I need some step by step advice to get grub set up the correct way.
1) I need to install grub on /dev/sda so it only boots Windows, /dev/sda2, regardless of whatever other devices may or may not be connected. I cannot use fdisk.exe /mbr because I don't have it and can't get it. Windows is currently my only way to write a cd or dvd. wodim isn't working. /dev/sda is an internal hard drive.
2) I need to install grub on a secondary USB flash drive so I have a backup stick from which to boot without having to boot from the installation cd again.
3) I need to set up a simple USB flash drive as a boot device that will automatically boot /dev/sdb1 regardless of whatever else may or may not be connected, and then make a second copy of that. /dev/sdb is an external USB hard drive. It is always registering as /dev/sdb without fail.
4) I need to create a cd iso image and write it to a blank cd, and then make a second copy of that. I need either cd to boot /dev/sdb1 regardless of whatever other devices may or may not be connected. /dev/sdb1 is the root Linux file system.
5) I need help getting wodim to work. It writes the disc, and says it didn't have any problems, but I can't mount or access the disk. I used geniosimage to make the iso image from files in a directory. I tried to create a simple non-bootable data disc using iso9660. The image file was approximately 1.6 GB.
I am currently booting from a USB flash drive by catching grub during the boot process when the menu appears and asking for a command prompt. I then use the following commands:
grub> linux (hd0,msdos1)/vmlinuz root=/dev/sdb1 ro
grub > initrd (hd0,msdos1)/initrd.img
grub> boot
(hd0) is a 32G USB flash drive with a single dos mbr partition on it. It uses an ext4 file system.
