This depends on what exactly you did when you installed Dreamlinux on your system. How did you deal with the partitions? DL should have noticed that there was a windows system already on the HD and given you some options for how to deal with it and how to partition your HD. Can you describe what you did?
cheers,
jdk

Go get the bootinfo script from sf.net - run it from the liveCD and post the RESULTS.txt so we can see what's what.

post us your config file from your grub (dreamlinux on hdd). -> /boot/grub/menu.lst

and the result of below command (as a root):
Code:
fdisk -l

All that and plenty more is produced by the script.

I think the error message is from the BIOS and just means it can't find boot code in the mbr (of the device from which it is set to boot). The BIOS thinks that if it finds boot code, everything is fine----it knows nothing of operating systems.

You can install GRUB from any Linux Live CD.

I seem to recall that grub doesn't support ext4 yet. Am I mistaken and, if not, could that be (part of) the problem?

that could be it.
http://ext4.wiki.kernel.org/index.ph...xt4_filesystem

anyway try to install most recent grub and reinstall it in mbr

for example:
Code:
root (hd0,1)
setup (hd0)

No operating system found
Is a message from the BIOS. It has not even tried to read the boot drive. Your BIOS is probably checking the bootable flags on the partitions on the drive.
Many BIOSes don't bother, others need exactly one partition to be flagged bootable.

Look with fdisk -l
Code:
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1           5       40131   fd  Linux raid autodetect
/dev/sda2               6          70      522112+  82  Linux swap / Solaris
/dev/sda4              71      121601   976197757+   5  Extended
/dev/sda5              71         724     5253223+  fd  Linux raid autodetect
/dev/sda6             725      121601   970944471   fd  Linux raid autodetect
If you don't have it set (or have too many set), use fdisk to fix it. Its harmless to your data
