How to Install Grub2 on USB from Linux: In the following tutorial, I'll show you one way to easily install Grub2 to a USB Flash Drive from a running Live Ubuntu Operating Environment. I personally used an Ubuntu Live CD to perform all of the following steps.
For about a couple of years I've been using Supergrub from a USB to boot. After the first prompt, I select 'boot manually', then 'operating systems', then finally Windows or Linux - very cumbersome. I must have installed grub once before, but now its a problem:. Using grub4dos, I have just now created a USB under puppy linux live (version Fat Dog) which works OK. This shows me that my basic method is OK. I want to transfer what I did to the USB to the Master Boot Record (MBR) on the hard drive.
Currently, when I boot without any of the many boot aids I've created, it goes to grub-rescue with the message: 'Unable to find /boot/grub2/I386-pc/normal.mod', not a new thing according to the internet. Here is the nub of the problem: When I try to write the MBR using grub4dos under the live Fat Dog version, it tells me that the partition containing Windows is mounted read-only (ro). Persisting fails. I have tried 2 other puppy linuxes: Quirky and Lupu.528. All show the same behavior. With nothing previously mounted, I issue 'mount -o rw /dev/sda1 /mnt'. The resulting mount table shows sda1 mounted as ro.
Trying unmounting, then remounting does not change anything. In trying to install it using Windows, rather than Linux, the instruction is to use 'bootlace.exe'. But that program refuses to run on a 64-bit machine. But even a 32-bit compatibility fix won't work: its messages say 16-bit. Have not tried any compatibility solutions - hoping for an easier path. While there may be other strategies for getting a good grub boot onto my hard drive, I seem to understand this a bit. It seems like a catch-22, but I don't believe it.
Hundreds (or thousands) of folks have done this. There must be something I am missing or just do not know. Posting the question spurred me to search widely about running bootlace. Somehow, an answer came up regarding bootlace in the cloud. At first it looked cumbersome, like scratching your left ear with your right hand. Reading through all of it showed: 1. The solution offered worked by copying the first 63 bytes of the MBR or partition mbr to a file; 2.
Selecting the options wanted 3. The web page for bootlace in the cloud uploads the file, transforms it as bootlace would do, repackages it wuth the original 63 bytes (.backup), the new 63 bytes (.bin), and the log, all within a zip file which you get prompted to download. After unzipping the result, one must copy the resulting bytes back to the MBR. Note that, in filling out the bootlace details, if you want to do the MBR, you must leave the partition space blank.
All of this is aided by a new factor: grub4dosToolboxForWindows.exe, version 0.21 or later. Specifically, step 1 and step 4, last part, is accomplished by this software. Beyond that, the only things I needed to do was to ensure that some form of grldr, and menu.lst resided at C. To be safe, I copied both grldr and grldr.MBR to C: as well as the 2 submenus for menu.lst. I did not create these, they appeared after succeeding with the USB mentioned in the original post. A second issue which may have contributed to success: I had been using grub4dos 0.4.4, and was aware of no later version. The bootlace in the cloud page showed many more and later versions from 2009 - 12/2015.
So I upgraded to the latest version, 0.4.6. These were not found by general web searches as I would have expected. Happy grubbing!
