Re: Moving GRUB2 from one bootable HDD to another
There are lots of other ways you can install and use GRUB from various other kinds of media.
If you can spare the cash for a USB flash memory stick of 8GB or larger capacity, you can install Ubuntu or Lubuntu into the flash memory as an auxilliary Ubuntu or Lubuntu installation. It will have its own GRUB in it and if your computer's internal operating systems aren't already in its boot menu you can run 'sudo update-grub' in your USB installation to update its boot menu and boot operating systems in any computer. It's convenient at times to have an auxillary Ubuntu or Lubuntu installation rather than just use a Live CD for working on your regular hard-disk Ubuntu or Lubuntu installation.
If you want to save money and you have a spare USB lying around for file storage, you don't need to use an entire flash memory stick if you only want a GRUB boot disk. You can install GRUB in it and use it as a GRUB boot disk. You will need to install a GRUB folder in it for the boot loader files. They won't take up much room or harm your existing files in your USB. You'll need to run a special GRUB command to make the GRUB boot memu file for it.
You can make a GRUB Rescue CD or a floppy disk using the grub-mkrescue command.
You could use a partition editor and shrink Windows 98 a little and make a dedicated GRUB partition in the first hard disk.
You could lave the Windows 98 partition as it is and install GRUB inside Windows 98, but do not install it to the partition boot sector. By using the approriate commands it is possible to have a GRUB folder inside Windows 98 and boot both Windows 98 and Ubuntu from it.
