2   *       66       66    131   530145   83  Linux native
/dev/hda3          132      132    196   522112+   7  OS/2 HPFS
/dev/hda4          197      197    524  2634660    5  Extended
/dev/hda5          197      197    201    40131   82  Linux swap
/dev/hda6          202      202    331  1044193+   6  DOS 16-bit >=32M
/dev/hda7          332      332    524  1550241    6  DOS 16-bit >=32M


This is my Setup. Notice how I've got the Linux Swap in the extended
partition. For the interested the partitions are: DOS/WIN95(C:),
Linux, NT 4.0, FAT16(D:), FAT16(E:).
