Ok, I got it to install, everything is partitioned correctly. Great.
I booted it for the first time (expecting GRUB or Lilo) and got a "Could not detect operating system" message. I used my trusty boot floppy and set the Windows partition as active (that's what I'm going use most frequently). Then, I ran fdisk /mbr. I didn't know if the MBR was corrupt and wanted to be safe. Then, it booted right to Windows. No bootloader at all. But Windows worked. Which is good.
So then I followed these
instructions to dual-boot using the Windows bootloader. Everything went well with that, and I get the Windows bootloader menu. Windows boots fine, but when I go to boot Ubuntu, I get nothing but a black screen with a white blinking cursor in the upper left.
Anything I can do? Can I install GRUB or something? I'm using NTFS, though, for Windows, and I don't want to jack anything up. I also cannot format my Windows partition.
Thank you for your help this far!
