The HDD (hd0) contains several partitions including a Windows installation and several Debian installations. GRUB was installed by d-i in the usual way, which is in the MBR unless I'm mistaken.
I don't know what boot program is on the flash drive's partition. Could that be syslinux? The memory stick I used came with a FAT16 partition which I didn't touch. I created the stick following section 4.3.2.1. Partitioning the USB stick of lenny's installation guide. http://d-i.alioth.debian.org/manual/en.i386/ch04s03.html#usb-copy-flexible I did not use mkdosfs (though I could easily try recreating the partition with it if that's what determines what's in the FAT's MBR). > > Any other info you can give us? Anything you want. Something I omitted to mention initially is that the ECS K7S5A is a pre-2003 motherboard, which is in the beginning of "advanced" boot possibilities. I guess that once mbr has started, this is irrelevant, but I don't know. Setting the BIOS to boot from USB HDD won't work, I had to set it to boot from USB FDD. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
