Hi, I don't know how to fix this. I used an ISO image burned to one USB to install Debian to a second USB. I did this twice, with just one difference:
1) At the end of the install, both USB are connected to the computer. When the text installer prompts me, I remove the installation USB, then press Enter. The new Debian system boots. 2) At the end of the install, both USB are connected to the computer. When the text installer prompts me, I remove the installation USB, then press Enter. But this time while the BIOS is posting, I remove the second USB and let my computer boot into Windows. I then completely power off the machine. I then re-attach the second USB with the installation. Computer boots to Windows. The second USB doesn't boot. I should add I am blind and cannot see the messages that a potential bootloader might output. I ran this contrived test because the bootable USB drives I installed on only booted once. (While trying these scenarios, I'm getting quite familiar with all the numeric menu choices in the text installer.) When the installer boots, it is attached to /dev/sdc. (I have two built-in hard drives.) During the install, the target USB drive is at /dev/sdd. But when I'm booting the system with only the installation target USB attached, that probably is not /dev/sdd at that point. It would probably be /dev/sdc, if the kernel knows about such things at this point. I'm not sure if this is my problem. I have read about Grub refering to hard disks by number, like hd0. But I just don't know what to do. I don't want to modify my original Windows boot drive with a bootloader. All I want is to boot into Debian when I insert the USB. But I'm really stumped. Alan
