Thanks very much for that link and the info. The first partition on the slave (hdb) is a small primary partition intended for /boot (cyl 1 to 13), however I didn't specify that when installing Ubuntu, so it put /boot under its / partition, which is at a cylinder greater than 1023 (it's at 2820).

However, I don't think that's the problem because Ubuntu overwrote the MBR on the primary (Windows) drive (without asking me!) and it boots just fine from there. It seems like I should get the same error if it was a cylinder limit issue (this is a Pentium 4, so it should be new enough not to have that problem, I would think).

I was trying to implement the article's technique so that I would be able to restore the MBR to Windows, so that the Windows drive would be independent of the Linux drive. I tested it by by choosing Windows from the Ubuntu menu, then choosing Ubuntu from the Windows menu, which I had set up according to the article.

Since I have the partition available, I could test by installing the Ubuntu bootloader stuff to it, but I'm not sure how to do that (grub-install and copy all /boot files, I guess). I'll have to read more about GRUB before I try anything else.

    So, GRUB is installed in your system's primary drive (which is where it "wants" to install itself by default).

    At start-up time, does GRUB provide you with an option to book Windows or Ubuntu?

    If you select Windows, does the system correctly boot into Windows? And does your Windows system still work, letting you run Windows programs, seeing the correct drives and disk space, etc.?

    Finally, if you select Ubuntu at start-up time, what happens?

    It's not a disaster that GRUB installed itself on your MBR, as long as it correctly identified your Windows operating system and lets you boot into Windows properly.
